Abstract

Droop control is basic control method for load current sharing in dc microgrid applications. But the line impedance disturb the load current sharing in the droop control system. To reduce the influence of line impedance, large droop gain is needed but that increase the dc voltage deviation. The dc voltage deviation can be compensate by hybrid control method. In the steady state, the dc voltage is controlled well in nominal voltage but in the transient condition such as load change and communication delay, the increased droop gain makes the voltage fluctuation large. In this paper, large signal modelling and small signal modelling is performed.
