Abstract: The lower reach of Jinsha River is endowed with hydro-wind-solar resources，and it is a clean energy base with an installed capacity of 10 million kilowatts that China will focus on in the future.Compared with the ordinary studies on million kilowatt scale in China，the multi energy complementary system of Jinsha River clean energy base is bound to be larger，more complex in structure and more refined in scheduling requirements.Therefore，the efficient utilization of resources faces a series of new problems and challenges，such as how to arrange and admit large-scale wind-solar resources，how to describe the law of intermittent space-time power generation of new energy，and how to coordinate the long，medium and short-term operation of large-scale multi energy complementary system.This paper focuses on the actual planning and operation of the hydro-wind-solar-storage system in the lower reaches of the Jinsha River，and expounds the current solutions and methods，such as the distribution characteristics of hydro-wind-solar resources and the analysis of multi-scale complementarity in time and space，the monitoring and perception of multi-source information in complex systems of clean energy bases，and the intelligent scheduling of giant power stations.The impact of admission of large-scale wind power stations and energy storage on river basin cascades and power grids is analyzed in depth.In terms of the characteristics and description of the wind and solar power generation system，admission of large-scale wind and solar energy storage，long，medium and short-term comprehensive prediction of water and solar energy，multi-dimensional and refined collaborative scheduling of reservoir groups，multi-energy complementary system and multi-temporal and spatial scale scheduling operation mode，we systematically refine the technical difficulties and solutions of the basins hydro-wind-solar-storage complementary scheduling.It is suggested to strengthen the research on technical means from four aspects：multi-dimensional fine coordinated operation of reservoir groups，long，medium and short-term comprehensive forecast of multi coupled hydro-wind-solar，adaptive regulation modeling of water resources coupling system dynamics，and multi temporal and spatial scale operation mode of basin hydro-wind-solar pumping and storage multi energy complementary system.The research results can effectively support the efficient utilization of 10 million kilowatts of clean energy in the lower reaches of Jinsha River，and help to achieve the national carbon peaking and carbon neutrality goals.
