Description

technical field [0001] The invention relates to the technical field of power system operation and control, in particular to a calculation method and system for generating benefits of a pumped storage power station. Background technique [0002] The power generation benefit refers to the summary of the power generation and pumping power benefits, economic benefits and peak shaving benefits in the power grid operation system. In order to ensure the safe and stable operation of the power system in the next year, usually the power grid dispatching department will formulate the operation mode of the power grid at the end of each year. Among them, forecasting the power generation of various types of power sources is an important part. Pumped storage power plants are the most important resource for peak regulation and frequency regulation in the power grid. Scientifically predicting the power generation of pumped storage power plants in the next year will help to formulate power s...
