Research Review of Hydropower-Wind-Photovoltaic Joint Optimal Scheduling

Flexible regulating power supply such as hydropower can effectively suppress the fluctuation caused by wind and photovoltaic power generation. Therefore, multi-energy complementation is an effective way to solve the large-scale intermittent energy power transmission. The power generation characteristics of hydropower, wind power and photovoltaic are described. The principle of multi-energy complementarity, as well as the mode and basic model of joint scheduling are introduced. The research status of multi-energy complementary joint scheduling of hydropower, wind power and photovoltaic is analyzed, and the possible research directions in the future are prospected.
