To analyze the dynamic of the PMSG during grid disturbances, its steady-state operating condition needs to be firstly solved. It has been verified that initialization to the PMSG needs to add the stator voltage or current orientation constraint. Different steady-state solutions are yielded depending on adopted orientation constraint. Considering that the small signal stability analysis is affected by the initialization to the steady-state condition, in this paper, the small signal analysis results are compared with different orientations adopted to solve the power flow of the PMSG. Considering the active power dispatch operation mode of PMSG, the steady-state solutions with different orientations are obtained. The small signal stability analysis is carried out based on the different power flow solutions, and the conclusions obtained from the comparison results are verified based on simulations of wind speed disturbance scenarios.","PeriodicalId":417862,"journal":{"name":"2021 IEEE Sustainable Power and Energy Conference (iSPEC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126057379","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 traditional cooperative control system can no longer meet the needs of the overall perception of the renewable energy frequency changes, and the traditional emergency control strategy of cutting feed line and generator is difficult to apply. In order to take into account the frequency stability problem and operation economy of renewable energy high-permeability transmission grid, the existing renewable energy is actively involved in the frequency regulation of the system to alleviate the difficulty of frequency regulation of renewable energy high permeability transmission grid. The scheme of “active inertia support of renewable energy sources, coordinated control of renewable energy stations, self-adaptive control of power grid” is proposed. A new cooperative control system suitable for renewable energy high-permeability power grid is studied to realize the real-time state monitoring of renewable energy frequency change and the adaptive switching of control strategy. The experiment verifies the collaborative control system proposed in this paper. Through the power down-regulation test of renewable energy stations, the results show that the control system can respond to power changes in a timely manner, control the regulation time at about milliseconds, and control error is in a small range, which verifies the effectiveness of the collaborative control system.","PeriodicalId":417862,"journal":{"name":"2021 IEEE Sustainable Power and Energy Conference (iSPEC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125691662","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}

Based on this distribution characteristics, this paper proposes a grounding fault section location method based on Tanimoto similarity. Firstly, the transient zero-sequence current at each detection point of the fault line is collected and the amplitude sequence is formed. Then, the Tanimoto similarity between adjacent detection point sequences is calculated. By comparing each calculated value with the threshold value, the fault section with the least similarity and the value less than the threshold is the fault section. The realization flow of locating method is presented for multi-branch line structure and different fault locations. Finally, PSCAD/EMTDC software is used to simulate the fault scenarios under different fault locations and transition resistances, and the results demonstrate the effectiveness of the proposed locating method.","PeriodicalId":417862,"journal":{"name":"2021 IEEE Sustainable Power and Energy Conference (iSPEC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126811389","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 order to conduct APF simulation with higher efficiency, a configurable packaging modeling method for the topology structures and control strategies of APF is developed. First, several topologies of APF as well as their corresponding control strategies are studied and modeled with PSCAD-EMTDC. Then, configurable modeling packages of power grid, load with harmonic current injection and APF are proposed and developed respectively. Finally, a series of simulation studies on the aforementioned modelling packages are implemented. Simulation results show that the APF packaging module matches the functional characteristics of the device and can compensate the harmonic current in the system. APF encapsulation module can significantly improve the modeling efficiency of simulation studies. Researchers can analyze the effects and characteristics of APFs when connected to a system without having to focus too much on technical details of the APF circuit topology and control strategy.","PeriodicalId":417862,"journal":{"name":"2021 IEEE Sustainable Power and Energy Conference (iSPEC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114908053","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}
