Wind Energy Generation Interfaced System with Power Quality and Grid Support

Abstract:

The integration of the wind generator into the grid connected system becomes a challenge. The major problem is to have a dynamic reactive power support along with the controlled real power support from the source. In this paper a control algorithm is proposed to maintain the unity power factor of the source supply with no reactive power support from the source. The static compensator ( STATCOM ) is connected at a point of common coupling (PCC) with a battery energy storage system (BESS).The STATCOM and energy storage is interfaced with wind generating system, supporting the real and reactive power and also maintain the stable voltage at PCC and support the grid. The effectiveness of the proposed scheme relieves the main supply source from the reactive power demand of the load and the induction generator. The reactive power compensation by STATCOM with bang-bang controller with hysteresis based technique maintains the dynamic stability of the grid and matches the operating behavior of grid system. This scheme is simulated with a MATLAB/SIMULINK in power system block set, having interface of induction generator and non-linear load at PCC and performance is evaluated.
