AI Technical Summary
The power regulation capability of battery energy storage systems in DC microgrids is insufficient, and the existing dual-battery energy storage systems lack flexible regulation capability under a fixed ratio, resulting in insufficient power regulation capability under certain operating conditions.
By using a distributed energy storage system, combining the temperature coefficient of series-connected battery cells, the influence factor of battery remaining capacity, and the power distribution weight factor, the operating power of the temperature regulation subsystem is controlled to achieve a balanced power distribution among different power supply systems and optimize the state of charge and temperature balance of battery modules.
It improves the power output level and safety of series-connected battery cells in the energy storage system, maximizes the utilization of energy in the distributed energy storage system, and maintains the state of charge balance among the power supply systems.
