Tatuajes de convictos, heterotopías del infortunio
Authors: Rodríguez-Luévano Álvaro
Published: July 2017

Este trabajo propone una reflexión sobre los lugares físicos y heterotópicos que ocupan los tatuajes de los convictos en una dimensión emocional de la marca corporal. También atiende los deslizamientos simbólicos y formales de los dibujos y el examen de los modelos que conforman una cartografía epidérmica de los convictos y delincuentes. Los estudios del tatuaje en años recientes producen una amplia literatura que vincula la mirada médica, criminológica, artística y cultural. El fenómeno de las marcas corporales tiene consecuencias en ámbitos muy diversos de la imagen, pero también muy significativos en la esfera de lo sensible y de la memoria del cuerpo.
Notas al pie de Gaza, de Joe Sacco: el anacronismo como posibilidad de acceso a la experiencia límite

Published: July 2017

Nos adentramos en las posibilidades de la novela gráfica como una plataforma discursiva de crítica social que reactualiza y tensa el otrora paradigma del arte comprometido. A partir de las ideas de Georges Didi-Huberman en Ante el tiempo, iremos desarrollando el análisis sobre la “modernidad del anacronismo”, la funcionalidad de la “imagen-combate” y la efectividad de la “imagen-aura” en la propuesta de Joe Sacco. La problemática central del estudio se debate en la "lucha" entre palabra e imagen; esta última, en tanto dispositivo de acceso a la experiencia límite para reconstruir la memoria histórica del acontecimiento.
Revisión sistemática de literatura sobre comportamiento político y juventud en Latinoamérica y Costa Rica desde 1990 hasta 2016
Authors: González Sancho Roy
Published: July 2017

Este artículo presenta la sistematización de las investigaciones relacionadas con el comportamiento político-electoral en Costa Rica y Latinoamérica (inclusive algunos casos de España). Se enfatiza en el tratamiento y las ausencias del tema de juventud en este ámbito. Con un enfoque cualitativo y mediante la metodología conocida como revisión sistemática de literatura, se seleccionaron 124 artículos científicos de revistas indexadas en Redalyc.org y Kimuk.conare.ac.cr principalmente, estos fueron analizados con el programa informático AtlasTi7. Se encontró que el interés académico se enfoca en la participación política al margen de los demás temas. Se concluye que la credibilidad y la confianza políticas tienden a confundirse en su tratamiento, mientras que los abordajes de juventud tienden a ser menos en relación con el grueso de la investigación sobre el comportamiento político.
Photovoltaic Power Conversion System Based on Cascaded Inverters with Synchronized Space-Vector Modulation
Authors: V. Oleschuk  , J. Tlustý  , V. Valouch
Published: July 2017

The paper presents results of investigation of dual-inverter-bases power conversion system with synchronized pulsewidth modulation (PWM) for photovoltaic application. This system topology includes two insulated strings of photovoltaic panels, feeding two standard three-phase inverters, connected to grid by a three-phase transformer with the open winding configuration on primary side. Algorithms of synchronized PWM provide in this case continuous voltage synchronization both in each inverter and in the load. Simulations show a behavior of the systems with low switching frequency, with both continuous and discontinuous versions of synchronized PWM.
Performance and measurement of power quality due to harmonics from street lighting networks

Published: July 2017

The municipality government of San Miguel de Tucumán city in Argentina is interested in applying energy saving policies to street lighting facilities. In this frame, devices like astronomical programmable clocks and electronic control gear (ballast) will be used to replace photocells and inductive control gear. Also luminaries in use could be replaced by more efficient ones. A technical-economical evaluation was necessary and the technical aspect was request to the Lighting Department of Tucumán University. The performance of the devices and the power quality impact in the lighting networks evaluation was also necessary to evaluate. The study carried out involved outdoor and laboratory test. During 1,5 month six lighting networks with 273 semi-cutoff luminaires were tested. Network selected belong to residential areas which represent more than 60% of total city lighting facilities (26.000 luminaires). In addition laboratory test were conducted with a sample of inductive (in use) and electronic control gear, for high pressure sodium discharge lamps (HPS) 150W. Performance varying voltage input for aged was analyze. Some results from tests points out that: • The use of programmable astronomical clocks instead of photocell produces 11% of energy saving because of actual time on and off schedule set. • Electronic control gear instead of inductive control gear produces 28% energy saving. • Luminaire replacement of current HPS 150W by HPS 100W with Electronic control gear and photocell control produces 43% in energy saving. Outdoor test results from measurement of electrical input parameters and harmonics of existing inductive control gear in street lighting, indicate that: while THD V voltage is about 2,8%, THD A current can be reduced from 38% to 6,5% even when electronic control gear is set to the lower output power step (70% of power output and 60% of initial average illuminance value). The results obtained will be used as arguments for the widespread replacement in the city which would involve considerable investment and a new experience in the region.
Supply security and the reliability of the Spanish generator system in the next two decades based on the costs of fossil fuels and nuclear option.
Authors: F. Delgado  , A. Ortiz  , C. J. Renedo  , S. Pérez  , M. Mañana
Published: July 2017

The supply security of the primary energy sources (coal, natural gas, enriched uranium…) and the reliability of the system in terms of the oscillations of the frequency and voltage are two aspects to assess in the Generation Expansion Planning. In this article, for the first criterion, the evolution of vulnerability and degree of independence of the generator system with respect to primary energy sources has been assessed by the indexes of Shannon-Weiner and energy independence, respectively. For the second approach, the evolution of the reserve margin by means the coverage index and the progression of the inertia and regulation capacity by means of its percentage regarding the total installed capacity. These four indexes have been applied on the obtained results of a stochastic lineal model developed with the software GAMS. In this model the nuclear technology has been considered as generation option in several scenarios of costs of the fossil fuels, coal and natural gas. Also, two of clean coal technologies with greater possibility of putting into service have been taken into account. The final conclusion would be that each technology carries out several functions in the generator system but not all them. That is, a generator system should have the greatest possible number of types of generation to be reliable and have supply security.
Micro grid stabilization using the Virtual Synchronous Machine (VISMA)
Authors: Ralf Hesse  , Dirk Turschner  , Hans-Peter Beck
Published: July 2017

Up to now, the electromechanical synchronous machine rules the domain of electrical power generation devices and that way the public power grids. Its specific characteristics guarantee the stable highly parallel grid operation, automatic power balancing and damping. Not least the rotating mass is related to some dynamic properties and the condition for the grid short time frequency stability. The progressive integration of renewable sources is accompanied by questions concerning the loss of these features using inverters for grid feeding. The paper shows an approved concept that combines inverter technology and synchronous machine properties.

A Kriging-Based Partial Shading Analysis in a Large Photovoltaic Field for Energy Forecast
Authors: Annalisa Di Piazza  , Maria Carmela Di Piazza  , Gianpaolo Vitale
Published: July 2017

In this paper the use of the kriging estimation method for the study of partial shading in photovoltaic fields is investigated. Different cases of shadowing spatial distribution on the PV field surface, due to different relative positions between the plant and some clouds, are studied. The adopted method gives a spatial interpolation of the shadowing so that its distribution over all the surface can be obtained on the basis of a limited number of experimental data. In all cases the kriging estimates are nearly the same as the observed data, also when a strongly reduced experimental observations are available. The accuracy of the estimates is also confirmed by Q-1 and double kriging cross validation schemes. The followed approach allows a cheaper and simpler characterization of the PV plant output power allowing energy forecast.
Velocity-Controlled Piezoelectric Switching Energy Harvesting Device
Authors: Yuan-Ping Liu  , Dejan Vasic  , François Costa  , Wen-Jong Wu  , C. K. Lee
Published: July 2017

The main purpose of this paper is to design the interface circuit of the piezoelectric energy harvesting device which can be suitable for a resistive load o a capacitive load. The vibrating velocity is detected to control the active rectifier to make the power factor correction of the piezoelectric layers. However, there are switching losses in the active rectifier in practice. The dead time and an inductor are thus taken into consideration to minimum the switching loss. The proposed circuit can increase 4 times than typical interface circuit of the piezoelectric layer, and can increase the charging speed of the capacitive storage buffer as well.

Authors: H. A. Dharmawan  , S. A. M. Ali
Published: July 2017

This paper describes research development focusing on the designs of switchable transformers and their control system at University of South Australia. Research development of switchable transformer has become one of the major research interests in school of Electrical and Information Engineering, University of South Australia since year 2000. Research in this area has been carried out through undergraduate to post graduate studies. Several transformer designs, starting from the rating of 1kVA to 10kVA, have been introduced. Testing results from the designs have shown the improvement of the transformer efficiency during low or high loads. As the switchable transformers utilize several switching devices that need to be synchronously controlled, research on the development of the switchable transformer control systems has also been carried out. Now, in this school, a study of utilizing controller area network (CAN) as media to integrate modules in the control system is done. The study also focused on the remote monitoring and control system of the switchable transformer through a local area network (LAN).

The rules of Hungarian Criminal Procedure Code related to summary proceedings aren’t newfangled. Probably, due to the criminal policy needs, arise from that, recent years these changed considerably and in a sense went through “volte-face”. To emphasise the strong connection between this special process and the investigation, I review the rules of some surrounding states that apply to this, in order to point out in a constructive way the problems of the operative Hungarian regulations. I’d like not only to line up these for the Reader but – in search of optimal key – also make de lege feranda proposals.

KEDUDUKAN PERATURAN KEBIJAKAN DALAM UNDANG-UNDANG ADMINISTRASI PEMERINTAHAN
Authors: Nalle Victor Imanuel
Published: July 2017

Abstrak
Prinsip diskresi adalah prinsip yang penting sebagai panduan bagi pemerintah untuk mengambil tindakan. Sebagaimana halnya hakim yang tidak boleh menolak perkara dengan alasan tidak ada hukumnya, maka pemerintah pun tidak dapat menolak mengambil tindakan dalam keadaan genting dengan alasan tidak ada dasar hukumnya. Produk hukum yang merupakan keluaran dari diskresi tersebut berupa peraturan kebijakan (beleidsregels atau policy rules). Walaupun dalam praktik penyelenggaraan pemerintahan seringkali menggunakan peraturan kebijakan tetapi belum ada peraturan perundang-undangan yang mengatur penggunaan peraturan kebijakan sebagai bentuk diskresi. Undang-Undang Nomor 30 Tahun 2014 tentang Administrasi Pemerintahan sebagai payung bagi hukum administrasi negara di Indonesia juga tidak mengatur peraturan kebijakan. Tulisan ini akan mengkaji konsep peraturan kebijakan untuk diintrodusir ke dalam UU Administrasi Pemerintahan agar terdapat pengaturan yang utuh dari diskresi hingga bentuk-bentuk dari diskresi, salah satunya peraturan kebijakan.

 

Abstract
The principle of discretion is an important principle as a guide for the government to take action. As in the case of judges who may not refuse a case with no legal reason, then the government can't refuse to take action in conjuncture with the reason no legal basis. Although in practice governance policies often use policy rules, but there is no legislation governing the use of policy rules as a form of discretion. Act No. 30 of 2014 on Public Administration as an umbrella for administrative law in Indonesia is not set policy rules. This paper will review the policy rules concept to be introduced into the reform of Public Administration Act. The reform of Public Administration Act will make the Act have the whole concept of discretion.

Study on the frequency of heavy rainfall in Huong Khe district, Ha Tinh province
Authors: Le Quang Dao
Published: July 2017

Rainfall intensity, duration and frequency of 24 consecutive hours or longer (48h, 72h, 96h) are very essential for the assessment of flood risk and the design of the reservoirs and dams in Huong Khe district, Ha Tinh province. The analysis of flood-causing rainfall and the actual floods from 1990 to 2012 has shown that floods usually occur when: a) 24-hour continuous rainfall reacheds 710.6mm or more; b) Heavy rains which lasted longer than 24 hours and reached 548.9mm/24h to 630.2mm/48h or more; c) Heavy rains lasted from 72 hours to 96 hours and reached from 534.5mm/72h to 575.6mm/96h. The following conclusions have been drawn from analysis results of development of the empirical and theoretical exceedance frequencies of Pearson III distribution of 24h-96h heavy rainfall: a) All the theoretical and empirical frequency data have very high correlation coefficient from 0.891 (24h rainfall) to about 0.948 (72h-96h rainfall); b) For 24h rainfall, the actual rainfall of the empirical P of 13% to 26% is about 40mm lower than the theoretical rainfall, while the actual rainfall of the empirical P of 8.7% is about 80mm higher than the theoretical value, and that of the empirical P of 4.35% is about 175mm higher than the theoretical value; the actual rainfall at empirical P of 8.7% is corresponding to theoretical P of 4.5%, and actual rainfall at empirical P of 4.35% is corresponding to theoretical P of ~1%; c) For 48h and 72h rainfall, the empirical and theoretical frequency data are very close to each other for the P in the range of 8.7% to 30%, only empirical P of 4.35% is much far from theoretical one and corresponding to rainfall frequency of ~1%; d) For 96h rainfall, the empirical and theoretical frequency data are very close to each other for most P range, only empirical P of 8.7% and 4.35% are somehow far from theoretical ones and corresponding to rainfall of theoretical frequencies of ~4.5% and ~1%, respectively.

VULNERABILITY TO FLOODING AND COPING BEHAVIOR FOUND IN HOUSING CONDITION: A CASE STUDY IN VAN QUAT DONG VILLAGE, TAM GIANG LAGOON AREA, CENTRAL VIETNAM
Authors: Đức Trần Thanh
Published: July 2017

Vietnam is a country that is suffered from frequent natural disasters. The most common types of natural disasters experienced are typhoon and flood. From 1951 to 2010, there were 166 typhoons come to Vietnam, of which 67 % hit the central region, 25 % to the north and 8 % to the south of the country. Typhoons bring heavy rains and high tides which accelerate floods, particularly in the coastal and lagoon areas of Central Vietnam. Identification of vulnerability to flooding and coping behavior of local people is required in the efforts to strengthen local capacity related to livelihood security in the study area. This study aims at characterizing the vulnerability of housing condition to flooding and the coping behaviors of local people after experienced big floods in Tam Giang lagoon area, Central Vietnam. Measurement of house’s foundation, observation of types of housing, interview to collect information about the water level during the events of big floods, year of construction and change of people’s behavior after the 1999’s flood were conducted with 427 households in Van Quat Dong village where four big flooding occurred in 1983, 1999, 2007 and 2009 during the last 30 years. The study shows that the 1999’s flood was the biggest flood with water height reached to 148.7 ± 23.9 cmfrom house floor and 222.6 ± 15.4 cmfrom ground level. The households located in the eastern part of the village are recognized more vulnerable to flood due to the lower altitude. The temporary and semi-permanent houses, which share 77.0 % to the entire houses, are considered to be relatively vulnerable to flooding due to weak housing materials and low height of foundation. The houses which categorized to permanent and semi-permanent types constructed after the 1999’s flood have higher foundation than the other houses constructed before the 1999’s flood. The raising of foundation height of permanent and semi-permanent houses, as well as an increase in numbers of two-storey houses, are recognized to be a behavior of local people to cope with flooding. The study also shows the relationship between the poverty level and the coping behaviors of households. Some of poor households in the village are still not in good preparedness to flooding. It suggests that poverty level of household concerns to the vulnerability to flooding and, therefore, rural development assistance to improve household economy for poverty alleviation is required in the efforts to strengthen local capacity related to livelihood security.
Juvenal’s Appia de numero Lamiarum (6.385–397)
Authors: Kavanagh Bernard
Published: July 2017

Among the many women discussed in Juvenal’s Satire 6, the satirist’s tirade against the institution of marriage, one is a wife named Appia (6. 385–397), who is said to belong to the family of the (Aelii) Lamiae. Scholars have been divided as to who specifically the woman was, some believing that she was a member of the patrician Claudii of old, others that the reading Appia is corrupt. This article, while accepting the reading in the text as Appia, but not that she is not related to the ancient gens Claudia, argues instead that Juvenal’s Appia de numero Lamiarum was the daughter of L. Ceionius Commodus II, whose mother’s name was Appia Severa, and his wife *Plautia, who was the daughter of L. Aelius Lamia. Since Hadrian’s heir apparent, L. Aelius Caesar, was the son of that same couple, Appia must have been his sister, a fact not previously known.

The North Field Excavations at Vindolanda: Preliminary Report on the 2009–14 Exploratory Field Seasons
Authors: Greene Elizabeth M. , Meyer Alexander
Published: July 2017

Since 2009, work has been carried out in the North Field at Vindolanda, a Roman military fort in the frontier zone of Roman Britain. The excavations have been directed by the Vindolanda Trust, in conjunction with a team from the University of Western Ontario. Based on these first seasons, some significant preliminary conclusions about this area of the site can be made, which will be important in moving forward with further excavations and for future interpretations of the early occupation of this region by the Roman army. The North Field appears to have been occupied already in the last quarter of the first century and may prove with further excavation to contain a fort that pre-dates “Period I” at Vindolanda, settled in ad 85. The field also appears to have been an area of significant activity in the second and third centuries. Large stone structures and a fortified ditch enclosed at least part of the space in this period. These buildings were part of the thriving third-century extramural settlement explored extensively elsewhere at Vindolanda over the past decades. The findings from these five seasons (2009–2010 and 2012–2014) have led to further excavation campaigns in the North Field, which will continue for several more field seasons. This article disseminates the results of the exploratory trenches as the research moves forward with further excavation.
Patients' Perspectives on and Experiences of Home Exercise Programmes Delivered with a Mobile Application
Authors: Abramsky Hillary , Kaur Puneet , Robitaille Mikale , Taggio Leanna , Kosemetzky Paul K. , Foster Hillary , Gibson Barbara E. , Bergeron Maggie , Jachyra Patrick
Published: July 2017

Purpose: We explored patients' perspectives on home exercise programmes (HEPs) and their experiences using a mobile application designed to facilitate home exercise. Method: Data were generated using qualitative, semi-structured, face-to-face interviews with 10 participants who were receiving outpatient physiotherapy. Results: Establishing a therapeutic partnership between physiotherapists and patients enabled therapists to customize the HEPs to the patients' lifestyles and preferences. Analysis suggests that using the mobile application improved participants' ability to integrate the HEP into their daily life and was overwhelmingly preferred to traditional paper handouts. Conclusions: The results suggest that efforts to engage patients in HEPs need to take their daily lives into account. To move in this direction, sample exercise prescription questions are offered. Mobile applications do not replace the clinical encounter, but they can be an effective tool and an extension of delivering personalized HEPs in an existing therapeutic partnership.

We herein hypothesize that bioceramics with an appropriate architecture made of Si-αtricalcium phosphate (Si-αTCP) meet the biocompatibility and biological safety requirements for bone grafting applications. Polyurethane sponges were used as templates, soaked with ceramic slurry at different ratios and sintered at 1400 °C for 3 h at heating and cooling rates of 5 °C/min. Four critical size defects of 6 mm Ø were created in 15 NZ tibias. Three working times were established as 15, 30 and 60 days. A highly porous Si-αTCP scaffold with micro and macropores and pore interconnectivity was produced by the polymer replication method. Considerably more bone formation took place in the pores and the periphery of the implant for the Si-αTCP scaffolds than for the control group. The ceramic scaffold (68.32% ± 1.21) generated higher bone-to-implant contact (BIC) percentage values (higher quality, closer contact) than the control group, according to the histomorphometric analysis, and defect closure was significant compared with the control group. The highest percentages of BIC and bone formation were found after 60 days of implantation. These results suggest that the Si-αTCP scaffold is advantageous for initial bone regeneration.
Globalization, Inequality, Say’s Law, and Fiscal Globalism
Authors: Soldatos Gerasimos T.
Published: July 2017

This is a brief note maintaining that financial globalization has been faster than the integration of the remaining sectors of the world economy, thus encouraging wealth inequality, under-production, and under-consumption in line with Say’s Law. Financial investment has become more profitable than real investment, discouraging production ventures, and weakening labor’s relative income position and purchasing power. Moreover, this article works out a model of international government indirect tax competition as a policy means against increasing inequality. The mentality under which this tax policy paradigm is put forward is that the competition of nation states in a fiscal globalism fashion crystallizes the optimal level of centralization under globalism; optimal, that is, from the viewpoint of safeguarding against the manipulation of world markets by financiers.
A Novel Feature Extraction Method for Ship-Radiated Noise Based on Variational Mode Decomposition and Multi-Scale Permutation Entropy

Published: July 2017

In view of the problem that the features of ship-radiated noise are difficult to extract and inaccurate, a novel method based on variational mode decomposition (VMD), multi-scale permutation entropy (MPE) and a support vector machine (SVM) is proposed to extract the features of ship-radiated noise. In order to eliminate mode mixing and extract the complexity of the intrinsic mode function (IMF) accurately, VMD is employed to decompose the three types of ship-radiated noise instead of Empirical Mode Decomposition (EMD) and its extended methods. Considering the reason that the permutation entropy (PE) can quantify the complexity only in one scale, the MPE is used to extract features in different scales. In this study, three types of ship-radiated noise signals are decomposed into a set of band-limited IMFs by the VMD method, and the intensity of each IMF is calculated. Then, the IMFs with the highest energy are selected for the extraction of their MPE. By analyzing the separability of MPE at different scales, the optimal MPE of the IMF with the highest energy is regarded as the characteristic vector. Finally, the feature vectors are sent into the SVM classifier to classify and recognize different types of ships. The proposed method was applied in simulated signals and actual signals of ship-radiated noise. By comparing with the PE of the IMF with the highest energy by EMD, ensemble EMD (EEMD) and VMD, the results show that the proposed method can effectively extract the features of MPE and realize the classification and recognition for ships.
On Interrelation of Time and Entropy
Authors: Martyushev Leonid
Published: July 2017

A measure of time is related to the number of ways by which the human correlates the past and the future for some process. On this basis, a connection between time and entropy (information, Boltzmann–Gibbs, and thermodynamic one) is established. This measure gives time such properties as universality, relativity, directionality, and non-uniformity. A number of issues of the modern science related to the finding of laws describing changes in nature are discussed. A special emphasis is made on the role of evolutionary adaptation of an observer to the surrounding world.
Artificial Noise-Aided Physical Layer Security in Underlay Cognitive Massive MIMO Systems with Pilot Contamination
Authors: Al-Hraishawi Hayder , Baduge Gayan , Schaefer Rafael
Published: July 2017

In this paper, a secure communication model for cognitive multi-user massive multiple-input multiple-output (MIMO) systems with underlay spectrum sharing is investigated. A secondary (cognitive) multi-user massive MIMO system is operated by using underlay spectrum sharing within a primary (licensed) multi-user massive MIMO system. A passive multi-antenna eavesdropper is assumed to be eavesdropping upon either the primary or secondary confidential transmissions. To this end, a physical layer security strategy is provisioned for the primary and secondary transmissions via artificial noise (AN) generation at the primary base-station (PBS) and zero-forcing precoders. Specifically, the precoders are constructed by using the channel estimates with pilot contamination. In order to degrade the interception of confidential transmissions at the eavesdropper, the AN sequences are transmitted at the PBS by exploiting the excess degrees-of-freedom offered by its massive antenna array and by using random AN shaping matrices. The channel estimates at the PBS and secondary base-station (SBS) are obtained by using non-orthogonal pilot sequences transmitted by the primary user nodes (PUs) and secondary user nodes (SUs), respectively. Hence, these channel estimates are affected by intra-cell pilot contamination. In this context, the detrimental effects of intra-cell pilot contamination and channel estimation errors for physical layer secure communication are investigated. For this system set-up, the average and asymptotic achievable secrecy rate expressions are derived in closed-form. Specifically, these performance metrics are studied for imperfect channel state information (CSI) and for perfect CSI, and thereby, the secrecy rate degradation due to inaccurate channel knowledge and intra-cell pilot contamination is quantified. Our analysis reveals that a physical layer secure communication can be provisioned for both primary and secondary massive MIMO systems even with the channel estimation errors and pilot contamination.

Published: July 2017

This paper discusses the control of the linear switched reluctance machines (LSRMs) network for the zero phase-difference tracking to a sinusoidal reference. The dynamics of each LSRM is derived by online system identification and modeled as a second-order linear system. Accordingly, based on the coupled harmonic oscillators synchronization manner, a distributed control strategy is proposed to synchronize each LSRM state to a virtual LSRM node representing the external sinusoidal reference for tracking it with zero phase-difference. Subsequently, a simulation scenario and an experimental platform with the identical parameter setup are designed to investigate the tracking performance of the LSRMs network constructed by the proposed distributed control strategy. Finally, the simulation and experimental results verify the effectiveness of the proposed LSRMs network controller, and also prove that the coupled harmonic oscillators synchronization method can improve the synchronization tracking performance and precision.

Published: July 2017

Control of grid-connected power converters is continuously developing to meet the grid codes, according to which the generation units should keep connected to the grid and further provide ancillary services, such as voltage and frequency support, negative sequence current injection, inertia emulation, etc. A virtual admittance controller is proposed in this paper for the objective of voltage support under asymmetrical grid faults. By using independent and selective admittances for positive and negative sequence current injection, the unbalanced voltage can be significantly compensated during asymmetrical faults. The controller is based on the generic control framework of the synchronous power controller (SPC), which is able to control a power converter with emulated and improved synchronous generator characteristics. Simulation and experimental results based on two paralleled 100 kW grid-connected power converters demonstrate the controller to be effective in supporting unbalanced voltage sags.

Published: July 2017

In order to determine the matching relationship of polymer molecular weight and reservoir permeability in ASP (alkaline/surfactant/polymer) flooding, a number of core flooding experiments with different polymer molecular weights are performed. Two types of curves for the relationship between the pressure difference and the injection pore volume multiples are obtained. One describes the characteristics of the core plugging; the other describes the characteristics of the injection well. The relationship between the polymer molecular cyclotron radius and the pore throat radius used to describe the relationship between the polymer molecular weight and the core permeability. The results indicate that when the ratio of the pore throat radius (rh) to the polymer molecular cyclotron radius (rp) is greater than 7, the injection of ASP system with a variety of molecular weights will not be blocked; on contrary, when the ratio is less than 7, the core will be blocked. The range of water permeability of the core is determined by the value of the polymer molecular weight. The ratio between the pore throat radius (rh) to the polymer molecular cyclotron radius (rp) for the ASP system is greater than that of polymer system (rh/rp = 5). A scanning electron microscope (SEM) is used to compare the morphology of polymer molecules in polymer solution and ASP solution, and shows that the dimension of polymer molecular coils in ASP solution is smaller than that in polymer solution, which is caused by the double effect of alkali and surfactant.

Published: July 2017

Wind speed forecasting has an unsuperseded function in the high-efficiency operation of wind farms, and is significant in wind-related engineering studies. Back-propagation (BP) algorithms have been comprehensively employed to forecast time series that are nonlinear, irregular, and unstable. However, the single model usually overlooks the importance of data pre-processing and parameter optimization of the model, which results in weak forecasting performance. In this paper, a more precise and robust model that combines data pre-processing, BP neural network, and a modified artificial intelligence optimization algorithm was proposed, which succeeded in avoiding the limitations of the individual algorithm. The novel model not only improves the forecasting accuracy but also retains the advantages of the firefly algorithm (FA) and overcomes the disadvantage of the FA while optimizing in the later stage. To verify the forecasting performance of the presented hybrid model, 10-min wind speed data from Penglai city, Shandong province, China, were analyzed in this study. The simulations revealed that the proposed hybrid model significantly outperforms other single metaheuristics.

Published: July 2017

With the significant decrease in natural gas prices in many parts of the world, the employment of gas turbine (GT) units has increased steadily in recent years. The ever-increasing deployment of GT units is strengthening the interconnections between electric power and natural gas systems, which could provide a higher level of operational flexibility and reliability. As a result, the planning and operation issues in the interconnected electric power and natural gas systems have aroused concern. In these circumstances, the impacts of increasing deployment of GT units in power system operation are studied and evaluated through well-being analysis (WBA). The fast responsive characteristics of GT units are analyzed first, and the definition and adaption of WBA in a power system with increasing deployment of GT units are addressed. Then the equivalent reserve capacity of GT units is estimated, taking demand fluctuations, commitment plans, and operational risks of GT units into account. The WBA of a power system with increasing deployment of GT units is conducted considering the uncertainties of system operation states and renewable energy sources. Finally, the proposed methods are validated through an integrated version of the IEEE 118-bus power system and a 10-bus natural gas system, and the impacts of GT units on power system security under various penetration levels are examined. Simulation results demonstrate that the role of a GT unit as a low-cost electricity producer may conflict with its role as a reserve provider, but through maintaining a proper proportion of idle GT capacities for reserve, the well-being performance of the power system concerned can be significantly improved.
