DFIG-Based Wind Farms and Their Performance with Thermal Connected Grid

Abstract

The increasing wide spread use of wind generation on the power networks imposes the requirement that the wind farms should be able to contribute to the network support and operation as do conventional thermal generation stations based on synchronous generators. In this connection, this paper proposed a test system consisting of 120 KV grid connected to a thermal plant and three Doubly-Fed Induction Generator (DFIG) - based wind farms. The modeling of the system is implemented on MATLAB/SIMULINK platform. An efficient pi controller scheme is used for the DFIG system for maintaining the desired active power and reactive power. The responses of the total system under healthy and faulty conditions are addressed. The obtained results are presented to exhibit the effectiveness of the controller and validate the performance of the grid interconnected test system.
