BMS cooperative control system and method for electrochemical energy storage power station

The invention relates to an electrochemical energy storage power station BMS cooperative control system and method, a communication network is set for the BMS of each energy storage cabin, the BMSs ofdifferent energy storage cabins are interconnected and intercommunicated, SOC sharing of the battery of each energy storage cabin is realized, and the BMS of each energy storage cabin can acquire thebattery SOC and other data of the BMS in all other cabins. The BMS of each energy storage cabin integrates the SOC of the BMS and the SOC of other cabins, whether the battery of the cabin needs to becharged and discharged or not is judged to enable the SOC of the BMS and the SOC of other cabins to be kept at the same level, and SOC balance between the cabins is beneficial to overall efficient operation of the energy storage power station. Through holographic data analysis, bidirectional interaction with the EMS and the PCS is realized, and BMS cooperative control of the whole station is realized. 本发明涉及一种电化学储能电站BMS协同控制
