Game optimization of Environmental Friendly New Offshore Wind Farm Power Collection System

Abstract

The electrical system of offshore wind farm is the key to deliver power to the onshore power grid. With the expansion of the scale of offshore wind farm, the traditional centralized offshore substation is facing the problems of large installation capacity and difficult construction. Therefore, a new technology-lightweight offshore substation, is introduced, and an improved k-medoids clustering method is proposed to establish the life cycle cost model of the new offshore wind farm collection system. In addition, considering the environmental impact, the collection system is optimized for different voltage levels, The Nash equilibrium theory of multiparty game evaluation is used to evaluate each scheme. Taking an offshore wind farm in a certain sea area as an example, the final results show that the integrated performance of the offshore wind farm collection system can be effectively improved by introducing the light substation and optimizing the voltage level.
