Industrial energy storage means that industrial enterprises store the electric energy collected from renewable energy sources (e.g. solar energy, wind energy and biomass energy) into the energy storage system, so as to prevent energy loss, conserve energy and reduce consumption. The system can arrange and organize the time of electricity consumption by various users reasonably and in a planned way based on the pace of electricity consumption by different users. This is to narrow the gap between peak load and valley load, and make power generation capacity and electricity consumption tend to be balanced, thus achieving "peak-shaving and valley-filling effect". It helps to maintain the safety and stability of industrial electricity consumption and provide more reliable power solutions and sustainable power generation equipment for industry. The system is mainly
