چکیده:

Recently, there is an increasing interest of using distributed generators not only to inject power into the grid, but also to enhance the power quality. In this paper, a control method for distributed generation (DG) systems to compensate voltage unbalances is proposed. The method can be used in both islanded and grid-connected operation modes of the DG. In this approach, active and reactive power control loops are considered to control the power injected by the DG. Also, a virtual impedance loop and voltage and current proportional-resonant controllers are included. Simulation results show the effectiveness of the proposed method for compensating voltage unbalance to a determined level.
