Balance control of grid currents for UPQC under unbalanced loads based on matching-ratio compensation algorithm

Abstract In three-phase four-wire systems, unbalanced loads can cause grid currents to be unbalanced, and this may cause the neutral point potential on the grid side to shift. The neutral point potential shift will worsen the control precision as well as the performance of the three-phase four-wire...
