In the optimal allocation of energy storage, the refined IES mathematical model corresponds to a more reasonable and accurate energy storage capacity. An optimal assignment model of electric/heat/cooling storage which are considering the part load performance of components in IES on the user side is extracted. The purpose of this model is to minimize the annual cost of the user-side integrated energy system, including energy storage investment costs, energy procurement costs and component maintenance costs. The piecewise linearization method is used to handle the nonlinear constraints brought by the part load performance of components to the model. The results show that although the annual cost of the proposed optimization model is slightly higher than that of the traditional model, the optimal assignment results of energy storage obtained by the proposed model are more accurate and practical.","PeriodicalId":118112,"journal":{"name":"2022 7th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132875539","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, Modular Multi-level Converter (MMC) based Multi Terminal High Voltage Direct Current (MTDC) has been confirmed that can provide the possibility for the network interconnection between regional power systems and various renewable energy resources to boost supply reliability and economy. To enhance the transient stability of the power grid, a generation rescheduling scheme by optimal emergency control that considers the risk-based dynamic security constraint and reactive power constraints is proposed. The proposed strategy can avoid subsequent N-k-1 contingencies in the harsh environment by changing the generating capacity of the generator and the operation state of the MMC. The simulation results from studies on a 10-machine-39-bus power system have been demonstrated the effectiveness of the proposed control strategy.","PeriodicalId":118112,"journal":{"name":"2022 7th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132327960","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 expounds on the organizational model of rural energy cooperatives based on goal consistency, and it analyzes the resources, capabilities, and objectives of participants. The operation mode of virtual rural energy cooperatives based on the Internet, and the participant interaction rules based on the reputation index are designed. The value chain index system of rural energy cooperatives is established, which include 6 primary indexes and 17 secondary indexes. The idea of comprehensive evaluation using TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) method is put forward. The methods of giving weight and closeness calculation of TOPSIS are improved. The combined weighting method which combining the advantages of subjective weight and objective weight is proposed. The mirror image approach method is applied to solve the calculation. The calculation and analysis of the estimation index of an energy cooperative of a breeding farm can verify the effectiveness of the organization model and evaluation method.","PeriodicalId":118112,"journal":{"name":"2022 7th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130818734","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}
