Uninterrupted Working after Separating Wind Power Plant from the Grid using Energy Storage Systems

Wind power plants have a basic role in generating of electricity. One of the problems to connect the new energy sources such as wind power plant to grid is islanding from the grid of faultreasons. In This situation, mismatch between production power and required power causes to away the voltage and frequency from thedesirable amount in isolated systems. The same conditions, depletion load caused to accelerating the rotor. To these reasons generatorsmust be turned off. In this paper we present new method to appropriate controlling on converters and pitch angle on islandingconditions by adding battery on the DC link and add the load power then consider and compare the voltage, frequency, Flicker and DC link voltage on islanding conditions when using battery and withoutbattery. The simulation result shows the improved ability of control strategy.
