Furthermore, this unbalanced power may lead to reserve capacity deficiency in the power system, due to the thermal-electric coupling of the combined heat and power (CHP) units in IEHS. This paper derives a tractable and accurate residential thermal demand (RTD) model, which comprehensively considers the impact of weather conditions. Then, a robust scheduling strategy is employed to tackle the uncertainties of the renewable generation outputs and RTDs, suggesting a double-stage optimization model. The first stage is to identify the unit commitment with minimum operational cost. In the second stage, the feasibility of the first stage unit commitment would be checked to minimize the summation of slack variables. Besides, the robust optimization model is converted into a mixed-integer linear program via the big-M method and solved by column and constraint generation (C & CG) algorithm. The simulation results show the effectiveness of the proposed RTD model, as well as the robust scheduling strategy for IEHS.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131060760","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 multi-source fault information used in this paper includes Real-time fault information and historical fault information. Firstly, the proposed method extracts the fault features from multi-source fault information. Secondly, the probabilities of the suspected components are obtained based on Directed Bipartite Graph and Bayesian algorithm. Thirdly, the confidence coefficient of the suspected components is obtained by data mining based on Apriori algorithm. Finally, a fault component diagnosis model is established, and the output of the diagnosis model is the certainty of the target components. The target component with the highest certainty is considered as the fault component. In order to detect the effectiveness and the feasibility of the proposed method, this paper conducts a fault diagnosis case and the diagnosis results demonstrated that the proposed fault diagnosis method can obtain good discriminant result even if the information completeness is insufficient.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131084773","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}

It can not only reuse the existing intranet service data, but also ensure data security and reduce the difficulty of development and deployment. The response time is shortened by request concurrent monitoring and advanced queue technology, which can meet the control requirements of the production environment for response time and server pressure during high concurrency. The interaction of TCP long connections between internal and external networks is realized through the sorting and assembly of data packets and the one-to-one matching of internal and external network sessions. At the same time, it also provides security control functions such as service registration and identity authentication to ensure the safety and credibility of the transmitted data.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133062586","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 installing the DC-residual current device (DC-RCD), the impact of electric shock on human body can be effectively reduced. Since the specific value of the break time of DC-RCD has not been accurately concluded in LVDC system, and the break time is closely related to the voltage levels and grounding modes of the system. In this paper, a method of determining the break time of DC-RCD considering personal safety under different voltage levels and grounding modes in LVDC system is proposed. First of all, referring to IEC standards, the main influencing factors of human ventricular fibrillation caused by DC electric shock are analyzed and summarized. Secondly, the restriction conditions of the relationship between the break time of the RCD and voltage levels in different grounding modes are proposed. Finally, combining with the restriction conditions and using polynomial fitting method to process data, the specific requirements for the break time of DC-RCD under different voltage levels and grounding modes in LVDC system is presented. And by taking the nominal voltages in GB/T 35727-2017 as examples, the requirements for the break time of DCRCD in different grounding modes and some suggestions are given.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133106551","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}
