摘要
We present a feedback control scheme for a hybrid bidirectional interlinking converter of an alternating current (AC)/direct current (DC) microgrid. The output voltage and current are measured which allow us to design a suitable control for the power flow. We propose a robust droop control strategy to cater for the uncertain voltage and frequency droop caused by load variations. The proposed droop controller takes into account the unmodeled load dynamics as well as the power switching transients between AC/DC microgrids. A conventional current controller followed by a sliding mode controller (SMC) are able to maintain the power stability in different operating conditions. Simulation results are presented which show performance of the proposed control scheme.
