BMS COOPERATIVE CONTROL SYSTEM AND METHOD FOR ELECTROCHEMICAL ENERGY STORAGE POWER STATION

摘要

The present invention relates to a BMS cooperative control system and method for an electrochemical energy storage power station. A communication network is provided for a BMS of each energy storage cabin, and BMSs of different energy storage cabins are interconnected and intercommunicate, so that battery SOC sharing of each energy storage cabin is realized, and the BMS of each energy storage cabin can acquire data such as a battery SOC of BMSs in all the other cabins. The BMS of each energy storage cabin determines, by synthesizing the SOC thereof and the SOC of other cabins, whether the battery of the present cabin needs to be charged and discharged to keep the SOC thereof be at the same level as the SOC of other cabins, and the inter-cabin SOC equalization facilitates the overall efficient operation of the energy storage power station. By means of holographic data analysis, two-way interaction with an EMS and a PCS is further performed, and BMS cooperative control of the whole station is realized.
