Connecting EVs to distribution network to participate in dispatch has become an effective way to reduce the negative impact of EVs on the grid. For this reason, aiming at the uncertainty of the renewable energy considering EVs’ dual characteristics of the source and load, a data-driven two-stage robust optimization model of distribution network is built to find the economically optimal solution. The model uses norm constraints of the uncertainty probability distribution confidence set and flexibly adjusts the conservatism of the model through confidence level. The objective function of minimum cost is established, and the model is transformed into a mixed integer linear programming model and the model is iterated to obtain the optimal solution through the column-and-constraint generation algorithm. The simulation results showed that EVs can effectively reduce the distribution network daily operation cost. The operation cost in the randomly charging mode is higher than that in the orderly charging mode. In addition, the confidence level can flexibly adjust the conservatism of the model, and with the increase of confidence level, the robustness of the model is enhanced.","PeriodicalId":411512,"journal":{"name":"2021 3rd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129363021","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 concern of global warming and environmental impact reinforces shifting from traditional power resources such as fossil fuel to renewable resources such as photovoltaic (PV) sources. The stochastic nature of PV power directly affects the stability of the grid. Therefore, PV power forecasting allows power stations to know before hand how much PV power will be available, which assists in ensuring that the grid remains in stabilized condition. Here, PV power from India is analyzed and predicted using machine learning methods. The main goal of this paper is to analyze power patterns and predict the future 15 minutes of PV power using random forest regression. The analysis shows that irradiance and ambient temperature have the highest correlation with the DC power. It also shows patterns of similarities between power consumption profiles on different days of the week.","PeriodicalId":411512,"journal":{"name":"2021 3rd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129040975","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}

With the rapidly increase of the electric consumption and load capacity of the transformer, high hot-spot temperature has become one of the essential issues concerned by engineering manufacturers. The driven force of oil flow is thermal buoyancy in transformer for Oil Natural /Air Forced (ONAF) cooling mode, besides, the internal oil flow paths are complex. Therefore, the heat dissipation for ONAF transformers becomes a key index determining the loading power, and it is of great theoretical and practical significance to study the oil flow distribution and temperature field. In this paper, the finite volume method is used to simulate the temperature and flow fields of a 110 kV ONAF transformer. The results show that the temperature inside transformer increases gradually with the height, and the hot-spot is found located below the low-voltage winding top. The velocity of oil in the vertical oil channels are greater than the horizontal oil channels between the coil discs. It is found that introducing washers in the transformer design can enhance the flow rate of horizontal oil channels and strengthening the heat dissipation of windings. The research results can be used to guide the evaluation of load capacity and the heat dissipation structure design of the transformer.","PeriodicalId":411512,"journal":{"name":"2021 3rd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"492 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116694295","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 multiphase interleaving topology can inhibit the ripple of input current and output voltage, and its fault-tolerant operation control method meets the deep sea low maintenance level design needs. Based on the new topology, the phase shift modulation law and one-way power flow control scheme under multi working conditions are studied.

The vehicle registration information is used to forecast the number of electric vehicles (EVs) in the area, while the GIS data are used to represent the whereabouts of electric vehicles. The number of EVs can be representatively characterized by the size of areas and the length of roads. The area-based approach requires fewer data and less computing effort and therefore is suitable for a broad overview of estimation, especially for urban areas. While the road-based approach gives more reasonable results for countryside areas such as a land with mountains and forests.
