[0002] In the development of society, clean energy has been widely used, among which the development of wind power and photovoltaic power generation is particularly rapid, but the power generation capacity of wind power plants and photovoltaic power plants fluctuates greatly with changes in external conditions. It is necessary to evaluate and analyze the output capacity of its power generation; on this basis, further link with thermal power to ensure the stability when connected to the grid; the combined output capacity of the existing wind-solar combined power generation system mainly depends on dispatching Personnel estimation, which often has the disadvantages of long estimation time, low efficiency, and poor accuracy. In order to ensure the accurate, reliable, and efficient estimation of the combined output of wind and wind in the regional power grid, improve the efficiency of new energy use, and reduce carbon dioxide emissions, it is necessary to provide a a new method of analysis
