Abstract

Aiming at the challenge of coordinated optimization between transient oscillation suppression and steady-state deviation elimination caused by the introduction of damping coefficients in virtual synchronous generator (VSG) control

an active power control method for virtual synchronous generator (VSG) based on fractional-order proportional-integral (FO-PI) damping regulation was proposed. First

the inherent contradiction mechanism of the damping coefficients between dynamic response and steady-state accuracy in conventional VSG control strategies was analyzed. Subsequently

a fractional-order proportional-integral damping regulation module was embedded into the traditional control architecture. This module generated non-zero damping power during transient processes to suppress active power oscillations

and automatically eliminated damping power during the steady-state operation to eliminate steady-state deviations. The effectiveness of the proposed strategy in suppressing transient oscillations and eliminating steady-state deviations was verified through Matlab/Simulink simulations.The results show that the proposed control method can effectively suppress oscillations and overshoot caused by sudden changes in power and frequency

eliminate steady-state errors under grid frequency deviations

and solve the problem of balancing dynamic response and steady-state accuracy in traditional control methods.
