Expected security constrained reactive power planning
Authors: Karami‐Horestani AliReza , Hamedani Golshan Mohammad Esmail , Monsef Hassan
Published: May 2016

The adequate reactive power resources are expected to maintain system integrity under both normal and post contingency operations. Nowadays, the power systems are leading to high‐risk operating points, hence, the number of probable contingencies, which should be considered in security constrained reactive power planning (SCRPP), has widely increased. However, considering a large number of contingencies in SCRPP is not practically possible. This study presents an index named expected violation index to consider numerous contingencies in SCRPP. At first, a multi‐objective algorithm for the proposed expected SCRPP approach is presented. This novel algorithm uses the probability of each contingency to invest on them more efficiently. Next, it presents a method for selecting candidate buses to install reactive power resources. Then, the effectiveness of the proposed method is analysed using a multi‐objective particle swarm optimisation algorithm on IEEE 30‐bus test system. Finally, a reliability‐based quantitative method is presented for selecting among final Pareto optimal solution. Using the proposed method, the system designers are capable to consider a large number of contingencies in their SCRPPs, to invest more purposefully in reactive power equipment, and to select their most appropriate option among different feasible choices in the optimal Pareto solution.
Reactive power coordinated optimisation method with renewable distributed generation based on improved harmony search
Authors: Sheng Wanxing , Liu Ke‐yan , Liu Yongmei , Ye Xueshun , He Kaiyuan
Published: May 2016

The reactive power coordinated optimisation problem for distribution network (DN) with the integration of renewable distributed generation (DG) is investigated in this study. By actively participating in reactive power control together with an under‐load tap changer and shunt capacitors, DG can operate more effectively in the DN. Non‐dispatchable DG is considered in the coordinated optimisation method. The objective of the proposed reactive power coordinated optimisation method is to minimise active power loss and to decrease the number of switching device operations while maintaining the grid voltage within the allowable range. The optimisation problem is to solve a variable combination including integers and continuous variables, which will formulate a mixed integer non‐linear programming (MINLP) problem. The control variable includes operations of traditional reactive power control devices and the reactive power adjustments of DGs. To solve the MINLP problem, a heuristic searching method, an improved harmony search algorithm is proposed with adaptive parameters process. Numerical tests on a standard 10‐kV distribution system and a real distribution system demonstrate the applicability of the proposed reactive power coordinated optimisation method.
Optimal power factor for optimally located and sized solar parking lots applying quantum annealing
Authors: Rahmani‐andebili Mehdi
Published: May 2016

Investigating optimal value of the power factor for the optimally allocated and sized solar parking lots of the plug‐in electric vehicles (PEVs) based on minimum total cost of the problem over the given planning period is the aim of this study. Covering a parking lot with photovoltaic (PV) panels can keep the PEVs cool, charge their batteries for free, and generate extra energy and deliver it to the grid. Moreover, the inverter installed in the charging station of a parking lot is capable of generating or absorbing reactive power by changing the operating mode of the inverter without any degradation of the PEV's battery. Therefore, the PEVs and the solar parking lots can be applied as the auxiliary sources of active and reactive powers by the local distribution company (DISCO). In this study, in order to achieve realistic results, the economic aspects and technical factors of the system, and also the behavioural model of the PEVs fleet are taken into consideration in the planning problem. Moreover, the stochastic nature of the PEVs behaviour and power of the installed PV panels are modelled in the problem. Herein, the planning problem is solved applying quantum annealing (QA).
Enhanced variable bandwidth progression optimisation model in arterial traffic signal control
Authors: Shirvani Mohamad Javad , Maleki Hamid Reza
Published: May 2016

Bandwidth progression optimisation is a widely used approach for traffic signal coordination along the arterial streets. In this study, a new mixed integer variable bandwidth optimisation model is proposed. In this way, arterial traffic signals are set based on fully acceptable and unacceptable thresholds for each arterial link‐specific bandwidth and green split which are specified by traffic engineer. On the basis of these parameters, a fuzzy membership function is defined for each bandwidth as well as each green split. Then, the proposed bandwidth optimisation model is developed by Bellman–Zade principles of fuzzy decision making. In this model, green splits, junctions’ offsets, cycle length, and left turn phase sequences pattern are simultaneously optimised. By this method, the traffic engineer can balance the arterial green band and opposite movements green splits. The efficiency of the proposed method has been evaluated by several measures of effectiveness compared with classic variable bandwidth and TRANSYT13 software.
Broadband, low‐cost and low cross‐polarisation dual linearly polarised reflectarray antenna
Authors: Mahmoodi Mahboobeh , Chamaani Somayyeh
Published: May 2016

This study attempts to attain a broad bandwidth (BW) from a simple and low cost dual linearly polarised structure. The unit cell is a patch loaded with three concentric slots: a square, a vertical cross and a slant cross, printed on a foam backed dielectric. Required phases can be adjusted by both vertical and slant crosses which provides an extra degree of freedom in phase error and phase sensitivity reduction. The slant cross also improves angular stability of gain and cross‐polarisation. Four reflectarrays (RAs) were designed at 10.7 GHz frequency. RA1 and RA2 utilised only the vertical and slant crosses, respectively, whereas RA2 achieved broader BW due to less sensitivity of slant cross. RA3 used both crosses to get lower phase error. However, due to dissimilarity among cells and uncontrolled phase sensitivity, it was poor in terms of gain and BW. To overcome this issue, in RA4, in addition to phase error and phase sensitivity control diversity, a local similarity is enforced. This array shows 23 dB gain and 3 dB gain BW of 17%. In 3 dB BW, its cross‐polarisation level is −24 dB at boresight and also satisfactory in non‐principal planes.

Fabricated prototypes were measured and compared with simulation and good agreement is obtained for both impedance and radiation characteristics.
Burst‐by‐burst dynamic bandwidth allocation for XG‐PONs
Authors: Gravalos Ilias , Yiannopoulos Kostas , Papadimitriou Georgios , Varvarigos Emmanuel A.
Published: May 2016

The authors propose and evaluate the performance of a dynamic bandwidth allocation algorithm, namely burst‐by‐bUrst dynamic bandwidth allocation (BUDA), which enables the fair and efficient utilisation of the available upstream resources in 10‐Gigabit‐capable passive optical networks (XG‐PONs). The proposed algorithm emulates a bit‐by‐bit burst multiplexing process based on the fair queuing scheduling principle to fairly allocate the available upstream bandwidth among several end‐users with varying traffic demands. The fair queuing approach is well‐suited to the strictly synchronous communication model of XG‐PONs, where fixed duration downstream and upstream frames are utilised to delineate transmissions, and the authors demonstrate via simulations that BUDA achieves low and bounded latency, as well as resource allocation fairness over a set of different traffic loads. Furthermore, BUDA is compared with well‐known bandwidth allocation algorithms and a significant latency and fairness benefit is demonstrated.

Published: May 2016

In the past two decades, many different multilevel converters have been presented. Usually, these comprise a large number of semiconductors. Some converters try to reduce the amount of semiconductors by using some of them for the three phases. This study presents a different approach: a converter where all the switching semiconductors are common for the three phases. This approach reduces the amount of high‐frequency switching semiconductors and can use cheaper semiconductors for low‐frequency switching ones, which may lead to a reduction of the total cost of the converter. Different options are described throughout this study and the advantages and disadvantages of each one of them are discussed. Finally, some simulation results illustrate the correct operation of the proposed new topology.

Published: May 2016

Prompted by technical issues that have arisen due to the widespread deployment of distributed intermittent renewable generators, rapidly rising peak demand and reductions in battery price, the use of battery‐based energy storage systems in power networks is on the rise. While battery‐based energy storage has the potential to deliver technical benefits, the best possible sizing, location and usage govern the financial viability. The objective of this study is twofold. Firstly, a generalised approach is proposed to model network upgrade deferral as a function of load growth rate, renewable generation penetration and peak shave fraction. This model is then used for the formulation of an optimisation problem which benefits from multi‐period power flow analysis to co‐optimise battery size, location, charge/discharge profile for a pre‐specified number of units to be deployed in a given distribution network. The proposed approach is implemented using the generic algebraic modelling system platform and validated on an Australian medium voltage distribution network under multiple practical and potential future scenarios.

This article presents an example of application of a modern test facility conceived for experiments regarding the integration of renewable energy in the power system. The capabilities of the test facility are used to validate dynamic simulation models of wind power plants and their controllers. The models are based on standard and generic blocks. The successful validation of events related to the control of active power (control phenomena in <10 Hz range, including frequency control and power oscillation damping) is described, demonstrating the capabilities of the test facility and drawing the track for future work and improvements.
Optimal allocation of cooperative jamming resource based on hybrid quantum‐behaved particle swarm optimisation and genetic algorithm
Authors: Jiang Haiqing , Zhang Yangrui , Xu Hongyi
Published: May 2016

The multi‐dimension jamming resources allocation (JRA) problem is studied to enhance the jamming effectiveness for the cooperative jammers formation against radar net. The allocation strategies include the methods of allocating jamming resources and the mode selection for the jamming signal. First, jamming resource optimum allocation model is established based on the detection probability of the netted radar fusion centre. Second, a hybrid quantum‐behaved particle swarm optimisation and self‐adjustable genetic algorithm (HQPSOGA) is proposed to optimise the deployment of the jamming resource innovatively with multi‐constrained conditions. Finally, the HQPSOGA is compared with the integer‐value genetic algorithm, standard particle swarm optimisation (PSO) and quantum‐behaved PSO in JRA problem regarding the solution quality, robustness, convergence rate and reliability by a general Monte Carlo simulation. Simulation results show that the proposed method is capable of developing better overall interference capacity efficiently for the jammers formation than any other tested algorithm.
Evaluation of Perfusion Quantification Methods with Ultrasound Contrast Agents in a Machine-Perfused Pig Liver
Authors: Averkiou Michalakis , Keravnou Christina , Izamis Maria , Leen Edward
Published: May 2016

Purpose To evaluate dynamic contrast-enhanced ultrasound (DCEUS) as a tool for measuring blood flow in the macro- and microcirculation of an ex-vivo machine-perfused pig liver and to confirm the ability of DCEUS to accurately detect induced flow rate changes so that it could then be used clinically for monitoring flow changes in liver tumors.

Materials and Methods Bolus injections of contrast agents in the hepatic artery (HA) and portal vein (PV) were administered to 3 machine-perfused pig livers. Flow changes were induced by the pump of the machine perfusion system. The induced flow rates were of clinical relevance (150 – 400 ml/min for HA and 400 – 1400 ml/min for PV). Quantification parameters from time-intensity curves [rise time (RT), mean transit time (MTT), area under the curve (AUC) and peak intensity (PI)] were extracted in order to evaluate whether the induced flow changes were reflected in these parameters.

Results A linear relationship between the image intensity and the microbubble concentration was confirmed first, while time parameters (RT and MMT) were found to be independent of concentration. The induced flow changes which propagated from the larger vessels to the parenchyma were reflected in the quantification parameters. Specifically, RT, MTT and AUC correlated with flow rate changes.

Conclusion Machine-perfused pig liver is an excellent test bed for DCEUS quantification approaches for the study of the hepatic vascular networks. DCEUS quantification parameters (RT, MTT, and AUC) can measure relative flow changes of about 20 % and above in the liver vasculature. DCEUS quantification is a promising tool for real-time monitoring of the vascular network of tumors.

Published: May 2016

Purpose Liver stiffness (LS) has been shown to be of use in chronic liver disease patients but its utility in surgical judgment still needs to be proven. A decision-making approach was applied to evaluate whether LS measurement before surgery of hepatocellular carcinoma (HCC) can be useful in avoiding post-hepatectomy liver failure (PHLF).

Materials and Methods Decision curve analysis (DCA) was applied to 202 HCC patients (2008 – 14) with LS measurement prior to hepatectomy to verify whether the occurrence of PHLF grades B/C should be reduced through a decision-making approach with LS. 

Results Within 90 days of surgery, 4 patients died (2 %) and grades B/C PHLF occurred in 29.7 % of cases. Ascites and/or pleural effusion, treatable with medical therapy, were the most frequent complications. DCA showed that using the “expected utility theory” LS measurement can reduce up to 39 % of cases of PHLF without the exclusion of any patient from surgery that duly undergoes an uncomplicated postoperative course. LS measurement does not add any information to normal clinical judgment for patients with a low (< 10 %) risk of PHLF.

Conclusion LS measurement can determine a reduction of PHLF under “expected utility theory” fulfilment. However, the degree of PHLF can be minor and “risk seeking” individuals can accept such a risk on the basis of surgical benefits.
What constitutes appropriate peer review for interdisciplinary research?
Authors: Bammer Gabriele
Published: May 2016

How can interdisciplinary research proposals be more effectively assessed through peer review? A key issue is to characterize what constitutes appropriate peer review for interdisciplinary research. This is approached by considering four key elements on which evaluations of funding proposals are based: (1) the significance of the topic, (2) the importance and tractability of the research question, (3) the appropriateness of the methods and (4) the competence of the applicants, based on track record. Two major differences between disciplinary and interdisciplinary research emerge: (1) the unknowns that form the basis of research questions and (2) the methods employed. For peer review of interdisciplinary research proposals to become more effective, agreed criteria for assessment by peer review are required and this will only occur if interdisciplinarity is “organized” through colleges of peers and professional associations. This article is published as part of a collection on interdisciplinarity.
Irregular Liesegang-type patterns in gas phase revisited. II. Statistical correlation analysis
Authors: Torres-Guzmán José C. , Martínez-Mekler Gustavo , Müller Markus F.
Published: May 2016

We present a statistical analysis of Liesegang-type patterns formed in a gaseous HCl-NH3 system by ammonium chloride precipitation along glass tubes, as described in Paper I [J. C. Torres-Guzmán et al., J. Chem. Phys. 144, 174701 (2016)] of this work. We focus on the detection and characterization of short and long-range correlations within the non-stationary sequence of apparently irregular precipitation bands. To this end we applied several techniques to estimate spatial correlations stemming from different fields, namely, linear auto-correlation via the power spectral density, detrended fluctuation analysis (DFA), and methods developed in the context of random matrix theory (RMT). In particular RMT methods disclose well pronounced long-range correlations over at least 40 bands in terms of both, band positions and intensity values. By using a variant of the DFA we furnish proof of the nonlinear nature of the detected long-range correlations.
C
–IBI: Targeting cumulative coordination within an iterative protocol to derive coarse-grained models of (multi-component) complex fluids
Authors: de Oliveira Tiago E. , Netz Paulo A. , Kremer Kurt , Junghans Christoph , Mukherji Debashish
Published: May 2016

We present a coarse-graining strategy that we test for aqueous mixtures. The method uses pair-wise cumulative coordination as a target function within an iterative Boltzmann inversion (IBI) like protocol. We name this method coordination iterative Boltzmann inversion (C–IBI). While the underlying coarse-grained model is still structure based and, thus, preserves pair-wise solution structure, our method also reproduces solvation thermodynamics of binary and/or ternary mixtures. Additionally, we observe much faster convergence within C–IBI compared to IBI. To validate the robustness, we apply C–IBI to study test cases of solvation thermodynamics of aqueous urea and a triglycine solvation in aqueous urea.
Influence of anisotropic permeability on convection in porous media: Implications for geological CO2 sequestration
Authors: De Paoli Marco , Zonta Francesco , Soldati Alfredo
Published: May 2016

Solute convection in porous media at high Rayleigh-Darcy numbers has important fundamental features and may also bear implications for geological CO2 sequestration processes. With the aid of direct numerical simulations, we examine the role of anisotropic permeability on the distribution of solutal concentration in fluid saturated porous medium. Our computational analyses span over few decades of Rayleigh-Darcy number and confirm the linear scaling of Nusselt number that was previously found in the literature. In addition, we find that anisotropic permeability γ < 1, i.e., with vertical permeability smaller than horizontal permeability, effectively increases the Nusselt number compared with isotropic conditions. We link this seemingly counterintuitive effect with the occurring modifications to the flow topology in the anisotropic conditions. Finally, we use our data computed for the two-sided configuration (i.e., Dirichlet conditions on upper and lower boundaries) to examine the time evolution of solutal dynamics in the one-sided configuration, and we demonstrate that the finite-time (short-term) amount of CO2 that can be dissolved in anisotropic sedimentary rocks is much larger than in isotropic rocks.
Terahertz spectroscopic polarimetry of generalized anisotropic media composed of Archimedean spiral arrays: Experiments and simulations
Authors: Aschaffenburg Daniel J. , Williams Michael R. C. , Schmuttenmaer Charles A.
Published: May 2016

Terahertz time-domain spectroscopic polarimetry has been used to measure the polarization state of all spectral components in a broadband THz pulse upon transmission through generalized anisotropic media consisting of two-dimensional arrays of lithographically defined Archimedean spirals. The technique allows a full determination of the frequency-dependent, complex-valued transmission matrix and eigenpolarizations of the spiral arrays. Measurements were made on a series of spiral array orientations. The frequency-dependent transmission matrix elements as well as the eigenpolarizations were determined, and the eigenpolarizations were found be to elliptically corotating, as expected from their symmetry. Numerical simulations are in quantitative agreement with measured spectra.

Scrutinizing critical thermodynamic and kinetic factors for glass formation and the glass stability of materials would benefit the screening of the glass formers for the industry of glassy materials. The present work aims at elucidating the factors that contribute to the glass formation by investigating medium-sized molecules of pharmaceuticals. Glass transition related thermodynamics and kinetics are performed on the pharmaceuticals using calorimetric, dielectric, and viscosity measurements. The characteristic thermodynamic and kinetic parameters of glass transition are found to reproduce the relations established for small-molecule glass formers. The systematic comparison of the thermodynamic and kinetic contributions to glass formation reveals that the melting-point viscosity is the crucial quantity for the glass formation. Of more interest is the finding of a rough correlation between the melting-point viscosity and the entropy of fusion normalized by the number of beads of the pharmaceuticals, suggesting the thermodynamics can partly manifest its contribution to glass formation via kinetics.
