The onshore converter station's output power rapidly decreases under these conditions. Due to the coupling between the VSC-HVDC transmission line and the offshore wind farms, if no proper measures to regulate the active power are taken on the wind turbine or the VSC-HVDC transmission line, it will lead to the collapse of the whole system. While, if all wind turbine power is injected into the system according to the rated value, a surplus of energy will result in significant voltage surges, thus, it will cause serious damage to electrical equipment or a reduction in the expected life of electrical insulation. Then the whole VSC-HVDC transmission system will be turned off, and the overall stability of the electrical system may be jeopardized. An overvoltage suppression control strategy is proposed and tested on an offshore wind power system that is integrated into an ac system using VSCHVDC in this paper. To suppress overvoltage, the power regulation capacity of both the wind farms and the dc lines is used. To validate the proposed control strategy, an electromagnetic transient model is built which can simulate the dynamic performance of the wind farm integrating to ac grid through VSC-HVDC under various faults. The simulation results demonstrate that the proposed strategy can effectively suppress dc overvoltage. And it can ensure that the power of wind farms produced does not exceed the limits under various types of faults.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"147 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128797722","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 battery swapping behavior of new energy vehicles is the most important manifestation of its difference from the traditional fuel vehicle operation mode. However, there is no research on the impact of electric taxi swapping demand on the operation of power grid swapping stations. To tackle this issue, a novel approach is proposed in this paper. Specifically, we use data mining techniques to perform big data analysis of GPS data from fuel taxis operating to derive the operation patterns of existing taxis. The operation pattern is then used as the basis for the operation of electric taxis to obtain the impact of different switching demands on the operation of distribution network switching stations. This paper has an effective guiding role in the planning and operation of power exchange station construction for power companies. The method proposed in this paper has the potential to provide a reference strategy for the construction and operation of battery replacement sites for power companies, enabling them to reduce the cost of operating a replacement station while ensuring the quality of service at the station.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"95 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123362299","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}

According to the current constraint of converters, the active/reactive operating domain of the DFIG-based WTG generator (WTG) is depicted, which gives that the WTG has different support capacity with different operating points. It is meaningful to allocate the current with consideration of its operating points. For different voltage dips, the same margin and the maximum active current principle are used respectively to optimize the current allocation. A fault voltage support datasheet is formed and sent to the WTGs in advance. Once a fault occurs, WTGs can react quickly to support active and reactive current according to the datasheet. The proposed control strategy can take full advantage of the remaining capacity and maximize the active current support in slight and severe fault condition, respectively. It is validated by simulation with DIgSILENT PowerFactory. The results verify the effectiveness of the proposed control strategy.1","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114778284","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 paper, a coordination and optimal dispatching model is developed for microgrids containing VSGs in the context of low carbon and environmental protection, taking into account low carbon and environmental protection, reliability and economy. The model considers the virtual inertia and reserve capacity of each type of VSG in terms of reliability, and the operating costs of each generation unit, interruptible load compensation costs, ladder carbon trading costs and pollutant treatment costs in terms of low-carbon environmental protection and economics. Finally, the improved INSGA2-DS multi-objective optimisation genetic algorithm is used to solve the model and carry out comprehensive optimisation of the power regulation and economic dispatch of the inverter and each power source, solving the problems of long computation time and difficulty in adapting the traditional INSGA2-DS algorithm to complex optimisation models. The simulation results validate the rationality and effectiveness of the proposed model, and realise the effective dispatch of the microgrid in a low-carbon, environmentally friendly and economic manner.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114867923","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}
