An accurate battery RUL can provide reference for replacement and remind safety risk when battery life is nearly end. There are lots of researches on battery RUL prediction. However, until now, the accuracy problem of battery RUL prediction algorithm based on little sample is still not solved. Since a single method is hard to solve the complex problem of battery RUL prediction, this paper introduces an optimized hybrid data-driven method combined with discrete grey model (DGM) and relevance vector machine (RVM). The method takes advantages of trend forecast from DGM and non-linear regression ability of RVM. The kernel parameter of RVM in the algorithm is optimized by an artificial fish swarm algorithm (AFSA). The algorithm also provides confidence interval of the prediction results, which describe the probability distribution of prediction results. Experimental data analysis with NASA battery data set shows the impact of kernel parameter on result error and the improvement on accuracy of battery RUL prediction by the parameter optimization.","PeriodicalId":123761,"journal":{"name":"2017 2nd International Conference on Power and Renewable Energy (ICPRE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131059306","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 development of wind power, solar energy and other clean energy is the right direction of the energy supply side reform, and the characteristics of electricity production and consumption determine the central position of clean energy in the structural reform of the energy supply side. On the basis of summarizing the existing methods of evaluating the capacity of wind power (photovoltaic power station) consumption, this paper calculates the number of wind power (photovoltaic power station)consumption in the whole year by means of the balance of the whole cycle and the hourly power balance and the rational operation mode of pumped storage. The method calculates the change of the quantity of wind power (photovoltaic power station) consumption in the whole year in the case of different wind power(photovoltaic power station) installed capacity and determines the reasonable scale of wind power (photovoltaic power station) installed capacity, which can greatly improve the accuracy of wind power (photovoltaic power station) acceptance. Through the empirical test, it proves that this method has strong guiding significance for power grid planning and improves the consumption capacity of wind power (photovoltaic power station).","PeriodicalId":123761,"journal":{"name":"2017 2nd International Conference on Power and Renewable Energy (ICPRE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126945002","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 structure and composition of KYN28-12 and XGN-40.5 switchgear are introduced, and analyzed the abnormal heating type for switchgear. The abnormal heating of internal contact connector, post insulator, cable parachute skirt, puncture cabinet casing, current transformer and switchgear are researched combined with the field experience of infrared thermal imaging testing. The reason of abnormal heating are analyzed and put forward the treatment scheme by using the surface temperature judgment, relative temperature difference method and similar comparison judgment method. It is shown that the position of internal abnormal heating is different with the different types of switchgear. The surface temperature judgment and similar comparison judgment method are employed in the heating of equipment caused by current. The relative temperature difference method is used in the heating of equipment caused by voltage. It can provide a practical application basis for condition based maintenance and technical guarantee for the actual field detection.","PeriodicalId":123761,"journal":{"name":"2017 2nd International Conference on Power and Renewable Energy (ICPRE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120909298","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}
