Distributed Wind Turbine Integrating Energy Storage System Optimal Planning Based on Trilateral Interest Subjects

The integration of distributed generation may have a great impact on the stable operation of power system. Aimed at the distributed wind turbine (WT) integrating energy storage system (ESS) planning in medium voltage distribution network, an optimal planning method considering the benefits of distribution network company, WT owner and power consumer is proposed. Besides, a scheduling strategy adopting the reactive power adjustment capacity of WT inverter and power control system of ESS is presented. The demand response is also considered in the proposed method. The planning model is solved by NSGA-II, and more practical schemes of the site and capacity of distributed WT and ESS as well as the trading price between distribution network company and WT owner can be acquired.
