Optimal operation of wind-light-pumped storage combined power generation system

Considering the wind - light - joint pumped storage power generation system low output due to the fact that each part is of low output, and to improve particle swarm gravitation hybrid algorithm, inertia weight and chaos algorithm were introduced into the traditional particle swarm algorithm of gravity. The capability and precision of the traditional algorithm optimization were Improved. precision is not high.The improved particle swarm gravitation algorithm is applied to a practical engineering example to optimize the output of each part of the co-generation system and obtain the maximum economic benefit.The results show that the improved algorithm has the best accuracy and the shortest iteration times. After the optimization of the output of each part of the joint generation system, the largest economic benefits were achieved.
