چكيده لاتين :
In this article, the control of interfaced converters of distributed generations (DGs) in order to improve microgrid power quality with emphasis on voltage unbalance is considered. The control scheme of these converters is coordinated so that the DGs contribute to voltage unbalance compensation proportional to their rated power and by considering the residual capacity of each DG. The control structures presented in this article are classified into two categories: voltage_controlled mode (VCM) control scheme and current_controlled mode (CCM) control scheme. VCM units using capacitive virtual impedance contribute to voltage unbalance compensation, while in the control scheme of CCM units, a virtual admittance is implemented in order to compensate voltage unbalance with considering the residual capacity of the inverter. Also, VCM and CCM units contribute to reactive power sharing by droop and reverse droop control methods, respectively. Droop coefficients are adjusted considering the limited capacity of these inverters and the unbalance power. Finally, the results were then presented to show the effectiveness of the proposed control structure at different stages.
