Abstract:

Objectives Renewable energy generation primarily using wind, solar, and hydro power is one of the practical approaches to achieving the dual carbon goals. Therefore, it is essential to review the research on the increasingly mature and gradually systematized wind-solar-hydro complementary power generation systems. Methods Firstly, the research background and working principle of the wind-solar-hydro complementary power generation systems are outlined. Subsequently, the research progress on the systems is reviewed, including wind-solar-hydro multi-energy power prediction, configuration ratio evaluation, integrated scheduling studies, and research on wind-solar-hydro complementarity combined with energy storage technologies. Results Wind-solar-hydro forecasting faces temporal scale synchronization challenges, with short-term accuracy inferior to hydropower forecasting. The comparison optimization method and the direct optimization method are mainly used to evaluate the capacity ratio. Integrated scheduling predominantly utilizes uncertainty modeling approaches, with intelligent optimization algorithms demonstrating superiority over conventional algorithms in solving nonlinear problems. Hybrid configurations of pumped storage and emerging energy storage technologies exhibit the most promising development prospects. Conclusions In the future, breakthroughs are required in four key areas: enhancing multi-scale coordinated forecasting accuracy, strengthening flexible regulation capabilities of hydropower and energy storage, constructing intelligent scheduling platforms, and optimizing modeling and solution algorithms, thereby supporting China’s 14th Five-Year Plan for clean energy system construction.
