Dispatching of wind farms using battery energy storage
In this paper, a STATCOM interfaced battery energy storage system (BESS) is considered for smoothing intermittent power output of a large wind farm so that it can be dispatched. 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. The paper investigates the main design issues related to BESS – the control ...
