A strategy for voltage harmonics suppression is proposed to upgrade existing grid-connected inverters. It utilizes the already available measurement of the voltage at the point of common connection and the inverter output current. As a result, on top

This paper considers a single-phase grid-connected converter in the presence of non-linear loads. A local voltage support strategy is proposed to compensate the harmonics caused by the loads. This is an added feature implemented in parallel with a co
