Take advantage of the flexible output characteristics of hydropower generators to optimize the installation capacity and siting of distributed PV from the perspective of optimal operation of hydro-PV complementary systems. The upper level of the model is to minimize the comprehensive cost to make decisions on locating and sizing distributed generations (DG) and energy storage. The lower level, with annual operation and maintenance costs and fast voltage stability as the objectives. The economic dispatching of the ADN is realized by taking into account the output of DGs, hydro-PV complementary systems, and the charging and discharging of energy storage. Two-level PSO with a local search algorithm is used to solve this model in a simplified 51-bus distribution network in a region of Yunnan.

Under the conditions of humid air (such as fog and drizzle), when they are seriously polluted, and the external insulation configuration is insufficient, the insulators will have pollution flashover, leading to a power failure of the line. UHV transmission lines feature large energy transmission and long distance. Once pollution flashover accident occurs, it will seriously threaten the stability of the power supply system [1]. Therefore, it is of great significance to determine the design of external insulation configuration of ultra high voltage project scientifically and economically. In this paper, the climatic environment, pollution source distribution and operating experience of nearby projects along the Sichuan-Chongqing transmission line are studied and analyzed. The AC pollution level is proposed. Through the research and analysis of insulator pollution test data of transmission lines along the Sichuan-Chongqing line, the key pollution accumulation characteristics of insulators in different environmental areas along the project, namely, the pollution ratio of top and bottom surface areas, are determined. The pollution flashover tests under different pollution conditions of top and bottom surface areas were carried out, and related pollution coefficients were obtained. According to the results of artificial pollution flashover voltage test of insulators, combined with the equivalent salt deposit density characteristics in Sichuan and Chongqing, the external insulation configuration under typical pollution conditions along the Sichuan-Chongqing UHV line was recommended.","PeriodicalId":187017,"journal":{"name":"2022 4th International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"1995 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131162128","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 those issues, this paper proposes a voltage support strategy based on active and reactive currents coordinated injection. The AC voltage control loop with anti-windup and adjustable reactive current limit is complemented in the current control. Meanwhile the operating conditions are divided according to the maximum available active current reference and the optimal active current reference, which are used to adjust the limits of active and reactive currents. This strategy avoids frequent mode switching and achieves better voltage support under different voltage sag depths. Simulation results verify the effectiveness of the proposed strategy.","PeriodicalId":187017,"journal":{"name":"2022 4th International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114649340","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}

Secondly, to obtain the Pareto optimal set, multi-objective particle swarm optimization is used to solve the proposed model. Finally, a fuzzy membership function is introduced to select the best compromise solution objectively and fairly.
