Abstract：The cascaded hydro-photovoltaic-pumped storage hybrid power generation system, combining cascaded small hydropower, photovoltaic and pumped storage, is one of the most important means of multi-energy complementarity in the future. In this paper, the recent advances of renewable energy hybrid power generation system in recent years was summarized, and the complementary operation mode of cascaded hydro-photovoltaic-pumped storage was analyzed. Then, the scientific issues and key technologies were analyzed from three aspects: medium and long-term electricity complementary, short-term dispatching plan complementary and real-time control complementary. On this basis, the research framework was proposed from four aspects: allocation and optimization of power capacity, joint operation control and intelligent dispatching of hybrid power system, development of variable speed constant frequency pumped-storage equipment, and application demonstration, which provides valuable research ideas for the cascaded hydro-photovoltaic-pumped storage hybrid power generation system.
