Finally, in order to improve the application range of the AB coefficient method, the fitting AB coefficient method is further proposed to greatly improve the calculation accuracy of the AC short-circuit current affected by VSC-HVDC, and the correctness and applicability of the method are verified through case studies.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125393912","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}

Bilateral transaction is one of the main trading modes of green certificate, which helps to promote the consumption of renewable energy. Considering the diversity of transaction parties, this paper uses alliance game to study the cooperative multi-person bargaining strategies of green certificate bilateral transaction. Firstly, this paper proposes two kinds of green certificate bilateral transaction alliance mechanisms, which are \"one-to-many\" and \"many-to-many\". Secondly, this paper studies the multi-person bargaining strategies of green certificate bilateral transaction, and discusses the benefit distribution of alliance transaction. Finally, the paper analyzes the bargaining results of the two alliance mechanisms and verifies the rationality and fairness of the benefit distribution, which provides the basis and support for the bargaining strategy of green certificate bilateral transaction multi-player alliance. The results show that: The multi-person bargaining strategies of green certificate bilateral transaction are reasonable and fair based on the contribution of alliance members and considering the bargaining power of transaction subject, credit risk of transaction subject, and stability of renewable energy output, so as to ensure the stability of the alliance and the smooth progress of green certificate bilateral transaction.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126153805","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}

Therefore, we design a check protocol on regional power grid considering operation of the provincial power markets. At first, the initial market-clearing in each province is carried out based on the initial schedule of the tie-lines, and the market-clearing results are reported to the regional dispatch. Secondly, the overall regional security check is carried out to obtain accurate overrun results, and then correlation between violated security constraints and units are established through equal and opposite adjustment in pairs. Finally, the regional overrun security constraint set is distributed to the corresponding provinces, based on which each of provinces conduct re-clearing by taking regional key security constraints into account, and coordinated to the regional power grid so as to meet the security constraints. The proposed method is verified by a power grid examples.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125899522","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}

As a result, different grid codes have been proposed to confine both the steady-state and dynamic behaviors of PV power stations. Some of these requirements can be easily met, while some need special design for the control strategy. PV power stations can control their ramp rates of output power and provide frequency support as well as virtual inertia to the power system by properly utilizing the Limited Power Point Tracking (LPPT) control. However, the frequency regulation and virtual inertia control fulfilled by LPPT requires PV power stations to operate at derating mode, resulting in large amount of solar energy curtailment. Thus, the installation of battery energy storage system (BESS) is extensively used for providing virtual inertia support. This paper proposed a coordinated dynamic control scheme for a PV power station equipped with the BESS system, aiming to provide frequency support and virtual inertia to the power system during disturbance. The simulation test and theoretical analysis for the impact of the developed coordinated dynamic control strategy on the power system are carried out in several case studies.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129361477","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}
