Research on Optimal Operation of Wind Power-Pumped Storage Joint System Based on Improved Bat Algorithm

In order to effectively solve the problem of fluctuation of wind power output, the optimal operation model of wind power-pumped storage joint system considering the output fluctuation is established. With scale expansion of the joint system model, the conventional algorithm may have certain limitations. Therefore, according to the characteristics of bat algorithm with dealing with high dimension, multiple constraints, the bat algorithm can be applied to the joint optimization operation of wind power-pumped storage joint system. This paper proposes an improved bat algorithm. The results show that the joint operation of wind power-pumped storage can effectively stabilize wind power output fluctuation when the improved bat algorithm is used. The convergence speed and optimization precision is obviously improved comparing improved bat algorithm with basic bat algorithm and PSO algorithm.
