Abstract EN

The conventional voltage and frequency droop control strategy in grid-connected inverter suffers a major setback in the presence of disturbance by producing oscillations.

Adding a power differential term in droop controller is an effective way to address such drawback.

In this paper, grid-connected inverter’s small-signal models of the conventional droop control and the power differential droop control are established.

The eigenvalues of the models are then determined by system matrix.

The eigenvalues analysis is presented which helps in identifying the relationship between the system stability and controller parameters.

It is concluded that the damping ratio of dominant low-frequency eigenvalues increased and the oscillation caused by the disturbance is suppressed when a power differential term is added to the droop control method.

The MATLAB/Simulink models of grid-connected inverter with both control strategies are also established to validate the results of small-signal analysis.
