Commercial and industrial energy storage is a typical application of the distributed energy storage system on the user side, and features close distance from the distributed pv power terminal and the load center, which can not only effectively improve the consumption rate of clean energy, but also effectively reduce the loss of power transmission, and help the realization of the carbon peaking and carbon neutrality goals.

The purpose of industrial and commercial energy storage is to meet the electricity demand of industrial and commercial loads, and to realize the return on investment by making use of the difference between peak and valley electricity tariffs. C&i energy storage can cooperate with pv power generation to increase the ratio of "self-consumption priority", or it can take part in a microgrid system consisting of solar, wind, diesel generator, and other

energy sources.
