This paper proposes a reliable and effective voltage control method using modified voltage droop control in low voltage (LV) distribution system when serious voltage problem occurs. The proposed method changes the droop control mode from conventional droop control to modified droop control and vice versa. It determines mode change condition to maintain the point of common coupling (PCC) voltage within voltage dead band. The numerical expressions of Ihe proposed method are presented and it is verified through the corresponding PSCAD based computer simulation.
