Distributed Generation (DG) is often used to export power to the utility system. Loss of main supply can cause a severe loading mismatch between DG generation and load consumption. Consequently, the voltage and frequency of the islanded system will cross the allowable limit. Due to this fact, it is essential to control the voltage and frequency in the islanding mode of operation. In this paper, control stabilisation of an islanded system with a doubly-fed induction generator (DFIG) wind turbine has been addressed. Wind DG produces variable output and is not capable to produce enough reactive power. Hence, it is imperative to develop better control system for the islanding operation of wind system. Voltage and frequency control strategies of a doubly fed induction generator (DFIG) with energy storage for islanding operation have been developed. The investigation has been carried out through modeling of a doubly fed wind turbine and an energy storage system using SimPowerSystems tools of MATLAB. The simulations have been carried out in stand-alone operation of DFIG during various wind penetration.
