Virtual　synchronous　generator　control　can　realize　the　active　power　sharing　between　parallel　inverters　in　steady　state.　However,　the　difference　of　inertia,　damping　or　line　impedance　may　cause　active　power　overshoot　and　oscillation.　In　this　paper,　the　active　power　transient　process　during　load　transition　is　divided　into　two　stages.　The　characteristics　of　the　two　stages　are　analyzed　by　the　equivalent　circuit　model　and　the　small　signal　model　model　respectively.　On　this　basis,　the　transient　active　power　sharing　optimization　method　based　on　virtual　impedance　and　transient　damping　is　proposed.　Finally,　the　Matlab/Simulink　simulation　and　experimental　results　validate　the　availability　of　the　proposed　method.　©　2019,　Electrical　Technology　Press　Co.　Ltd.　All　right　reserved.
