Traditional virtual synchronous generator (VSG) control strategies suppress power oscillations by adjusting inertia and damping coefficients. However

there is a trade-off between power oscillation suppression and system dynamic performance in conventional control strategies. To address this issue

a coordinated JDL adaptive control strategy based on virtual inertia J

virtual damping D

and virtual inductance L is proposed to suppress VSG power oscillations and enhance power response speed. First

the influence of J

D

and L on the damping characteristics of the VSG control system is analyzed. Then

instead of using the conventional frequency deviation and frequency deviation rate

three parameters

i.e.

VSG output power deviation

output power change rate

and grid frequency deviation

are introduced. Based on these three parameters and power oscillation curve

JDL adaptive control rules are formulated. Finally

Simulink simulations are conducted to compare the proposed coordinated JDL adaptive control strategy with traditional parameter adaptive control and fuzzy adaptive control strategies. The results verify the effectiveness and applicability of the proposed control strategy in suppressing power oscillations and improving dynamic performance.
