However, the corrosion failure of transmission and transformation equipment has increasingly become a bottleneck that restricts the safe operation of power grids. If effective anti-corrosion measures are not taken in a timely manner, transmission and transformation equipment served in various complicated atmospheric environments will suffer serious corrosion damage in a relatively short period of time, which will endanger the safe utilization of transmission and transformation equipment together with the safety of grid operation. Therefore, this paper establishes a standard corrosion spectrum grading software based on image recognition technology, which is based on the DeeplabV3+ algorithm for image segmentation. Experiments have proven that the software can identify the parts that are corroding and will corrode using mobile devices so that the corrosion status of transmission and transformation equipment can be analyzed and evaluated. The utilization of the software can dramatically reduce the safety accidents and economic losses caused by neglecting corrosion, which is of great significance to the safe operation of the power grid.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"229 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124287928","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}

Therefore, it is crucial to improve the adaptability of planning schemes to establish a foundation for the economic, reliable, and safe operation of the novel power system. In view of this, this paper proposes an evaluation framework of the adaptability of power grid planning schemes with high proportion of renewable energy. Firstly, the impact of high proportion of renewable energy on power grid planning is analyzed, and an adaptability evaluation index system for power grid planning schemes is established based on five dimensions: economic adaptability, energy structure adaptability, grid structure adaptability, reliability adaptability, and environmental adaptability. Secondly, an improved AHP-CRITIC method, combined with the TOPSIS method, is proposed for power grid adaptability evaluation. This innovative approach effectively combines objective index data with subjective decision-making, enhancing the overall evaluation process for the adaptability of practical power grid planning. Finally, the effectiveness of the proposed evaluation method is validated through the analysis of 14th Five-Year Plan for Power Grid Planning in three regions of a province, the adaptability evaluation shows that reliability adaptability and grid structure adaptability have greater influence on power grid planning adaptability, but the impact of environmental adaptability is the smallest.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116631977","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 connection of high percentage of clean energy, represented by photovoltaic, to the county distribution network will bring disruptive changes to the traditional distribution network, and bring a series of serious challenges to the carrying capacity, grid-connected capacity and operation control capacity of the distribution network. In this paper, an AC/DC dedicated collection network-based grid integration method of autonomous PV inverters to county distribution networks is proposed for better grid adaptability. The proposed method is based on AC/DC collection technology and its performance is evaluated by a comparative study with the traditional PV grid-connected method. In the simulation experiments, under the same control conditions and topology, the THD of the proposed method is less than 2% which is greatly lower than the THD of the existing method, and the response speed and stability are faster. The study results show that the proposed method has better power quality, improved dynamic performance, and enhanced dc-bus voltage stability.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123596133","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}

Due to the complexity of the harmonic compensation control strategy of the grid simulator, the simulation accuracy for specific harmonics is not exact and the stability is poor. To solve this problem, a generalized second- order differentiator is constructed and used for harmonic compensation in the paper. The controller can realize the phase-frequency characteristics of lead compensation for a specific frequency range based on the differential action, and eliminate the inherent noise interference at high frequency for the differential. By connecting the harmonic compensation control loop based on the generalized second-order differentiator in parallel with the double closed-loop PI control, the amplitude-frequency characteristics of the compensator for a specific frequency range can be freely adjusted by optimizing the parameters of the generalized second-order differentiator, and the accurate simulation of fundamental waves as well as specific sub-harmonics can be realized. Finally, the effectiveness of the proposed strategy is verified by MATLAB/Simulink simulation.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116175871","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}
