To further investigate the influence of photovoltaic integrating into distributed networks, the photovoltaic power generation model is built in detail and the characteristics of single-unit photovoltaic under different weather is analyzed. The characteristic Analysis of regional distributed photovoltaic is also conducted based on real-world data. The PV-load consumption factor of different users is analyzed and a practical procedure for hosting capacity analysis proposed based on different consumption factors.","PeriodicalId":201727,"journal":{"name":"2022 Asia Power and Electrical Technology Conference (APET)","volume":"52 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":"130458636","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}

However, with the large-scale integration of renewable energy and the randomness of load consumption, there are more strict requirements for the power flow equilibrium of power system. Therefore, it becomes necessary to study the analysis and control methods of such equilibrium. The unified power flow controller (UPFC) is introduced to balance the power flow distribution in the stochastic context by adjusting the control parameters. In addition, the equilibrium degree of distribution can be used to quantify the power flow equilibrium of the lines, the probabilistic results of which are determined by means of the probabilistic power flow calculation based on Latin hypercube simulation method (LHS). The results of IEEE39 Test System indicate that the power flow distribution of the transmission section is more balanced after the UPFC is configured.","PeriodicalId":201727,"journal":{"name":"2022 Asia Power and Electrical Technology Conference (APET)","volume":"39 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":"132013247","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 is of great significance to reveal the influence of VSC-HVDC grid-connected on the transient stability of power grid. The external power characteristics of VSC-HVDC are equivalent to time-varying ground admittance. Based on the extended equal area criterion (EEAC), the influence of VSC-HVDC grid-connected admittance on the self-admittance and mutual admittance of synchronous generator internal potential node is studied, the quantitative relationship between the VSC-HVDC grid-connected admittance and the change of transient power angle stability margin is deduced. Based on this, the influence law of the active and reactive power on the transient stability of the power grid is quantitatively analyzed. Finally, the correctness of the conclusion is verified by simulation.","PeriodicalId":201727,"journal":{"name":"2022 Asia Power and Electrical Technology Conference (APET)","volume":"1 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":"125867084","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}
