Based on the time-series production simulation method which takes into account the time-series variation characteristics of system load and power generation output of new energy,the time-series production simulation model of hydro-optical power system is established.The optimal water-light capacity ratio is determined comprehensively from the aspects of system structure,economy,flexibility and reliability,and the rationality of the model is verified by the water-light system of the upper reaches of the Jinsha River in the Sichuan-Tibet section.The outputs of photovoltaic power stations and hydropower stations in the upper reaches of the Jinsha River are complementary within a year and within a day.For the level year of 2030,considering the retention of hydropower during dry period,the comprehensive performance of 9.136 million kW hydropower with 4 million kW photovoltaic is better,and the new non-water renewable electricity is about 6 billion kW·h.
