With the widespread use of harmonic generating devices, the control of harmonic currents to maintain a high level of power quality is becoming increasingly important. An effective way for harmonic suppression is the harmonic compensation by using active power filter. This paper presents a comprehensive...
Within the new strategy, the photovoltaic array can generate relevant active power according to the depth of the grid voltage dip to keep power balance between the two sides of the photovoltaic inverter. A feed-forward compensation reflecting the instantaneous current injecting into the direct current...
