Co-ordinated frequency control of power system with high wind power penetration

The inherent characteristics of randomness and uncertainty of wind energy would have a drastic effect on power system frequency along with the development of wind power. In order to share the burden with the frequency-regulating power plants, and to improve the power system stability, it is essential for wind farm to control the frequency. Therefore, the influences of different governor control system models have been investigated with different operating modes of synchronous generators (SGs), when a total capacity of SGs is considered as 100 MVA, to control frequency fluctuation. It is seen that output frequency fluctuation can also be maintained in the acceptable range by using several number of wind generators connecting in parallel instead of using a comparatively smaller capacity single wind generator. Real wind speed data have been considered for this study. PSCAD/EMTDC software is used for simulation analysis.
