Research on day-ahead optimal dispatch of wind power-photovoltaic-thermal power-pumped storage combined power generation system

Vigorous development and utilization of renewable energy will help achieve my country's dual carbon goals. This paper constructs a day-ahead optimal dispatch model for windsolar-pumped-storage joint operation system and explores the day-ahead optimal dispatch results under different typical weather conditions. The results show that the introduction of pumped storage power stations can significantly improve the economic benefits of combined system operation and the stability of thermal power output, as well as reduce system pollution control costs and reduce system CO2 emissions.
