This paper has made in-depth research on power restoration for active distribution network by taking distribution network power balance, the number of DG islands and communication switch influencing factors into consideration. By setting backup communication line equivalent to DG and referring it during decision-making process, the overall scheme superiority improves. The type and control characteristics of DGs are fully investigated in the process of using DG to restore load power. This paper also researched the recovery scheme of island power supply in master-slave control mode by separating DGs into master-slave power source. The concept of two chromosome coding constraints and genome / gene sub block are proposed by adopting improved genetic algorithm to get solution and combining active distribution network structure and master-slave control mode when separating islands. It helps to realize avoiding invalid solutions as the cross and mutation operations between chromosomes are completely based on genome. Finally, simulation has been made to verify the validity of the method proposed with 3 feeder lines and 7 DGs.","PeriodicalId":123761,"journal":{"name":"2017 2nd International Conference on Power and Renewable Energy (ICPRE)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115488965","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}

In this paper, for the purpose of meeting the requirement that wind farm providing reactive power to the system under the condition of a short circuit fault occurring on collector lines, a short current circuit calculation model and formula of the DFIG with a LVRT strategy with continuous excitation is established and proposed. Based on Matlab/Simulink, the model of wind farm connecting to the power system is established, by which the proposed short-circuit calculation model is verified correctly. Based on the short-circuit calculation model, the contribution of adjacent wind generators' feeding currents is studied by setting the system capacity, scale of wind farm and fault location as independent variables. From the results of simulation and calculation, with the enlarging scale of wind farms, it is essential for the current protection to take short circuit current through non-fault lines into consideration, moreover, the setting value of current protection is required to consider the actual conditions of the DFIGs in operation and adaptive protection scheme could be considered.","PeriodicalId":123761,"journal":{"name":"2017 2nd International Conference on Power and Renewable Energy (ICPRE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117077299","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 system consists of two parts: the series DC-DC converter part which realizes the maximum power output of the PV system and the establishment of the high voltage DC bus, and the MMC which realizes the high voltage and high power inverter. In this paper, we paid close attention on the operation principle of modular multilevel converter. Much work had been done to establish the switching state space model based on MMC and AC small-signal model. We put forward a dual-loop three-phase access strategy to grid based on carrier phase-shifted sinusoidal pulse width modulation technique to realize the significant degradation decoupling of modular multilevel converter model, in which MMC outer loop is subjected to the voltage while inner loop is subjected to the current. In this paper, an MMC simulation system with 4kV direct current bus and 5 level voltage is modeled to test the feasibility. And the stability and rapid response of the simulation model is outstanding.","PeriodicalId":123761,"journal":{"name":"2017 2nd International Conference on Power and Renewable Energy (ICPRE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130295520","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}
