Recent grid codes demand the injection of reactive current during voltage dips to enhance Low Voltage Ride Through (LVRT) capability of wind turbines. In this paper, a hybrid energy storage system is recommended, comprising a supercapacitor along with a battery to achieve an efficient and smooth power output from an intermittent wind source. In the proposed scheme, supercapacitor provides an immediate reactive power support at the time of rapid load variations. BESS stabilises the output power to the grid at the time of long duration voltage fluctuations. An overall power management strategy is designed to coordinate a smooth power flow between and for the varying source and load conditions. The simulation results presented and analysed are performed using Matlab/Simulink.
