Abstract:
To address the frequency fluctuation issues caused by large-scale wind power integration, this paper proposes an integrated control strategy that combines wind turbine adaptive inertia control (releasing rotor kinetic energy) with energy storage system dynamic droop control for primary frequency regulation. The MATLAB/Simulink simulation results demonstrate that compared with conventional virtual inertia control, the proposed wind-storage coordinated control strategy significantly improves power system frequency stability, particularly in terms of frequency nadir and rate of change of frequency.
