In order to solve the problems of reduced absorption rate and abandonment of wind and solar energy in the power sys-tem caused by the integration of wind and solar energy into the power grid,a multi-objective optimization model for wind,so-lar,thermal,and storage joint external transmission scheduling under flexible resource coordination planning is designed by searching for energy storage devices inside the power grid and combining them with distributed power sources in space.On this basis,a comprehensive analysis is conducted on the four major parts of wind power generation,solar power generation,thermal power generation,and energy storage systems,and output models for the four types of equipment are set up.This paper con-siders flexible resource coordination planning,sets objective functions,calculates the operating and environmental costs of the power grid,obtains constraints for two types of costs,and establishes a multi-objective optimization model for power grid scheduling.The experimental results show that the absorption powers of the multi-objective optimization model in four scenari-os are 567 MW,542 MW,468 MW,and 1024 MW,respectively.After optimization,the power consumption of the power grid is significantly better than before,and the abandoned wind and light power are also significantly reduced,indicating the ef-fectiveness of the power grid scheduling optimization model.
