Abstract

The dynamic equivalent circuit model of GEVSG grid-connected active power-angle is established, and the reason of GEVSG active power oscillations under different disturbances is revealed from the perspective of circuit energy flow. An active power oscillation damping strategy based on energy reshaping mechanism for GEVSG is proposed, and the parameter design method is given according to the second-order equivalent reduced-order control model. Both the Matlab simulation and experimental test platforms of a 100 kVA GEVSG grid-connected system are established, and the feasibility and effectiveness of the proposed control strategy are verified by using the simulation and experimental comparison results.
