Power Quality Enhancement of Wind Energy by Custom Power Devices

As per the huge wind power potential, large wind energy development in rural area of North Maharashtra has played a very important role. Due to increase of wind power penetration to grid, the Power Quality issues are affected and there are certain technical limitations in the form of grid codes for wind power penetrations to grid system. Poor Power Quality acts as obstacle for effective implementations of the Indian wind grid codes, in identified case study of the Khaprale wind farm. In view of this the special case study with detailed Power Quality analysis of a Wind Farm project at Khaprale District Nashik (50 MW) is done. Similarly the various Wind Farms sites are visited and its Power Quality analysis is done. Case study of the Khaprale wind farm was analyzed by MATLAB simulations and experimental method for Power Quality point of view. The various Power Quality issues such as Voltage sag, voltage swell, Harmonics, FRT or LVRT are considered and Custom Power Device based DSTATCOM with smart energy storage system are developed according to existing nature of Power Quality under normal and abnormal conditions.
