Firstly, the N-1 fault probability of power grid was calculated based on state enumeration, and the fault risk degree was defined as the indicator to describe the fault severity. The cost related to system operation, load cutting and energy storage is used as the objective function of the optimization model. According to the Lagrange multiplier, the analytical expression of the sensitivity of the objective function to the energy storage optimization constraint variables is obtained, which can be used to quantify the control ability of the capacity constraint to the energy storage optimization model. The simulation results show that the proposed optimization model of energy storage power station can improve the reliability of energy storage grid-connected system, and the sensitivity results can be used to analyze the influence of variable constraints on the optimization results of the objective function.","PeriodicalId":127339,"journal":{"name":"2023 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131184500","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 proposed a self-healing power supply method based on topology reconfiguration for the active distribution system with photovoltaic (PV) generation penetration. The aim for this self-healing method is to realize the power system self-healing and improve the network reliability. A multi-objective optimization model is established to maximize power supply restoration and minimize the number of switch actions. The genetic algorithm (GA) is used to solve the optimization problem and the graph theory is used to optimize each new solution to improve the efficiency of finding the optimal solution. An IEEE 33-node test network is used to verify the efficiency of the proposed self-healing power supply method through the single-node fault and multi-node fault scenarios. The numerical results confirm that the proposed method can improve network reliability.","PeriodicalId":127339,"journal":{"name":"2023 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132252629","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}

Firstly, the space charge measuring platform was established with pulsed electro-acoustic (PEA) method. Then, five kinds of oil-immersed paper were made as sample, of which the oil are KI50X, KI45X, S4, HI50X and S4-KI50X mixed (1:1), respectively. Finally, the space charge measurement was performed to investigate the influence of oil on the space charge characteristics in oil-immersed paper under polarity reversal. Results indicate that all kinds of oil-immersed papers share the similar polarization process, with space charge accumulation of the same polarity. However, the electric field of different transformer oil-immersed papers appear large difference, where sample of KI50X gets the least accumulation of opposite polarity charge after polarity reversal, while samples of HI50X and KI45X get the most. In the polarity reversal, different degrees of electric field distortion inside the oil-immersed papers are computed, by order from max to min are KI45X > HI50X > S4 > S4-KI50X mixed > KI50X.","PeriodicalId":127339,"journal":{"name":"2023 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"205 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114649761","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, they have great potential in terahertz nondestructive testing and are widely used in insulation equipment detection, aerospace, biomedical fields. To address the current problems of single absorption band and non-tunable, a new three-band tunable metamaterial absorber/reflector is designed in this paper. The device consists of elliptical vanadium dioxide and a metal base plane separated by a silica dielectric layer. Numerical simulation results show that when VO2 is in the insulated state, it is almost in the fully reflective state. When the vanadium dioxide is in the metallic state, there are three perfect absorption peaks in the range of 2.5 to 5 THz. The equivalent impedance and surface current distribution of the absorber are further analyzed and discussed, and the mechanism of vanadium dioxide regulation of the absorption performance is elaborated. In addition, the effect of structural parameters on the absorption effect is discussed in this paper, which provides guidance for the optimization of the structure.","PeriodicalId":127339,"journal":{"name":"2023 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130029312","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}
