In order to promote the development of related work in China, this paper has compared the latest released IEC standards for DC energy meters with the current national standards and type evaluation outlines in China. It also has analyzed such main differences as the applicable range, accuracy requirement and influence test items, etc. In addition, according to the current application situation of domestic DC technology, it has put forward some suggestions for the standardization of domestic DC energy meters.","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123963922","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 energy storage could provide ancillary service to system operators as it temporarily stores renewable energy to deal with the variation of renewable generation, thus promoting the consumption of renewable energy. Its effect on renewable energy accommodation is well worth being evaluated so that suitable types and sizes can be chosen to minimize the investment of energy storage equipment. Moreover, other factors such as the flexibility of thermal unit could also influence the effect of energy storage on renewable energy accommodation. This paper utilizes analysis of variance-based factorial analysis method to evaluate the effects of energy storage on renewable energy accommodation. A case study is conducted to study the effect of four factors (power capacity, energy-to-power ratio, round-trip efficiency for energy storage and minimum power output for thermal units) on the rate of renewable energy curtailment in a sending-end system of HVDC transmission. The results of analysis could provide a clear guidance to system operators for subsequent planning of energy storage devices in the HVDC sending-end system.","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117328331","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 established model not only considers the profit maximization of market participants, but also considers that the system needs to maximize social welfare to clear the market. The KKT condition is used to transform the outer optimization model into the constraint condition of the inner optimization model and then the solution is carried out. The validity of the model is proved by an example. The analysis shows that the electricity retailer can design a reasonable auxiliary service package to attract users to participate in the auxiliary service, and gain profits by having resources to participate in the auxiliary service market during the high load period. At the same time, it can avoid buying electricity in the wholesale market with high electricity price, so as to bring higher profits.","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124194604","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}

Among these problems, the insulator flashover fault is the most frequent problem. Hence, in order to investigate the characteristics of surface flashover of GIS insulator attached with metal particle, an experimental platform of power frequency voltage superimposed lightning impulse was set up and the waveform of positive lightning superimposed on the negative peak of power frequency voltage was generated. At the same time, an electric field simulation model of sample was set up. It was found that when the amplitude of power frequency component was less than 30kV, the surface flashover voltage of insulator attached with metal particle under the superimposed waveform showed obvious plateau phenomenon, when the flashover voltage was almost the same as that under lightning impulse alone. However, when the amplitude of power frequency increased to 40kV, the surface flashover voltage suddenly dropped by 10% around. By comparing with elecrtric field distribution of the sample, it was speculated that the above phenomena were directly related to the partial discharge near the insulator surface caused by distorted electric field for the attachment of metal particle.","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124227850","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}
