Multi-energy complementary HWSS is guided by the principle of maximizing the development of wind and solar power, relying on flexible regulating power sources such as cascade hydropower, PSH and new energy storage to optimize the combined operation of hydropower. Multi-energy complementary HWSS is guided by the principle of maximizing the development of wind and solar power, relying on flexible regulating power sources such as cascade hydropower, PSH and new energy storage to optimize the combined operation of hydropower. Multi-energy complementary systems and energy storage technologies are indispensable components in the transition to sustainable power systems. Examples of multi-energy complementary systems include solar power, wind power, hydropower, thermal power systems, and biomass power, among others. The. With PV energy as the main power supply, an integrated complementary power supply system consisting of wind, hydro, thermal and other power sources is added to provide integrated solution of multi-energy complementary with wind, solar, thermal, hydro, energy storage and pumped-storage, and strive. In the pursuit of sustainable and reliable residential energy solutions, the concept of multi - energy complementarity, especially the integration of wind and photovoltaic (PV) energy within solar home energy storage systems, has emerged as a promising approach.
