Research on Optimal Scheduling of Wind/Light/Pumped Storage Combined Operation System Based on Spotted Hyena Optimizer Algorithm

In view of the impact of distributed energy generation on the distribution network,this paper puts forward a solution to optimize the operation of the joint operation of pumped storage power station and new energy power generation.Considering the constraints of power balance,start-up and shutdown of pumped storage units and condition conversion,a multi-objective optimal scheduling model including wind power,solar energy and pumped storage power stations is constructed,and the solution is carried out by using the spotted hyena optimizer algorithm.The simulation results show that after adding the pumped storage power station to the grid connected system of the wind and solar system,it can cut the peak and fill the valley of the power system,with significant economic benefits.The spotted hyena optimizer algorithm has obvious advantages in convergence speed and global optimization ability.
