It is vital for the construction and planning of new power system to reasonably optimize the installed ratio of various power supplies. To this end, this paper proposes a capacity allocation optimization method of multi energy power system based on complementary equilibrium theory, and establishes the capacity optimization models of multi-energy system such as wind power, thermal power, nuclear power and energy storage with the objective of minimizing the operation cost of the whole network. The model adopts the load characteristics, the output characteristics of new energy and the operation characteristics of energy storage power stations in the target power grid. The annual output time series of wind/photovoltaic and the load series are used as the input of the model. Through the annual time series production simulation calculation, the optimal capacity ratio of wind-photovoltaic-thermal-nuclear-storage system is determined to meet the conditions. Finally, a regional power grid in China is demonstrated as an example to verify the effectiveness and practicability of the proposed model and method.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"20 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":"126876347","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}

However, it is critical to deliver this massive amount renewable power to the east side of China due to the imbalance of population. In addition, global energy interconnection has become increasingly popular. As an effective solution, ultra-high voltage direct current transmission systems (UHVDC) can easily achieve asynchronous grid interconnection, as well as a balanced distribution of renewable energy. This paper presents an approach to encounter overvoltage suppression by new UHVDC control strategies, as well as installing controllable lightning arrester. Validation is performed on real-time digital simulator (RTDS) by using the real data from Zhalute-Qingzhou ± 800 kV UHVDC project. The results show presented approach of overvoltage suppression can reduce the level of overvoltage from sending end by up to 15% when AC system fault happens at the receiving end.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"4 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":"116690214","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}

First, the game relationship between different investment entities of offshore wind power access projects is analyzed, and a slightly altruistic Stackelberg game model is established that considers later returns. Then, aiming at the value evaluation of investment entities under the influence of uncertain factors, considering the uncertainty of offshore wind power prices and grid transmission prices, a value evaluation model for offshore wind power and onshore power grid expansion projects based on real options is constructed. Finally, the effectiveness of the proposed method is verified by numerical example simulation.
