Firstly, the influence of virtual inertia and damping on system dynamic performance is analyzed based on the frequency and power curves. Secondly, considering the allowable maximum frequency change rate and the energy storage discharge characteristics, the lower and upper ranges of inertia are determined. Then the fuzzy rules are designed for the proposed VSG fuzzy control strategy, which can improve the microgrid stability via flexibly changing the system inertia and damping.

The remote backup power automatic throw-in can effectively solve the power supply reliability of the serial power grid connection, but limited by communication, the remote backup power automatic throw-in is rarely used in the medium and low voltage power grid. This paper provides a principle and implementation of remote backup power automatic throw-in of substation with multiple-communication modes. By setting a wireless router in each remote backup power automatic throw-in device, The router realizes the point-to-point communication of the remote backup power automatic throw-in device by using the generic routing encapsulation(GRE) tap mode, thus realizing the information interaction function of the substation remote backup power automatic throw-in device with multiple-communication modes. The simulation model built in RTDS verifies that the proposed remote backup power automatic throw-in device with multiple communication modes is feasible. This method does not need to change the original software and hardware of remote backup power automatic throw-in device, avoids the problem that the existing technical scheme is easily limited by communication, makes the remote backup power automatic throw-in device more convenient, reliable and simple in structure, and greatly improves the possibility of application in medium and low voltage power grids.","PeriodicalId":201727,"journal":{"name":"2022 Asia Power and Electrical Technology Conference (APET)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125960918","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}

This paper studies an integrated management method called virtual power plant (VPP), which can integrate dispersed distributed energy through aggregators, and operate through a central controller. Then, established a VPP model with PV-battery system, power storage constraints, power balance constraints, power transfer limits to study the change of power generation and power flow and propose an electricity tariff scheme by calculating the local marginal price (LMP) which obtained by computing the Lagrange multipliers for different constraints. In this way, real-time electricity price updates can be controlled and send to users at each corresponding time slot. This paper also simulates this process and analyzes the result, the average marginal price that users with different property need to pay under VPP is compared, and the impact of changing marginal resources on the results is also discussed. The results show that VPP effectively reduces the marginal cost of the power plant, and all participants will get benefits, which reflecting the maximization of social benefits.","PeriodicalId":201727,"journal":{"name":"2022 Asia Power and Electrical Technology Conference (APET)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134235831","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}
