With the gradual advancement of power system reform, the potential benefits of ice storage technology application are increasing. Traditional methods for analyzing the economics of ice storage air conditioning systems tend to calculate and analyze the economic evaluation index of the system with fixed construction and operation strategies. Under the changing market environment and air conditioning load, it is difficult to accurately reflect the application value of ice storage technology. Therefore, this paper investigates a new economic analysis method that takes into account the collaborative optimization of the operation and planning of ice storage and cooling air conditioning systems. The method proposed in this paper takes the maximization of economic efficiency as the optimization objective and constructs constraints on the system operation strategy and investment plan. Finally, we build a mixed integer linear programming model which can be efficiently solved by a commercial solver. The numerical analysis takes Chongqing region as an example and analyzes the economic value of investing in an ice storage cooling air conditioning system under the local electricity price policy and air conditioning load characteristics.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129898744","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}

It is necessary to obtain the characteristics of VFTO to guide the insulation design of GIS and the electromagnetic protection of secondary equipment. In this work, we have designed and developed a differential impedance converter by using the compensation between poles and zeros in closed loop circuit and compared its measurement performance with a following type on a 220 kV test platform. The calibration and practical tests results showed that the low cut-off frequency of differential type has been greatly expanded, which can reach 0.1mHz, and the measurement accuracy of very fast transient signal has also been greatly improved than the following type. Thus, the differential impedance converter can fully meet the measurement needs of high-frequency transient voltage, power frequency voltage, and trapped charge voltage in the VFTO waveform. It can be recommended for VFTO test measurement in extra-high voltage (EHV)and ultra-high voltage (UHV) GIS substations and provide accurate data support for insulation design and energy saving of GIS equipment.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"207 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133557185","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}

For V and I insulator strings of 500 kV line and I insulator strings of 330 kV line commonly used in high-altitude areas, the bird dropping flashover discharge test was carried out under rated operating voltage and highest operating voltage respectively, and flashover probability at different falling positions of bird droppings was obtained. The easy flashover scope of bird droppings on both sides of 3.5 m and 3.0 m of V and I insulator strings of 500 kV line and 2.0 m of I insulator strings of 330 kV line is determined. According to the structural characteristics of tangent towers and tension towers on AC line, the layout scope and measures of bird thorn and thorn plate are put forward.

Firstly, this paper analyzed the mathematical model of flexible load, and then took the minimum loss of system network as the objective function, and constructed the network reconstruction model with power flow equality constraints, node voltage constraints, branch capacity constraints and flexible load regulation range as the constraints. Aiming at the problem of distribution network fault reconstruction, an improved particle swarm optimization algorithm was proposed, which was applied to ADN fault reconstruction. Through simulation comparison, it was verified that the improved particle swarm optimization algorithm has faster convergence speed and the ability of local optimal solution was proposed. Through the example analysis of the improved IEEE33 node distribution system, the advantages of the improved particle swarm optimization algorithm in distribution network reconfiguration were verified. The results showed that the method has fast convergence speed, short optimization time and stable operation.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121714106","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}
