The present study aimed to explore the feasibility of using a small cascade hydropower station group as the only complementary power source for photovoltaic generation. . A hydro–solar hybrid system is an important solution for expanding renewable generation capacity under the percepts of the energy transition. Firstly, a multi-objective optimization scheduling model is constructed to consider. . The Zhucheng Viao energy projects in Weifang, Shandong Province, represent a groundbreaking shift in renewable energy practices. Considering the randomicity of photovoltaic output and runoff, hydropower station with good regulation capability is often used as a complementary power. . Aiming to mitigate the impact of power fluctuation caused by large-scale renewable energy integration, coupled with a high rate of wind and solar power abandonment, the multi-objective optimal dispatching of a cascade hydro–wind–solar–thermal hybrid generation system with pumped storage hydropower. . bstract. As a result, the power of hydropower plants must take a rapid adjustment esponse.
