When the doubly-fed induction generator(DFIG) is connected to weak grid by series compensation or connected to the multi-infeed DC system, there is a risk of SSO of wind turbines. Therefore, it is urgent to reveal the internal mechanism and propose mitigation strategies. Firstly, this paper introduces the equivalence modeling methods of the DFIG-based wind farm, including controlled source aggregation equivalence method, equivalent parameter equivalence method, single impedance equivalence method considering the collector system, and multi-machine equivalence method. Then, the main research methods of SSO in DFIG-based wind farm connected to complex system are discussed, including eigenvalue analysis method, impedance analysis method, frequency scan method, complex torque coefficient method, and time-domain simulation method. On this basis, the mitigation measures of SSO are summarized, which are divided into power-side mitigation method and grid-side mitigation method. Finally, the future research direction of SSO in DFIG-based wind farm connected to complex system is prospected to provide useful references for the long-distance safe and stable transmission of large-scale DFIG-based wind farms.","PeriodicalId":201727,"journal":{"name":"2022 Asia Power and Electrical Technology Conference (APET)","volume":"9 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":"114969113","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 takes typhoon disasters as an example to establish the optimal planning model of energy storage system (ESS). The proposed model is a scenario-based two-stage stochastic MILP model. Fully considering the uncertainty of failure scenarios under typhoon and load, the first stage is to select the location and capacity of ESS with line hardening strategy under a limited budget; in the second stage, the charging and discharging strategy of ESS is optimized with distribution system operation strategies to minimize system losses and investment costs. The model is tested on a modified IEEE33 system.

By analyzing the volume fraction of different fault characteristic gases, it can effectively judge the fault condition and fault type of transformer, while predicting the content of dissolved gas in transformer oil can make timely warning before further deterioration of the fault to avoid the occurrence of insulation breakdown. Therefore, a prediction model of dissolved gas concentration in transformer oil based on the firefly optimized support vector machine is proposed. In order to overcome the difficulty in parameter selection of traditional random forest model, the firefly algorithm is used to adjust the parameters in RF. The test results show that FA can effectively improve the prediction accuracy of RF, and the FA-RF model has higher prediction accuracy than existing prediction methods, which can better predict the change of gas volume fraction in oil and prevent serious faults.","PeriodicalId":201727,"journal":{"name":"2022 Asia Power and Electrical Technology Conference (APET)","volume":"5 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":"133033544","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}

To address this problem, this paper first introduces a model for the operation of networked multi-energy microgrids. Then a cooperative revenue allocation mechanism based on the asymmetric Nash bargaining method, with net power output as the contribution measure to guarantee the stability of cooperative alliances is proposed. Finally, a numerical test on a 3 multi-energy microgrid systems is conducted to validate the proposed method. The results show that the proposed cooperative revenue allocation mechanism can not only effectively reflect the differences in the contribution degree of each entity within the coalition, but also avoid the problem of overly aggressive allocation compared with the Shapley value-based allocation mechanism.","PeriodicalId":201727,"journal":{"name":"2022 Asia Power and Electrical Technology Conference (APET)","volume":"8 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":"133066894","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}
