On this basis, an insulation condition assessment method is proposed. In order to solve the physics coupling model, this paper proposes a corresponding iterative solution process based on COMSOL Multiphysics. Using the above model and method, this paper analyzes the fields distribution of a bushing model and conducts an insulation evaluation. In the process of designing and maintaining the insulating part, more attention should be paid to the distribution of the electric field. Significantly increased areas and locations will be the weak link in insulation, but the temperature will still be a need-ism factor.","PeriodicalId":413409,"journal":{"name":"2022 IEEE 6th Conference on Energy Internet and Energy System Integration (EI2)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114817545","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}

Therefore, it is very important to detect the fault in the early stage of the inter-turn short circuit fault. This paper presents a method to detect the number of inter-turn short circuit fault turns of the DASR based on modified active power (Pm) and modified reactive power (Qm), at low voltage with low frequency. The formulas for Pm and Qm are obtained by adding correction factors to the formulas for active power and reactive power respectively. Their correction factors are obtained by using genetic algorithm. The variations of Pm and Qm under normal condition and short circuit condition with different turns are studied. The inter-turn short circuit fault with different frequency and different fault location is simulated. It provides a feasible method for detecting the inter-turn short circuit fault of the DASR and determining the number of short circuit turns.","PeriodicalId":413409,"journal":{"name":"2022 IEEE 6th Conference on Energy Internet and Energy System Integration (EI2)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124118224","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}

Improving the accuracy of wind speed prediction can avoid this situation and improve the economic efficiency and utilization rate of wind power generation. Therefore, this paper proposes a hybrid predictive model that combines multiple optimization algorithms. Firstly, based on the envelope entropy, the particle swarm optimization improved by NSGA-II is used to select the parameter of variational modal decomposition. Then, in order to improve the machine learning model’s structure, the sparrow search algorithm is used to determine the optimal parameters of the deep extreme learning machine. Finally, use SSA-DELM to predict each decomposed component to obtain forecasting results with higher accuracy.

With the advantage of fast response, energy storage system (ESS) can be used to improve dynamic frequency response of power system. When large frequency disturbance occurs in the power grid, ESS can participate in the fast frequency regulation of the power grid and provide support for the system frequency. For the sending-end power grid where renewable energy accounts for a relatively high proportion and a large amount of power is sent out through multiple high-voltage direct current (HVDC) lines, it puts forward higher requirement on frequency performance. In this paper, a comprehensive case study is performed to benchmark a number of fast frequency support control methods based on a practical test case from Xinjiang power grid under two typical disturbances. The results of the case study indicate model-free control need less capacity usage of ESS and has better adaptability to different operating scenarios.","PeriodicalId":413409,"journal":{"name":"2022 IEEE 6th Conference on Energy Internet and Energy System Integration (EI2)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126213676","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}

In addition, the difference between residential load and wind power generation is taken as the objective function for optimal power consumption. The problem of wind energy consumption is solved by prioritizing residential load according to the correlation between the load series and wind power series in each time slot.

This paper proposes a scheduling strategy for the CEV fleet in a power-transportation coupled network. By scheduling the plug-in locations, charging/discharging profiles, and the navigation paths of the CEV fleet, the model provides energy support for the damaged power network, maximizes the revenue of urgent trip service, and minimizes the energy consumption cost. The coupled power and transportation constraints are explicitly described in the model, which are formulated into a mixed-integer second-order cone program and efficiently solved by off-the-shelf solvers.
