Furthermore, the electricity consumption behavior of different types of users are diverse. The load characteristics may change, such as peak load transferring, peak and valley differently increasing, and even peak on peak load at the same time. The intelligent power utilization can make scientific and rational use of electrical equipment, so that the electricity consumption can be reduced, which also brings a challenge to load forecasting. Based on the research of intelligent power utilization, this article employed a probability distribution model to fit the users' behavior, and established corresponding load models to characterize its interaction with the power grid. After that, based on the prospect-gray theory, a medium long term load forecasting method considering intelligent power utilization was proposed and analyzed by examples. Finally, this paper used MATLAB to get the power load forecasting result and analyze the influence of intelligent power utilization on the total power load.","PeriodicalId":142885,"journal":{"name":"2018 China International Conference on Electricity Distribution (CICED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125432353","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}

The characteristics of XLPE materials under DC electric field are studied, and a comprehensive evaluation system of DC XLPE cable insulation is proposed. Results shows that the conductivity of DC XLPE insulation is more sensitive to the change of operating temperature and field strength. With the increase of temperature, the breakdown strength of XLPE is gradually reduced. Because of the existence of space charge in the DC electric field, there is an obvious electric field distortion in the XLPE insulation. The higher the temperature, the greater the distortion of the electric field, and the modification can be very slow through the nano modification.","PeriodicalId":142885,"journal":{"name":"2018 China International Conference on Electricity Distribution (CICED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114064247","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}
