An adaptive virtual inertial damping control for wind farm integrated energy storage system
In this paper,an adaptive virtual inertial-damping control method of battery energy storage for maximum wind power point tracking is proposed to increase the frequency stability of wind farms. First,adjustment coefficients of both the inertia control parameter and damping parameter are introduced to the virtual synchronous control strategy. Then,the value range of both control parameters is given by small signal analysis. Finally,based on the combined wind and storage system,the effectiveness of the control method proposed in this paper is verified when facing different types of faults. The results show that compared with the traditional virtual synchronous control method,the proposed method can significantly improve the frequency stability of the merging points,and realize the adaptive smooth adjustment of inertia and damping.
