The wind power penetration is increasing tremendously.To integrate this huge amount of energy contribution from wind firms into our current electrical system is a big challenge for both power system planners and operators because of different behavior of wind power plants than the conventional power plants. It is required from the wind power plants that it should contribute in grid support such as frequency, voltage and reactive power control and it should behave as a conventional power plant during normal and abnormal conditions. For this reason transmission system operators (TSO) of...
