Usually, the conventional droop method is utilized for the control of autonomous micro-grids. In islanded micro-grids (MG), due to the effects of mismatch in line impedance, the reactive power cannot be shared by using a conventional droop method. In this paper, a method is proposed to improve the reactive power sharing. In this method, the micro-sources are acted with P-w& Q-E droop characteristics; then, the reactive power sharing error is reduced to modify Q-E characteristic on the periodic time distances. The feasibility and effectiveness of the proposed method are validated using simulation on SIMULINK/MATLAB software.
