DYNAMIC STABILITY EN HANCEMENT OF WIND EN ERGY CONVERSION SYSTEM USING ADAPTIV E CONTROL STRATEGY

Modern wind power applications require efficient and flexible control strategy that adapt themselves to the changes in load and other disturbance . The interaction of grid and its impact on wind turbines have been in focus over the years . The wind turbines, among the various distributed generation system are considered to be potential sources of power quality issues due to the dynamic changes in the wind turbine operations. Thi s paper presents an adaptive PI control strategy to stabilize the dynamics of Wind Energy conversion system (WECS) and to improve the g rid voltage profile during post fault conditions. The dynamic performance of wind system is improved by a self - tuned control strategy at the transmission side. A new technology for tracking a re ada pted to extract the maximum power from the available wind b y considering the uncertainties occurring in wind speed.
