The general law of the influence of the laying mode of the cable body on the fire spread trend is obtained: the smaller the cable spacing is, the later the generation time of CO and HCl is; The temperature rise of parallel cables during combustion is low, and less toxic gases such as CO and HCl are produced; When the cable is laid in fewer layers, the time of CO produced by cable combustion is earlier; The number of cable layers has little effect on the generation rate of CO2 and HCl in the early stage.","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":"133177628","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}

Since wind power often has anti-peak shaving characteristics, the peak shaving problem of wind power high-penetration power systems is particularly prominent. Quantitative calculation of the system peak shaving cost of a high proportion of wind power grids is of great significance to the establishment and improvement of the peak shaving market in the northern part of our country, the promotion of rational system development and planning flexibility, and the improvement of system flexibility. Based on the analysis of existing wind power system peak shaving cost estimation methods, this paper proposes a comprehensive cost estimation method for system peak shaving under high wind power penetration rate, considering flexible resource investment and peak shaving market, and studies different wind power systems. The changing law of system peak shaving cost under the penetration rate; and the actual power system in a certain area of my country is used to simulate the peak shaving cost under different wind power penetration, which shows the effectiveness and rationality of the 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":"124114632","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 this case, the DC voltage change will become a serious problem. Droop control brings a feasible solution dealing with this problem. In this paper, a calculation method of P-V droop coefficient based on virtual resistance is proposed to optimize the droop control coefficient and control the DC voltage stability. Firstly, the relationship between the voltage of DC nodes and the voltage of point of common coupling (PCC) is analyzed. Thereafter, the relationship between bridge arm voltage of converter station and DC node voltage is established according to virtual resistance. The calculation method of P-V droop coefficient based on virtual resistance is then derived according to the above analyses. The calculation method was then analyzed at two extreme conditions and a control dead zone was found to exist at one extreme condition. Therefore, a corresponding solution that recalculating the droop coefficient by introducing the error of active power reference is proposed to improve the control strategy. Finally, a three-terminal VSC-MVDC model is built in PSCAD/EMTDC. Simulation results show that the proposed method for P-V droop control has a better performance as compared with general control strategies.","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":"124274283","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 order to accurately evaluate and calculate the lightning performance of 1000kV UHV-AC transmission lines under different design schemes and conditions, this paper combines the discharge test data of the State Grid Corporation's UHV-AC test base for negative short-wave front operating impulse voltage under long gap (up to 10m) conditions, and proposes EGM striking distance calculation formulas and correction method for the geodesic striking distance factors applicable to 1000kV EHV large-size lines. And the simulation study of the back flashover and shielding failure performance under the typical design of 1000kV UHV-AC lines was carried out using the modified EGM and electromagnetic transient program (EMTP), respectively.

With the rapid growth of DC load and the large-scale development of DC characteristic power sources such as wind and solar storage, DC Micro grid will greatly increase and become an important part of the construction of a new power system with new energy as the main body.
