Modeling and Power Control of Energy Storage System for Wind Park Based on Vanadium Redox Flow Battery

Abstract:

With the rapid increase of the installed capacity of wind power, the output power fluctuations of wind park had a great influence on the stability of the grid. Energy storage system in the wind farm can smooth the fluctuations of wind power effectively, and improve grid ability to admit wind power. The model of energy storage system based on vanadium redox flow battery was builded according to the state of charge, voltage and current characteristics. A kind of power control strategy with low-pass filtering was designed based on the new system model. Simulation results show that this model is more closer to the actual vanadium flow battery characteristics, the control strategy based on low-pass filtering can stabilize the output fluctuations of the wind farm power.
