Power system frequency control using Type-4 wind turbine generators

Abstract

System frequency response can be negatively impacted by significant penetration of wind generation. This paper studies the effects of integrating Type-4 full converter wind turbine generators (WTG) on the frequency response of a test system. A controller that enables frequency response in a Type-4 WTG is then proposed to restore and improve the frequency regulation of the system. The design and performance of the proposed controller are demonstrated using linear analysis and nonlinear simulation. The results are then compared with those for Type-3 DFAG frequency regulation technology.
