The energy efficiency evaluation process of the model is divided into three levels: the first level establishes four energy efficiency evaluation dimensions based on qualitative distribution, the second level determines the comprehensive weight based on entropy weight method(EWM) and analytic hierarchy process(AHP), the third level uses the energy efficiency evaluation scores of each region to analyze the current weakness of energy efficiency of each region and provide a basis for future planning. The model combines the data required for subjective and objective evaluation and overcomes the limitation of traditional single weight method. Through the empirical study on the power grid of several cities in a province, it is verified that the evaluation model has strong application value.","PeriodicalId":223198,"journal":{"name":"2020 5th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115737017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The DC microgrid have various wiring modes, such as unipolar wiring, symmetrical unipolar wiring, and symmetrical bipolar wiring, etc. So, there are many grounding methods for DC microgrid, and no unified specification has been formed at present. The fault current characteristics are quite different under various grounding methods, and the protection configuration and setting are quite different. This paper compares the pole-to-ground voltage characteristics of DC microgrid under various typical grounding modes, and presents a recommended grounding scheme of DC microgrid. Then a simple and practical protection configuration scheme is proposed, which meets the economic requirements of DC microgrid. Simulation results show that the scheme has good selectivity for various fault situations. The research results will provide an important theoretical basis for promoting the formation of a unified design specification for DC microgrids.","PeriodicalId":223198,"journal":{"name":"2020 5th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115752347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently used micro-gas turbine transient model follows the constant speed rotor control, which does not match the real micro-gas turbine that may operate in two speed control modes: constant speed control mode and variable speed control mode. Compared with the constant speed control mode, variable speed control provides higher fuel efficiency. This paper builds a transient model based on the variable speed control mode of a single shaft micro gas turbine. In a micro grid, performance of the micro-gas turbine, particularly the load tracking ability and speed adjustment process under different load, is investigated through PSCAD/EMTDC simulation. Simulation results validate the excellent load tracking ability of the micro gas turbine and demonstrate the satisfactory performance of the micro gas turbine working in variable speed control mode.","PeriodicalId":223198,"journal":{"name":"2020 5th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121028429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It may lose its stability due to the influence of faults which leads to interruptions in supply to the utility customers. Therefore, the utility should take immediate necessary measures to ensure the quality of supply and restored the system to optimal that can satisfy all the constraints of the power system. This research work focuses on joined service restoration and optimization. Service restoration is done through restructuring and optimization is carried out through Stud Krill Herd Algorithm (SKHA). The distribution system optimization is achieved by reconfiguration and capacitor placement. SKHA is utilized for handling reconfiguration and optimal capacitor placement simultaneously. The effectiveness of the proposed strategy is validated by implementing two benchmark case studies namely IEEE 33 Bus Radial Distribution System (RDS) and Taiwan Power Distribution Company (TPDC) System.","PeriodicalId":223198,"journal":{"name":"2020 5th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"600 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127522095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shunt reactor with auxiliary winding system inter-turn protection based on zero sequence differential current is proposed, on the basis of fixed relationship between shunt reactor winding zero sequence current and auxiliary winding zero sequence current when fault occurred outside the zone.

At the same time, it is necessary to consider the issue of achieving low switching frequency and harmonic suppression. In view of the above problems, this paper uses voltage reinjection conversion technology to design a DC voltage conversion circuit on the DC side of a conventional series 12-pulse voltage source converter, and constructs a new multilevel photovoltaic grid-connected converter. The new converter can effectively suppress harmonics so that the ac voltage into the grid can obtain an approximate sinusoidal waveform without filtering. In addition, it can ensure that the main bridge power switches achieve zero voltage switching under 50Hz switching frequency and solve the dynamic voltage equalization problem of the power switches in series, which is easy to realize high voltage and large power. Based on the analysis of the working principle of the converter, the theoretical waveforms of the ac and dc sides of the system are given. A unified coordinated control strategy for maximum power tracking, unit power factor grid-connected power generation and reactive power compensation is designed based on the mathematical model of the system. The simulation model of photovoltaic grid-connected system based on the proposed converter is constructed in PSCAD. Finally, the simulation verifies the feasibility of the converter and the effectiveness of the control strategy.","PeriodicalId":223198,"journal":{"name":"2020 5th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116240440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
