This paper firstly analyzes issues relevant to PFR in high-proportion clean energy (HPCE) system, including status of PFR in actual power grid with HPCE and necessity for wind power to extensively participate in PFR. Then, a system frequency response (SFR) model with multienergy is built, and a process for setting PFR parameters of wind power which include deadband, limiting amplitude and droop coefficient is proposed. Finally, based on a certain operation mode of Yunnan Power Grid, a series of simulation using the proposed process are carried out. By constraints of required maximum of system frequency deviation and Rate of Change of Frequency (RoCoF) under various possible operation conditions, recommended values for deadband, limiting amplitude and droop coefficient are given.","PeriodicalId":403879,"journal":{"name":"2020 IEEE Sustainable Power and Energy Conference (iSPEC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133192552","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}

Conventional static excitation system uses Supplementary Excitation Damping Control (SEDC) to suppress SSO, but the response time is limited by the excitation winding time constant. Besides SEDC, flexible excitation system can provide an extra damping channel controlled by Subsynchronous Damping Controller (SSDC). This paper proposes a novel SSDC and its corresponding control method for flexible excitation system. Then the effect of SSDC is analyzed by complex torque coefficient method.
