摘要

Abstract

Power inverter adopting virtual synchronous generator (VSG) control can provide inertia support for distributed generation systems. However

it cannot take into account the dynamic regulation characteristics of frequency. Thus

when the system encounters a sudden change in load or disturbance

the dynamic process of frequency regulation will be greatly influenced. In view of this issue

an improved VSG control strategy based on a coordinated self-adaptive (CSA) method is proposed. The time domain analysis method is used to study the influences of virtual inertia and damping parameter perturbation on the system steady and dynamic performances. Furthermore

in order to make the control strategy suitable for large load changes and suppress frequency variations beyond the limit

the secondary frequency modulation is introduced into the control loop. Through the coordinated adaptive control of virtual inertia

virtual damping and frequency modulation

the dynamic performance of VSG frequency regulation can be obviously improved. Simulation and experiment results have verified the effectiveness of the proposed CSA control strategy.
