With the rapid development of mobile energy storage technology and the access of multiple types of distributed generation to low-voltage distribution network, how to quantitatively evaluate the operation loss of distribution network and analyze the access of mobile energy storage to different forms of distribution network has important guiding significance for the planning and operation of low-voltage distribution system in the future. According to the typical topology of low-voltage AC and DC distribution systems with multiple types of distributed generation access, a comparative evaluation model of AC and DC operation economy based on the power loss of the whole link of the system is established, and an optimization model of distribution network operation strategy considering the state of energy storage charge and discharge is established with the optimization goal of operation economy.","PeriodicalId":66748,"journal":{"name":"智能电网(汉斯)","volume":"41 1","pages":"115-119"},"PeriodicalIF":0.0,"publicationDate":"2022-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73751183","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}

Firstly, the influence on the voltage of the distribution network under the short-circuit fault for the distribution network is analyzed, and the ability of energy storage to participate in voltage regulation of the grid is analyzed. Secondly, considering the actual operation mode of the energy storage system, an energy storage reactive power control strategy including plant level and local control is proposed. The plant-level control uses the constant voltage control method, and the local level adopts the reactive power-voltage coordinated control method. Reactive power output is adjusted by bus voltage changes to improve transient voltage stability. Finally, the simulation analysis of the CEPRI36V7 power grid model in the Power System Analysis Software Package (PSASP) is carried out to verify the effectiveness of the proposed energy storage control strategy.","PeriodicalId":66748,"journal":{"name":"智能电网(汉斯)","volume":"32 1","pages":"137-142"},"PeriodicalIF":0.0,"publicationDate":"2022-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87599562","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 randomness and volatility of new energy pose a greater challenge to the demand for reserve capacity of power systems. Aiming at the reserve capacity characteristics of power systems with large-scale access of wind-driven generators and energy storage, this paper studies the allocation method of reserve capacity of power system and its optimal distribution method between the generating units powered by traditional and new energy in order to maintain a certain level of economy and reliability. In terms of reserve capacity allocation, considering the forced outage rate of different type of generating units, the uncertain output power characteristics and reliability index characteristics of wind-driven generators generation, the equivalent electric quantity function method is used to calculate the reserve capacity required by the energy storage devices. On this basis, the output power of each generating unit and energy storage device is optimized using immune particle swarm optimization algorithm to achieve the optimal economy. The example simulation shows that this method can ensure the reasonable optimization of reserve power when the power system meets the reliability and economy, and then improve the overall operation efficiency of regional power grid.","PeriodicalId":66748,"journal":{"name":"智能电网(汉斯)","volume":"7 1","pages":"65-71"},"PeriodicalIF":0.0,"publicationDate":"2022-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82871611","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 plan determines the principle of power grid data security classification. Based on the basic idea of “who will be affected to what extent and to what extent when the power grid data security is damaged”, it defines three classification factors that need to be considered: the degree of impact, the scope of influence, and the objects of influence, and the power grid data is divided into five security levels. In the operation stage of power grid data security grading, this paper sorts out the experience and gives the recommended grading process. This scheme basically conforms to the status quo of power grid data classification, and lays the foundation for power grid data governance.","PeriodicalId":66748,"journal":{"name":"智能电网(汉斯)","volume":"28 1","pages":"72-76"},"PeriodicalIF":0.0,"publicationDate":"2022-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83806682","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}
