This paper proposes a novel day-ahead optimal dispatch model for ADN based on the conditional value at risk (CVaR) to promote solar power accommodation. Firstly, the uncertainties of PV output and load are modeled by the generated typical scenarios based on historic data and K-means clustering and can be embedded in the discretized and linearized CVaR model. Then, the optimal dispatch model aimed to maximize solar power accommodation is established. Active management (AM) includes the on-load tap changer, capacitor bank, battery energy storage, and load curtailment. Constraints mainly involve power flow, nodal voltage, branch power load, and the limits of AM. The problem is finally transferred into a mixed-integer second-order cone programming one, which can be solved by the commercial solver Gurobi directly based on the branch-and-bound method. Case studies based on a modified IEEE 33-bus system illustrate the feasibility and validity of the proposed method.","PeriodicalId":221387,"journal":{"name":"2021 China International Conference on Electricity Distribution (CICED)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115001450","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}

Zinc and aluminum are both frequently-used metal material in GIS as construction and coating. Since the presence of water and oxygen, which is hard to avoid during manufacture and operation, the metal may be oxidized. Meanwhile, Aluminum oxide has been widely used as insulation materials, of which the stability when exposed in C4F7N is very important for the long-term stable operation of electrical equipment. Therefore, the compatibility between insulation gas C4F7N with alumina and zinc oxide need to be carefully verified for the engineering application of the novel gas. In this article, the compatibility was studied by both thermal compatibility experiments and density functional theory calculation. The thermal ageing test were performed, and the scanning electron microscope (SEM) and X-ray photoelectron spectroscopy (XPS) analysis were used on the solid powders. In the meantime, the adsorption energy, total charge transfer, density of states and electron density difference of the gas molecular on solid surface were calculated to evaluate their interactions. The results demonstrate that C4F7N shows certain compatibility with the two metal oxide.","PeriodicalId":221387,"journal":{"name":"2021 China International Conference on Electricity Distribution (CICED)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130344024","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}

By using the ASTM D2132-62T test method, the resistance of epoxy micron composites was evaluated by recording the time of electrical mark failure. The hydrophobicity of the sample was studied by static contact angle measurement, and the electrical and mechanical properties of the sample were tested. The results show that with the increase of the doping content of micron silica particles, the resistance to electrical marks and hydrophobicity of the samples become better, The dielectric constant of the sample decreases first and then increases, the dielectric loss is constant, the volume resistance decreases first and then increases, but the dielectric strength increases first and then decreases, and the difference of electrical properties of different samples is small. both the bending strength and the tensile strength are slightly increased, and the impact strength decreases first and then increases. the comprehensive test of the electrical and mechanical properties of the specimen increases the bending strength and tensile strength of the specimen, appropriately reduces the dielectric constant and volume resistivity, and increases the dielectric strength, which can make the resistance of epoxy micron composites better.","PeriodicalId":221387,"journal":{"name":"2021 China International Conference on Electricity Distribution (CICED)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130313675","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}
