Abstract

As the scale of offshore wind farms continues to expand and the offshore distance becomes farther, traditional centralized offshore substations are faced with the problems such as large installation capacity and construction difficulties. To solve the above problems, the offshore light substation is introduced, and a game optimization method for offshore wind farm electrical system based on offshore light substation is proposed. A life-cycle cost model of electrical system based on offshore light substation is established, an improved k-medoids clustering method applicable to the siting of light substations is proposed, the electrical system with different voltage levels is optimized, and multi-party game evaluation of the planning scheme is carried out based on combined weight method and mixed strategy. Taking an offshore wind farm in Jiangsu province as an example, the analysis results show that the game optimization scheme based on offshore light substation can effectively improve the comprehensive performance of offshore wind farm electrical system.
