Research on Calibration Algorithm of SOC Interval Based on Energy Window
Article No.: 22, Pages 1 - 6
Abstract
Aiming at the problem that the energy storage power station cannot calibrate the SOC interval based on the chargeable and dischargeable power and energy, a SOC interval calibration algorithm based on the energy window is proposed. First, the battery model is simplified by analyzing the application scenarios of energy storage power stations, and the SOC calculation method is redefined. By performing Wh integration on the charging and discharging test data, the energy integral E of the OCV curve is used as the energy window reference, and the optimal charging and discharging interval under the energy window is determined according to a certain algorithm. Finally, the energy window interval calculated based on the OCV curve is mapped to the voltage interval at a specific power to complete the SOC calibration. The SOC calibration test based on the on-site energy storage power station shows that the algorithm can determine the chargeable and dischargeable power and the chargeable and dischargeable energy at the same time based on the SOC operating range calibrated by the energy window, and can provide an accurate reference for the scheduling operation. It has certain feasibility and Effectiveness.
