Hybrid microgrid consists of AC and DC grids, in which the interlinking converter is used to connect AC and DC microgrids. The droop control scheme is widely applied to hybrid microgrid control including interlinking converter because it can be used to control power in hybrid microgrid without communication. However, the existing steady-state error in conventional droop control might affect to the power quality of sensitive load. Therefore, the improved droop control scheme is proposed in this study, in which the steady-stated error is removed by using an additional PI regulator. Various simulation scenarios in term of load variations are performed in the MATLAB/Simulink environment to verify the control performance of proposed control scheme. Simulation results show that the frequency and DC voltage are controlled stably by using improved droop control scheme.
