A strategy of grid-forming (GFM) energy storage frequency regulation control based on an improved linear active disturbance rejection control (LADRC) is proposed to help overcome two problems: the frequency stability of a power system with a high proportion of wind power penetration; it is difficult to take into account the interaction between parameters in the process of frequency regulation of a wind-storage combined system, resulting in poor frequency regulation control performance of the system. First, using the fast control of the diagonal frequency of the traditional application LADRC, active power difference compensation is introduced to accelerate the response speed of active power instructions and eliminate parameter cross-coupling. From the influence law of the parameters of the grid-forming energy storage frequency regulation control strategy, a small-signal model of angular frequency and reference power to the output power is analyzed. The transfer function of the control link is deduced to optimize the frequency regulation performance of the system. Finally, a simulation model of the combined wind storage system is built on the Matlab/Simulink simulation platform, and the changes of the power grid frequency and energy storage output in different working conditions are compared and analyzed with different control strategies. The results show that the proposed control strategy effectively improves the support ability of the combined wind storage system to the power grid frequency in complex working conditions.
