Abstract
The short-term frequency support will be provided through inertia control of doubly-fed induction generator (DFIG) wind turbines when grid frequency changes, so as to meet the grid frequency deviation requirements. In this paper, a novel inertia control strategy of DFIG wind turbines, which is based on slip feedback controller with incomplete differential PD algorithm, is proposed. Compared with the existing supplementary frequency differentiation inertia control and supplementary frequency proportion differentiation inertia control, the proposed control strategy can achieve better inertial response performance. A simulation model is built on to demonstrate the advantages of the proposed method, simulation result shows that the slip feedback inertia control strategy can more effectively restrain the grid frequency fluctuations with a smoother and shorter recovery process.
