Abstract

Aiming at the problem of power station planning in areas with abundant solar energy resources and hydropower resources, considering the volatility of solar power generation and the flexibility requirements of power grid, a planning method of pumped storage power station is proposed. Firstly, considering the centralized and distributed photovoltaic power supply and solar thermal power station at the same time, the complementary mechanism of light-water-storage is analyzed, the correlation and restriction relationship between each power station is studied, and the coordinated complementary framework of light-water-storage is established. Then, considering the investment construction cost and flexibility optimization goal, a bi-level programming model of pumped storage power station is established. The C-DCGAN with adaptive data migration function is used to generate the planned power generation scenario of the optical-water-storage system, and the NSGA-Ⅱ algorithm suitable for the iterative solution of the bi-level programming model is used to solve the model. Finally, combined with the actual regional power grid and river data, the feasibility of the proposed pumping station planning method is verified. The results show that the proposed planning method can effectively suppress the fluctuation of new energy output in hydropower-rich areas and give full play to the unique advantages of the region.
