Therefore, with the goal of minimizing load shedding and maximizing new energy consumption in zero-carbon power systems, this study proposes a probabilistic economic and adequacy evaluation method. First, the paper modeled coal-fired power plants with carbon capture, utilization and storage (CCUS) equipment, concentrating solar power (CSP) plants with thermal energy storage (TES) systems, wind power plants, photovoltaic power plants and battery energy storage systems (BESS) in the zero-carbon power system. In the coal-fired power plants with CCUS equipment, the constraints of electric power output and zero carbon emissions were considered; considering the time-series state of charge constraint, a model of the battery energy storage system was established; considering the SOC of the thermal energy storage system and power balance constraints, a CSP plant model was established. The sequential Monte Carlo simulation method is used to build the process framework of probabilistic economic and adequacy evaluation. The uncertainty of new energy sources and load, and the stochastic outage of components are all considered in the framework. The effectiveness of the probabilistic economic and adequacy evaluation method for the zero-carbon power system was verified by the in-depth analysis of the modified IEEE RTS79.","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":"123918114","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}

Nonlinear droop control has unique advantage in the current sharing accuracy and bus voltage stability. As we know, during the operation of the DC system, the bus voltage should be stable, and the output of each power port should be reasonably distributed. However, the traditional droop control can increase the droop gains to improve the accuracy of current sharing, but at the same time, it will lead to a large bus voltage drop, which cannot meet the requirements of system in the current sharing and bus voltage adjustment rate. In this paper, related research is carried out to solve the system requirements of the above problems. First, this paper focuses on the mathematical control models of the linear. Next, analyses the advantages of nonlinear droop control. Then, this paper discusses the bus voltage drop in the load side and current sharing in the DC system. Final, this paper evaluates the line and converter loss in the efficiency of DC system and compares the different control strategies in the Matlab.","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":"125866332","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}

Combining image processing and photogrammetry technology, a new transmission line sag measurement method is proposed in this research. The unmanned aerial vehicle (UAV)-based data acquisition system was used to take multiple on-site images from the same transmission line at different shooting positions and angles. The image segmentation algorithm combining smoothing filtering, edge detection and boundary tracking was used to identify the sag feature points in the images. The stereo image pair forward intersection algorithm was used to derive the actual coordinate value of the corresponding sag point. Then, the accurate measurement of the transmission line sag and the distance to the ground was achieved. Compared with the actual measurement results of the on-site laser rangefinder, the average error of the new measurement method was less than 1.3%, and the maximum error was less than 2.8%, indicating that the proposed method was correct and effective and could meet the needs of practical applications.","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":"129724518","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}

Second, and improve the scientificity and objectivity of evaluation, the proposed model adopts entropy methods to evaluate its objective attributes.
