Abstract
Hybrid wind energy storage system smoothes the randomness and fluctuation of wind power output, so wind power becomes dispatchable. To cope with the operation of hybrid wind energy storage system, this paper established a multi-time scale operation model of hybrid wind energy storage system. The aim was to maximum the expected profit of the hybrid system considering the randomness of the wind power output and the charge/discharge frequency controlling of the battery. Scenario reduction algorithm and mixed integer programming technique were developed to solve the problem, the planned power generation of the hybrid system before and in the day was supplied, in addition, the online scheduling information was also provided. The proposed model can provide power generation scheduling of the hybrid system for the operators.
