Research on Wind-PV-Thermal-Storage Co-generation Strategy Considering Weather Factors

The reservoir capacity of a pumped-storage power station is a key factor that restricts the regulation capacity of pumped storage,which is affected by weather factors in different seasons.In the previous studies of pumped-storage power station models,the influence of weather factors is rarely considered,which will lead to deviations in the modeling and simulation of the operating state of power system with pumped-storage power stations.The influence of weather factors on the water volume of pumped-storage reservoir is analyzed in detail,and a model of pumped-storage power station considering weather factors is established to analyze the optimal operation of wind-PV-thermal-storage power system.The results show that the variation of energy regulation capacity of pumped storage under different weather conditions will significantly affect the peak regulation capacity of the power system and the level of new energy absorption.The proposed model can more accurately and effectively simulate the influence of weather conditions on power system regulation.
