Power station battery consistency evaluation and equalization method and device and power station management system

The invention relates to the technical field of energy storage, in particular to a power station battery consistency judgment and equalization method and device and an energy storage power station management system. According to the power station battery consistency evaluation and equalization method, the open circuit voltage OCV of the battery in each state is mapped according to a first-order RC equivalent circuit and a self-adaptive forgetting factor recursive least square method, and then the state of charge of the battery is obtained through the OCV-SOC relation. Obtaining a battery consistency condition according to a capacity increment curve peak value reduction degree and an internal resistance difference dispersion degree, and finally performing dynamic equalization according to a battery charge state and consistency. According to the method, the charge state of the power station under the actual operation condition can be accurately and quickly calculated, dynamic equalization is performed according
