The integration of wind power into the grid is now increasing at a significant pace which poses new challenges for power system operators which result to revisions of grid code requirements (GCR) in many countries. In these grid codes, fault ride through is of primary concern. The reason for this is that when large amount of wind energy is supplying the grid, they have to continuously supply power during fault to avoid large frequency deviation. There is even bigger challenge of wind power technology which to bear the same responsibilities for contribution to power system management as...
