Scale Analysis of Pumped Storage Power Station in Henan Province Based on Power Optimization Planning
At present,the power supply for peak shaving in Henan power grid accounts for a small proportion,which mainly depends on the deep regulation of thermal power units to meet the demand for peak shaving,affecting the safe and economic operation of the power grid.Pumped storage power stations are economically feasible peak shaving power sources,with a double peak shaving effect of peak shaving and valley filling.This article adopted the power optimization expansion planning model to optimize and compare different power supply schemes in the planning year,and analyzed the installed capacity of pumped storage power stations that met the electricity demand and peak shaving needs of the power grid.The results indicate that the construction of pumped storage power stations can effectively reduce the depth of peak shaving for thermal power units,reduce system coal consumption,and ensure the safe and economic operation of the power grid.
