[0002] The grid's multi-energy complementary system is an important approach to optimizing energy allocation by integrating conventional power sources with renewable energy generation resources and combining them with energy storage technology. This system, centered around the concept of "wind, solar, hydro, thermal, and energy storage integration," leverages the regulatory role of energy storage equipment in both the transformation of existing power sources and the construction of new ones. Energy storage cabinets, as key equipment, fulfill the crucial role of energy storage and allocation.
