A new multi-stage coordinated power system planning method considering renewable energy access

Abstract

Abstract When renewable energy is connected to the new power system, it will affect the normal operation of some energy storage equipment, resulting in too small internal generation capacity of the new power system and insufficient capacity of the new power system. Therefore, based on the consideration of renewable energy access, a new multi-stage coordinated planning method for power system is studied. This paper analyzes the demand for peak shaving capacity of the new power system and determines the access point of renewable energy. a new multi-stage coordinated planning model of power system is built, and the method of multi-stage coordinated planning of power system is studied by solving the model. Set up the experimental environment, give the parameters of the experimental equipment, and design the comparative experiment. The results show that the coordinated planning method studied in this paper can help to reduce the operation cost of the new power system and ensure the economic benefits of the new power system.
