Research on optimization design method for offshore wind power cluster transmission system oriented to energy islands
Offshore wind power clusters oriented to energy islands are facing entirely new challenges in the direction of power transmission planning,such as transmission schemes and optimization strategies.In this paper,the optimization design scheme of the power transmission system for offshore wind power clusters oriented to energy islands is originally proposed,taking the offshore wind farm,energy island,and onshore connection point as the research subjects.The optimizing method for the layout of power transmission connections for offshore wind power clusters based on multi-layer facility location optimization is proposed,and the problem is mathematically formulated using mixed-integer programming.Finally,a scenario of offshore wind power cluster oriented to energy island at acertain sea areain our country was simulated,and the optimal costs of two schemes,direct connection from the offshore wind farm to the onshore connection point and the connection through the energy island proposed in this paper,were compared through simulation.The simulation results show that the scheme through the energy island can reduce the power transmission costs of the offshore wind power cluster.
