Abstract: In order to solve the problem that the direct output power of wind power system has great impacts on the power quality and stability of power grid. This paper proposed a grid converter based on battery energy storage. In wind power system the grid converter could smooth the wind power fluctuations, supply the reactive power for the grid when grid faults occurred, and achieve the uninterruptible power supply for local loads under the conditions of grid-isolated operation and the rapid switching from grid-isolated to grid-connected with no impact after the grid resumed normal operation. By using MATLAB/ SIMULINK, this paper established the model of battery energy storage grid-connected system. The simulation results verify the correctness of the analysis.
Key words: battery storage; grid converter; wind power plant; voltage source converter
