Abstract: To address the frequency fluctuations and poor dynamic performance in photovoltaic (PV) hybrid energy storage grid systems, a collaborative control strategy based on frequency division and adaptive virtual synchronous generator (VSG) is proposed. In this strategy, the frequency division is used to realize the bus voltage stabilization and power peak shaving, thereby reducing the impact on energy storage devices, and extending the battery service life. On this basis, a VSG equivalent model is constructed, and an adaptive parameter adjustment method based on system dynamics is designed. A coordinated adjustment mechanism for inertia and damping is proposed, and a damping ratio constraint is introduced to realize dynamic coupling adjustment of the two and overall optimization of the system. In comparison with conventional VSG strategies with independent parameter adjustments, the proposed method can enhance the adaptability and robustness of the system. The simulation experiments verify the suppression effect of this strategy on the frequency and power fluctuations under various operating conditions as well as the feasibility of its grid-connected operation by the simulation experiments. The results show that the proposed method can effectively enhance the dynamic response capability and frequency stability of the system, and exhibit excellent control performance and robustness.
