Integrated Energy Management System Based on Small-capacity Second-life Battery Energy Storage Cabinets

With the rapid development of China’s economy, the contradiction between power supply and demand has become increasingly prominent. Energy storage technology has become the key to alleviating the load pressure on the power grid and improving energy utilization efficiency. This paper proposes an integrated energy management system with a distributed energy gateway as the core and small-capacity second-life battery energy storage cabinets as the foundation. Through AC/DC control and on-grid/off-grid power systems, this system can achieve real-time control and intelligent regulation of multiple energy forms. It has functions such as peak shaving and valley filling, and demand response on the grid side, which can effectively reduce energy storage costs, enhance grid stability, and promote the diversified development of the energy storage market.
