The multi-terminal hybrid connection also causes its transmission line fault characteristics to be different from the traditional single DC system. Aiming at the fault characteristic analysis of LCC-VSC hybrid multi-terminal DC transmission line, it is found that there are problems of current imbalance on both sides when the transmission line fails, and the LCC branch and VSC branch have different backup protection time requirements. Traditional current differential protection has the problem of long delay due to distributed capacitive current. In view of this problem, this paper proposes a protection scheme based on current integral as a fast backup protection for traveling wave protection. The paper uses integration to eliminate current oscillation and distributed capacitance current, and solves the long delay problem of traditional current differential protection. Simulation results show that the protection principle has a strong capacity to withstand transition resistance, distributed capacitance and noise interference. It can be used as backup protection for LCC-VSC system.","PeriodicalId":403879,"journal":{"name":"2020 IEEE Sustainable Power and Energy Conference (iSPEC)","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132452197","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}

Meanwhile, complex nonlinear correlations between renewable energy outputs can also influence the economic dispatch of power system and these correlations should be accurately described. Demand response, as a power balance adjustment method, has obvious effects in promoting the consumption of renewable energy and ensuring the safety and economics of power system operation, especially under power market conditions. This paper proposes a novel stochastic economic dispatch method considering demand response, and Monte Carlo method based on M-Copula theory is adopted to deal with the complex nonlinear correlation between renewable energy outputs, which can avoid the limitations of each single Copula function to great extend and achieve further accuracy of economic dispatch results. The necessity and effectiveness of proposed method can be proved by the case studies.","PeriodicalId":403879,"journal":{"name":"2020 IEEE Sustainable Power and Energy Conference (iSPEC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133134688","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}

This paper proposes a microgrid resource optimization schedule strategy based on the flexibility of distributed power generation. In the day-ahead planning stage, the day-ahead optimal scheduling model is established by combining the operating costs of the microgrid and the demand response capacity benefits; In simulation stage simulating and predicting power fluctuations and the real-time demand of the upper grid, then through the neural network obtaining the intra-day schedule model to prepare for intra-day schedule; In the intra-day stage, the tie-line power is input into the neural network model through the demand response signal of the upper-level power grid to obtain the power of each distributed. The strategy proposed in this paper can not only guarantee the economic operation of the microgrid, but also meet the real-time scheduling requirements of the upper-level grid. Finally, the results of the calculation examples verify the economy and effectiveness of the strategy.","PeriodicalId":403879,"journal":{"name":"2020 IEEE Sustainable Power and Energy Conference (iSPEC)","volume":"267 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124343067","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 research of combining the digital achievements of power grid engineering and visualization technology of digital power grid multi-level display can effectively provide power grid visualization support and solve the actual work needs for the operation and maintenance. In this paper, a graph model based on homeomorphic transformation of the power grid topology is proposed to simplify and stratify the network structure of the grid. Subsequently, the contents and forms presented in the digital grid under three different levels of macro, meso and micro are studied from both topological and information hierarchy, respectively. Next, this paper classifies the key nodes of the power grid based on the graph theory, from which the primitive graph model is progressively simplified to form three abstraction level topological models: primitive, skeleton and geographic. The reverse application of these three topological models can gradually realize the hierarchical display of digital power grid. Finally, Jiangsu Power Grid was taken as the application object to demonstrate the prototype of multi-level display for digital power grid.","PeriodicalId":403879,"journal":{"name":"2020 IEEE Sustainable Power and Energy Conference (iSPEC)","volume":"490 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117022368","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}

However, the problem of excessive margin is easy to occur, and these methods are difficult to consider the influence of distributed generation (DG). Therefore, this paper takes reliability as a constraint, and proposes an evaluation method for the best power supply capacity of active distribution system considering the interruption cost. This paper is aimed at a two-stage medium-voltage power distribution system with a main transformer considering the access of DG, aiming to optimize the integral economy cost with the factors considering the network construction cost and the interruption cost. It built a mathematical model for evaluating the best power supply capacity, and proposed an optimization method based on the sequential Monte Carlo simulation method and genetic algorithm. Also, it finds the best power supply capacity that harmonizes the reliability and economy with actual cases and different boundary conditions such as the land occupation cost and the interruption cost. The case study illustrates that it can improve the economic efficiency of distribution networks, exploiting their supply potentiality.","PeriodicalId":403879,"journal":{"name":"2020 IEEE Sustainable Power and Energy Conference (iSPEC)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123902396","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}
