Reasonable planning and construction of pumped-storage power stations can provide support for the safe and stable operation of large-scale access of new energy to the power system,which is conducive to the large-scale,high-proportion and high-quality development of new energy,and is of great significance to the construction of a new power system and the promotion of green and low-carbon energy transformation.The reasonable planning scale of pumped-storage power stations in each provincial power grid is a controlling index for scientific and orderly construction of pumped-storage power stations,which are the basis of project planning,preliminary design and approval.The research and determination of reasonable demand scale is the key to promote the orderly development of pumped-storage.Therefore,on the basis of a large number of planning practices,this paper summarizes and proposes a method for demonstrating the reasonable scale of pumped-storage for provincial power grids.Taking the power grid of a province in 2030 as the research object,different power supply planning schemes are formulated to establish the power system operation model combining load prediction results,power supply and power grid development planning.Taking meeting the demand of power system and achieving the lowest present value of the total cost of construction and operation as targets,it is proposed that the reasonable installed capacity of pumped-storage power station in 2030 in this province is about 20 230-21 430 MW.
