In the context of energy conservation and environmental protection, new wind energy power generation has obvious random, intermittent, uncontrollable and anti-peak-shaving characteristics. The large-scale grid connection of wind power has brought grid peaking and stable and safe operation the huge pressure has caused more serious wind curtailment and power rationing, which has seriously affected the effective use of wind resources and economic benefits. Under the dispatch of the energy management system, the all-vanadium redox flow battery energy storage power station smooths the output power of wind power generation, and cooperates with the wind farm power forecast system to improve the wind farm tracking planned power generation capacity and improve the grid-connected power quality of the wind farm. Based on this, the thesis studied the external operating characteristics of the all-vanadium flow battery (VFB) energy storage system, and carried out the modeling and simulation of the energy storage system (ESS) based on the electrochemical properties of the VFB. Systematically analyse the actual operating data of the energy storage system and evaluate the impact of its overload operation on dispatch control, and fit key parameters such as state of charge (SOC), electromotive force and equivalent resistance, and obtain functional relationships.
