PEMANFAATAN GOOGLE TRANSLATOR SEBAGAI MEDIA PEMBELAJARAN PADA TERJEMAHAN TEKS BERITA ASING
Authors: Al-Ayubi Muhammad Shalehuddin
Published: September 2018

Kehadiran google terjemahan merupakan salah satu media yang bisa memudahkan pembelajar untuk menerjemahkan berbagai jenis teks kedalam bahasa yang diinginkan. Pembelajaran Bahasa Inggris bisa menjadi mudah dengan hadirnya media penerjemah yanng populer dengan nama google translate. Namun, seringkali pembelajar menemukan kesalahan dan kejanggalan dalam terjemahan teks yang dimasukkan. Melalui penelitian ini, kejanggalan itu dijawab dengan analisis terhadap keberterimaan terjemahan teks berita yang diterjemahkan dengan google terjemahan, dan dibandingkan dengan hasil terjemahan dari sebuah kantor berita. Teks berita diambil sebagai teks umber karena teks berita merupakan jenis teks yang umum dibaca masyarakat, bahkan bisa menjadi salah satu materi dalam pembelajaran kosa kata bahasa inggris. Dalam dunia penerjemahan, ada dua bentuk kesepadanan yang menjadi acuan, yaitu kesepadanan formal dan kesepadanan dinamis. Masing-masing bentuk kesepadanan memiliki kriteria tersendiri yang harus dimiliki oleh sebuah teks terjemahan. Penelitiaan ini adalah penelitian deskriptif kualitatif untuk satu kasus. Data objektif yang dianalisis adalah naskah teks terjemahan pada berita di media online dari kantor berita asing yang dijadikan sebagai teks sumber.Teknik pengambilan sample berita dilakukan secara acak. Dari hasil penelitian ditemukan fakta bahwa bentuk kesepadanan formal hampir bisa dicapai oleh teks terjemahan google translate, namun berdasarkan parameter dan skala keberterimaan yang peneliti gunakan, dapat disimpulkan bahwa teks terjemahan google tidak tergolong dalam teks terjemahan dengan keberterimaan yang baik. Sedangkan teks terjemahan dari jurnalis kompas.com sebagai pembanding, ditemukan fakta bahwa meskipun tidak mencapai kesepadanan formal, terjemahan jurnalis kompas masuk ke dalam kategori teks terjemahan dengan keberterimaan yang baik.

Published: September 2018

ABSTRAKSistem kurikulum pendidikan di sekolah mengintegrasikan penanaman nilai-nilai pendidikan karakter dalam setiap aktifitas pembelajaran. Hal ini tentunya dapat menjadi bekal yang sangat berharga berupa nilai-nilai luhur yang akan sangat berguna ketika siswa benar-benar terjun ke dalam kehidupan bermasyarakat. Pendidikan karakter pada pembelajaran bahasa asing sangat erat kaitannya karena latar belakang bahasa asing yang dipelajari maupun siswa sebagai subjek belajar tentunya berbeda. Selain itu, kesulitan siswa dalam mempelajari materi membaca, khususnya analisis gramatika pun menjadi perhatian guru. Tidak hanya dalam kognitif saja, guru juga perlu memerhatikan aspek kecerdasan siswa yang berbeda, atau kecerdasan majemuk yang menuntut guru untuk memberikan perlakuan yang sesuai. Sehingga guru perlu menerapkan berbagai teknik pembelajaran yang dapat menggugah semangat siswa meskipun harus mempelajari materi bertingkat kesulitan tinggi. Salah satu cara yang dapat diterapkan adalah dengan penggunaan media korpus linguistik berbasis web yang bernama The Quranic Arabic Corpus dan penerapan teknik pembelajaran Mission Walls. Penelitian ini menggunakan metode analisis kajian pustaka, dengan menganalisis beberapa karya ilmiah yang merupakan hasil laporan penelitian penggunaan media korpus linguistik dan penerapan Mission Walls dalam rangka penguatan pendidikan karakter dan kecerdasan majemuk. Hasilnya adalah pendidikan karakter dan pembelajaran berbasis kecerdasan majemuk menjadi penting dan integrasi web korpus dan Mission Walls dapat diterapkan. Keseluruhan Mission Walls mengandung 11 nilai karakter, yakni jujur dan rasa ingin tahu, toleransi, kerja keras, tanggung jawab, kreatif, dan demokratis, menghargai prestasi, komunikatif, dan gemar membaca. Kesimpulannya, sangat memungkinkan bagi guru untuk menggunakan media berbasis web, penerapan berbagai teknik pembelajaran inovatif dan megintegrasikannya dengan penguatan pendidikan karakter dan mengasah kecerdasan majemuk siswa.

Published: September 2018

Background: Post-operative outcome of extradural haematoma (EDH) patients depends on the time interval of operation.Objectives: The purpose of the present study was to evaluate the role of time interval and surgical intervention in EDH.Methodology: This interventional study was carried out in the Department of Neurosurgery at Dhaka Medical College and Hospital, Dhaka, Bangladesh from July 2001 to July 2003 for a period of two (02) years. Patients with the history of head trauma admitted in Neurosurgery unit of Dhaka Medical College and Hospital which were being diagnosed as EDH both clinically and radiologically were included as study population. All patients were treated surgically and haematoma was evacuated. Outcome regarding neurological status, functional recovery, associated morbidity and mortality were assessed in each case as per Glasgow Outcome Scale and was compared between the two groups of patients who were treated surgically within 3rd day and 4th to 7th day after infliction of injury. The study population was devided into 4 groups on the basis of the consciousness level on admission of the patients. The EDH patietns who had GCS <5, 5 to 8, 9 to 12 and 13 to 15 were categorized as group I, II, III and IV respectively. On the basis of pre operative time interval, surgical intervention was done within 3 days of injury and from 4th to 7th day of injury. Craniotomy and craniectomy were done depending on patient’s condition and situation of haematoma.Result: A total 63 patients were included. During admission out of 63 patients majority of the patients were in the group III which was 29(46%) cases. During pre-operqative period out of 63 patients majority of the patients were in the group III which was 30(47.6%) cases. Out of 63 cases a total number of 40 cases were performed the surgery within 72 hours and the rest 23 patients were from 4th day to 7th day of injury. In group I at 8th POD, 3 death cases were recorded at 3rd day operation group and 2 cases at 4th to 7th cases. In group IV at 8th POD follow up good recovery was reported in 6 cases at 3rd day and 3 cases at 4th to 7th day. In group I after 1 month, 3 death cases were recorded at 3rd day operation group and 2 cases at 4th to 7th cases. In group IV after 1 month follow up good recovery was reported in 6 cases at 3rd day and 3 cases at 4th to 7th day; however, moderate disability was reported in 2 cases at 4th to 7th day.Conclusion: In conclusion mortality rate is reduced in patients with EDH who are treated in the earliest possible time after head injuryJournal of National Institute of Neurosciences Bangladesh, 2018;4(1): 33-39
Monomelic Amyotrophy (Hirayama Disease) with Proximal Upper Limb Involvement: A Case Report
Authors: Mamun Abdullah Al , Sheikh Mirazul Islam , Bala Chandra Shekhar , Islam Tariqul , Alam Md Badrul
Published: September 2018

Monomelic amyotrophy is an uncommon, benign, unilateral disorder of the lower motor neurons, affecting predominantly the hand and forearm muscles. A 28-year-old man presented with insidious-onset, slowly progressive, unilateral weakness and atrophy of his shoulder girdle and arm muscles on right side. A neurological examination revealed weakness and atrophy in his right deltoid, infraspinatus, supraspinatus and triceps muscles. Electromyography demonstrated an active and chronic neurogenic pattern affecting his right C5 and C6 myotomes; magnetic resonance imaging of his cervical spine showed snake eye appearance within the spinal cord. Upper limb proximal form of monomelic amyotrophy is a rare clinical entity with a wide differential diagnosis. Physicians, especially neurologists, should be familiar with this benign condition to avoid inappropriately labeling patients as having amyotrophic lateral sclerosis and other disorders with less favorable outcomes.Journal of National Institute of Neurosciences Bangladesh, 2018;4(1): 63-66
Breeding of the Dormant Thermosensitive Genic Male-Sterile Lines of Early Rice to Overcome Pre-Harvest Sprouting of the Hybrid Seeds
Authors: Chen Xiaoyu , Tian Yun , Lu Xiangyang
Published: September 2018

The pollen development of male-sterile lines should be conducted during the high temperature season to ensure the sterility of male-sterile line pollen and the safety of hybrid seed production in the breeding of thermosensitive genic male-sterile (TGMS) lines of early rice. However, the mature hybrid rice seeds are prone to pre-harvest sprouting (PHS) during hot, rainy days, which leads to the decrease of hybrid rice seed quality or a loss of utilization value. In this study, with an aim to bring a dormancy trait from the dormant genotype to the current low-dormant TGMS lines, a common wild rice “Chaling” (Oryza rufipogon), which has strong seed dormancy, a large black stigma, and a high exsertion rate, was hybridized with the early rice TGMS line “Zhu 1S,” which often exhibits PHS. After screening for early maturing and seed dormancy, the early rice “Yezao S” and “Yezhuzao S,” with the characteristic of seed dormancy, were selected. The critical temperature of high temperature sterility for these two male-sterile lines was below 23.5 °C. The stigma of “Yezao S” was black and its exsertion rate was 79.9%, while “Yezhuzao S” had a colorless stigma with an exsertion rate of 76.8%. The expression of the genes OsNCEDs in “Yezao S” and “Yezhuzao S” were significantly higher than that in “Zhu 1S” the 15th day after heading, and the abscisic acid (ABA) content was also higher than that of “Zhu 1S” the 20th day after heading. The results indicated that introducing the dormancy characteristics from wild rice “Chaling” into the early rice TGMS lines was an effective way to prevent PHS.
Relationship between Maternal and First Year of Life Dispensations of Antibiotics and Antiasthmatics
Authors: Fossum Guro Haugen , Lindbæk Morten , Gjelstad Svein , Kværner Kari J.
Published: September 2018

Antibiotics are the most frequent prescription drugs used by pregnant women. Our objective was to investigate if the dispensation of antibiotics and antiasthmatics in children less than 1 year of age is associated with prenatal antibiotic exposure. A secondary aim was to explore the incidence of dispensed antibiotics in pregnancy and dispensed antibiotics and antiasthmatics in children. We conducted an observational study using the Peer Academic Detailing study database to select patients eligible for match in the Medical Birth Registry of Norway, a total of 7747 mother-and-child pairs. Details on antibiotic and antiasthmatic pharmacy dispensations were obtained from the Norwegian Prescription Database. One quarter (1948 of 7747) of the mothers in the study had been dispensed antibiotics during pregnancy. In their first year of life, 17% (1289) of the children had had an antibiotic dispensation, 23% (1747) an antiasthmatic dispensation, and 8% (619) of the children had had both. We found a significant association between dispensed antibiotics in pregnancy and dispensed antibiotics to the child during their first year of life; OR = 1.16 (95% CI: 1.002–1.351). The association was stronger when the mothers were dispensed antibiotics at all, independent of the pregnancy period; OR = 1.60 (95% CI: 1.32–1.94). We conclude that the probability for dispensation of antibiotics was increased in children when mothers were dispensed antibiotics, independent of pregnancy. Diagnostic challenges in the very young and parental doctor-seeking behavior may, at least in part, contribute to the association between dispensations in mothers and children below the age of one year.
Remote Monitoring and Evaluation of Damage at a Decommissioned Nuclear Facility Using Acoustic Emission
Authors: Abdelrahman Marwa , ElBatanouny Mohamed , Dixon Kenneth , Serrato Michael , Ziehl Paul
Published: September 2018

Reinforced concrete systems used in the construction of nuclear reactor buildings, spent fuel pools, and related nuclear facilities are subject to degradation over time. Corrosion of steel reinforcement and thermal cracking are potential degradation mechanisms that adversely affect durability. Remote monitoring of such degradation can be used to enable informed decision making for facility maintenance operations and projecting remaining service life. Acoustic emission (AE) monitoring has been successfully employed for the detection and evaluation of damage related to cracking and material degradation in laboratory settings. This paper describes the use of AE sensing systems for remote monitoring of active corrosion regions in a decommissioned reactor facility for a period of approximately one year. In parallel, a representative block was cut from a wall at a similar nuclear facility and monitored during an accelerated corrosion test in the laboratory. Electrochemical measurements were recorded periodically during the test to correlate AE activity to quantifiable corrosion measurements. The results of both investigations demonstrate the feasibility of using AE for corrosion damage detection and classification as well as its potential as a remote monitoring technique for structural condition assessment and prognosis of aging structures.

Published: September 2018

In electrical engineering problems, bio- and nature-inspired optimization techniques are valuable ways to minimize or maximize an objective function. We use the root tree algorithm (RTO), inspired by the random movement of roots, to search for the global optimum, in order to best solve the problem of overcurrent relays (OCRs). It is a complex and highly linear constrained optimization problem. In this problem, we have one type of design variable, time multiplier settings (TMSs), for each relay in the circuit. The objective function is to minimize the total operating time of all the primary relays to avoid excessive interruptions. In this paper, three case studies have been considered. From the simulation results, it has been observed that the RTO with certain parameter settings operates better compared to the other up-to-date algorithms.
Determination of Permeability and Inertial Coefficients of Sintered Metal Porous Media Using an Isothermal Chamber
Authors: Zhong Wei , Ji Xiang , Li Chong , Fang Jiwen , Liu Fanghua
Published: September 2018

Sintered metal porous media are widely used in a broad range of industrial equipment. Generally, the flow properties in porous media are represented by an incompressible Darcy‒Forchheimer regime. This study uses a modified Forchheimer equation to represent the flow rate characteristics, which are then experimentally and theoretically investigated using a few samples of sintered metal porous media. The traditional steady-state method has a long testing time and considerable air consumption. With this in mind, a discharge method based on an isothermal chamber filled with copper wires is proposed to simultaneously determine the permeability and inertial coefficient. The flow rate discharged from the isothermal chamber is calculated by differentiating the measured pressure, and a paired dataset of pressure difference and flow rate is available. The theoretical representations of pressure difference versus flow rate show good agreement with the steady-state results. Finally, the volume limit of the isothermal chamber is addressed to ensure sufficient accuracy.
Effect of Sediment Concentration on Hydraulic Characteristics of Energy Dissipation in a Falling Turbulent Jet
Authors: Gou Wenjuan , Li Huiping , Du Yunyi , Yin Hongxia , Liu Fang , Lian Jijian
Published: September 2018

The effect of sediment on the hydraulics of jet energy dissipation is an urgent issue for high dams built on sediment-laden rivers. Accordingly, flume experiments were conducted using a ski-jump type energy dissipator in flows of four sediment concentrations (0 kg/m3, 50 kg/m3, 150 kg/m3, and 250 kg/m3) to determine the effects on discharge, flow regime, and hydrodynamic pressure in a plunge pool. The results demonstrate that the effect of sediment on discharge is constant, regardless of sediment concentration, when compared to fresh water. The width of the nappe decreased with increasing concentrations of sediment. The length of the jet trajectory increased with upstream water head. The time-averaged pressure and fluctuation pressure both exhibited peaks, describing the impact of the jet on the bottom of the plunge pool. The maximum time-averaged pressure and maximum fluctuating pressure both noticeably increased with upstream water head and slightly increased with sediment concentration for a given flow condition. The results also demonstrated that the dominant frequency of fluctuation trends to lower values, and that both the fluctuating energy and vortex scale increase with increasing sediment concentrations due to increased viscosity. These findings can be used to improve energy dissipation in dams on sediment-laden rivers.

Authors: Chen Wengang , Xiu Wenzheng , Shen Jin , Zhang Wenwen , Xu Min , Cao Lijun , Ma Lixiu
Published: September 2018

By using different weights to deal with the autocorrelation function data of every delay time period, the information utilization of dynamic light scattering can be obviously enhanced in the information-weighted constrained regularization inversion, but the denoising ability and the peak resolution under noise conditions for information-weighted inversion algorithm are still insufficient. On the basis of information weighting, we added a penalty term with the function of flatness constraints to the objective function of the regularization inversion, and performed the inversion of multiangle dynamic light scattering data, including the simulated data of bimodal distribution particles (466/915 nm, 316/470 nm) and trimodal distribution particles (324/601/871 nm), and the measured data of bimodal distribution particles (306/974 nm, 300/502 nm). The results of the inversion show that multiple-penalty-weighted regularization inversion can not only improve the utilization of the particle size information, but also effectively eliminate the false peaks and burrs in the inversed particle size distributions, and further improve the resolution of peaks in the noise conditions, and then improve the weighting effects of the information-weighted inversion.
Dynamic Optimization Using Local Collocation Methods and Improved Multiresolution Technique
Authors: Zhao Jisong , Shang Teng
Published: September 2018

Dynamic optimization has wide applications in scientific and industrial researches. Multiresolution techniques provide an efficient way to solve dynamic optimization problems but have some disadvantages. An improved multiresolution technique is developed in this paper to overcome these disadvantages. The proposed technique consists of local collocation methods and a multiresolution-based mesh refinement method. New, generalized dyadic meshes are proposed to overcome the dyadic limitation, and the mesh refinement method is improved so that it can start with the coarsest generalized dyadic mesh. Additionally, the proposed technique involves a mesh refinement algorithm to remove the redundant mesh points in the constant control regions by analyzing the control slopes. The technique is applied to three chemical process control optimization problems and compared with other methods to demonstrate its effectiveness. Numerical results show that the proposed technique can solve chemical process control optimization problems accurately and efficiently and has advantages over other methods.
Neurodegenerative Diseases: Regenerative Mechanisms and Novel Therapeutic Approaches

Regeneration refers to regrowth of tissue in the central nervous system. It includes generation of new neurons, glia, myelin, and synapses, as well as the regaining of essential functions: sensory, motor, emotional and cognitive abilities. Unfortunately, regeneration within the nervous system is very slow compared to other body systems. This relative slowness is attributed to increased vulnerability to irreversible cellular insults and the loss of function due to the very long lifespan of neurons, the stretch of cells and cytoplasm over several dozens of inches throughout the body, insufficiency of the tissue-level waste removal system, and minimal neural cell proliferation/self-renewal capacity. In this context, the current review summarized the most common features of major neurodegenerative disorders; their causes and consequences and proposed novel therapeutic approaches.

The hydroprocessing of substituted naphthalenes and light cycle oil (LCO) over bimetallic Ni-W-S and Ni-Mo-S catalysts that were obtained by decomposition of [N(n-Bu)4]2[Ni(MeS4)2] (Me = W, Mo) complexes in situ in the pores of mesoporous aromatic frameworks (PAFs) during the reaction, was studied. The promotion of acid-catalyzed processes by PAF-AlCl3, synthesized by impregnation of a PAF with AlCl3 from its toluene solution, was investigated. It has been found that Ni-W-S catalytic systems were more active in the hydrodearomatization reactions, while Ni-Mo-S catalytic systems were more active in hydrodesulfurization and hydrocracking reactions. The introduction of sulfur into the reaction medium enhanced the activity of the catalysts and the presence of PAF-AlCl3 led to an acceleration of the hydrocracking processes.

Zucchini (Cucurbita pepo L.), extensively cultivated in temperate areas, belongs to the Cucurbitaceae family and it is a species with great economic value. One major threat related to zucchini cultivation is the damage imposed by the cotton/melon aphid Aphis gossypii Glover (Homoptera: Aphididae). We performed RNA-sequencing on cultivar “San Pasquale” leaves, uninfested and infested by A. gossypii, that were collected at three time points (24, 48, and 96 h post infestation). Then, we combined all high-quality reads for de novo assembly of the transcriptome. This resource was primarily established to be used as a reference for gene expression studies in order to investigate the transcriptome reprogramming of zucchini plants following aphid infestation. In addition, raw reads will be valuable for new experiments based on the latest bioinformatic tools and analytical approaches. The assembled transcripts will serve as an important reference for sequence-based studies and for primer design. Both datasets can be used to support/improve the prediction of protein-coding genes in the zucchini genome, which has been recently released into the public domain.

A novel qualitative point-of-care test of activated matrix metalloproteinase-8 (aMMP-8) using noninvasive oral rinse sampling procedures has been developed for the early detection of collagen breakdown indicating periodontal tissue destruction. The main object of this study was to assess the reliability of the test in a low-income setting to identify participants with history of periodontal destruction detected as alveolar bone loss (ABL) in radiographs. This cross-sectional study included 486 women who had recently delivered in rural Malawi. The aMMP-8 test and dental panoramic radiographs were taken within 48 h of delivery. The performance of the test in comparison to radiological examinations was tested by following the standards for reporting of diagnostic accuracy studies protocol (STARD) with respective statistical measures and 95% confidence intervals. From the 486 eligible participants, 461 mothers with complete data, aged from 15 to 46 years (mean 24.8, SD 6.0) were included in the analysis. ABL was identified in 116 of 461 participants. There was 56% agreement between the aMMP-8 test results and detected ABL (yes or no) in radiographs. Calculated sensitivity of the test was 80% (72–87%), specificity 48% (43–54%), positive predictive value 34% (31–37%), negative predictive value 88% (83–91%), positive likelihood ratio 1.55 (1.35–1.77), and negative likelihood ratio 0.41(0.28–0.60). The aMMP-8 test sensitivity and negative predictive value to identify the ABL cases were relatively high, but there was additionally a high rate of test-positive results in participants without ABL, especially in young mothers, leading to low overall agreement between the test results and radiological bone loss. Further longitudinal studies are needed to examine if the test positive subjects are in risk of future bone loss before the detectable signs of periodontitis in radiographs.
Regulation of Sphingolipid Metabolism by MicroRNAs: A Potential Approach to Alleviate Atherosclerosis
Authors: Jahangir Zainab , Bakillah Ahmed , Iqbal Jahangir
Published: September 2018

The rapidly expanding field of bioactive lipids is exemplified by the many sphingolipids, which are structurally and functionally diverse molecules with significant physiologic functions. These sphingolipids are main constituents of cellular membranes and have been found associated with plasma lipoproteins, and their concentrations are altered in several metabolic disorders such as atherosclerosis, obesity, and diabetes. Understanding the mechanisms that regulate their biosynthesis and secretion may provide novel information that might be amenable to therapeutic targeting in the treatment of these diseases. Several sphingolipid synthesis genes have been targeted as potential therapeutics for atherosclerosis. In recent years, significant progress has been made in studying the role of microRNAs (miRNAs) in lipid metabolism. However, little effort has been made to investigate their role in sphingolipid metabolism. Sphingolipid biosynthetic pathways involve various enzymes that lead to the formation of several key molecules implicated in atherosclerosis, and the identification of miRNAs that regulate these enzymes could help us to understand these complex pathways better and may prove beneficial in alleviating atherosclerosis.
A Plug and Play IoT Wi-Fi Smart Home System for Human Monitoring

Published: September 2018

The trend toward technology ubiquity in human life is constantly increasing and the same tendency is clear in all technologies aimed at human monitoring. In this framework, several smart home system architectures have been presented in literature, realized by combining sensors, home servers, and online platforms. In this paper, a new system architecture suitable for human monitoring based on Wi-Fi connectivity is introduced. The proposed solution lowers costs and implementation burden by using the Internet connection that leans on standard home modem-routers, already present normally in the homes, and reducing the need for range extenders thanks to the long range of the Wi-Fi signal. Since the main drawback of the Wi-Fi implementation is the high energy drain, low power design strategies have been considered to provide each battery-powered sensor with a lifetime suitable for a consumer application. Moreover, in order to consider the higher consumption arising in the case of the Wi-Fi/Internet connectivity loss, dedicated operating cycles have been introduced obtaining an energy savings of up to 91%. Performance was evaluated: in order to validate the use of the system as a hardware platform for behavioral services, an activity profile of a user for two months in a real context has been extracted.
Unit-Cell-Based Domain Decomposition Method for Efficient Simulation of a Truncated Electromagnetic Bandgap Structure in High-Speed PCBs
Authors: Kim Myunghoi
Published: September 2018

In this paper, we present a unit-cell-based domain decomposition method (UC-DDM) for rapid and accurate simulation of predicting the parallel plate noise (PPN) suppression of a truncated electromagnetic bandgap (EBG) structure in high-speed printed circuit boards (PCBs). The proposed UC-DDM divides the analysis domain of the truncated EBG structure into UCs as sub-domains. Solving a sub-domain is based on a novel UC model, yielding an analytical expression for the impedance parameter (Z-parameter) of the UC. The novel UC model is derived using a spatial decomposition technique, which results in the modal decomposition of quasi-transverse electromagnetic (TEM) and transverse magnetic (TM) modes. In addition, we analytically derive a impedance-parameter recombination method (ZRM) to obtain the analytical solution of a finite EBG array from the sub-domain results. The proposed UC-DDM is verified through comparison with full-wave simulation results for various EBG arrays. Comparison between the UC-DDM and a full-wave simulation of a truncated EBG structure reveals that a substantial improvement in computation time with high accuracy is achieved. It is demonstrated that the simulation time of the proposed method is only 0.1% of that of a full-wave simulation without accuracy degradation.
VSG Stability and Coordination Enhancement under Emergency Condition

Published: September 2018

Renewable energy sources are integrated into a grid via inverters. Due to the absence of an inherent droop in an inverter, an artificial droop and inertia control is designed to let the grid-connected inverters mimic the operation of synchronous generators and such inverters are called virtual synchronous generators (VSG). Sudden addition, removal of load or faults in the grid causes power and frequency oscillations in the grid. The steady state droop control of VSG is not effective in dampening such oscillations. Therefore, a new control scheme, namely bouncy control, has been introduced. This control uses a variable emergency gain, to enhance or reduce the power contribution of individual VSGs during a disturbance. The maximum power contribution of an individual VSG is limited by its power rating. It has been observed that this control, successfully minimized the oscillation of electric parameters and the power system approached steady state quickly. Therefore, by implementing bouncy control, VSGs can work in coordination to make the grid more robust. The proposed controller is verified through Lyapunov stability analysis.
