Improved active and reactive power sharing on distributed generator using auto-correction droop control

This paper presents a power-sharing scheme for distributed generators (DG). It performs auto-correction droop control under grid disturbances or sudden changes in local load. The DG injects active power with zero reactive power into the standard grid in the grid-connected operation mode. However, wh...
