Research on Key Technologies of Distributed Energy Storage System

The distributed energy storage system studied in this paper mainly integrates energy storage inverters, lithium iron phosphate batteries, and energy management systems into cabinets to achieve energy storage and release. When a single energy storage system cannot meet user needs, the expansion of the energy storage system can be achieved through the distributed and orderly parallel arrangement of the energy storage system, thereby improving the practicality and flexibility of the system. Accurately smoothing the power fluctuations of new energy systems such as distributed photovoltaic and wind power through the distributed arrangement of energy storage systems. In addition, the joint control of distributed energy storage can achieve peak shaving and valley filling of the power grid, improving the utilization rate of the power grid.
