STATCOM with energy storage for smoothing intermittent wind farm power

In this paper, STATCOM with battery energy storage system (BESS) is proposed for smoothing intermittent power output of a large wind farm. The main advantage of the system is that it can inject both real power (by charging/discharging the BESS) and the reactive power to the system. Simulations based on an actual wind farm data indicate that indeed with the proposed control strategy the power output of the wind farm can be smoothed to facilitate 1/2 h dispatching of the wind farm. Also, the reactive power compensation provided by the STATCOM helps to smooth out the fast voltage variations at the interconnecting bus.
