Dynamic calculation method for SOC (State of Charge) of battery of energy storage power station

The invention discloses an energy storage power station battery SOC dynamic calculation method. The method comprises the following steps that S1, a first external feature sequence of a single battery in a charging working condition mode and a second external feature sequence of the single battery in a discharging working condition mode on a segmented time domain are sequentially obtained; s2, acquiring a first internal characteristic sequence corresponding to the first external characteristic sequence and a second internal characteristic sequence corresponding to the second external characteristic sequence based on a parameter identification strategy; s3, acquiring a first adjustment parameter sequence and a second adjustment parameter sequence; s4, performing synchronous correction on segmented time domains of the first external feature sequence, the second external feature sequence and the first adjustment parameter sequence; s5, obtaining an SOC sequence of the single battery through an ampere-hour integra
