Abstract: This paper presents a novel simple controller for distribution static compensator (DSTATCOM) to achieve balanced source currents with power factor correction and harmonics mitigation in a three-wire distribution supply system under various supply and load conditions. The proposed algorithm rearranges the switching times for each device of the voltage source converter to compensate the reactive power demand by the nonlinear or unbalanced reactive loads. Simulation results demonstrate the optimised performance of the DSTATCOM after implementing proposed control algorithm. The proposed control algorithm applied to an improved power quality PWM AC to DC converter as reported in the literature is extended to the bidirectional converter operating in inversion mode. The PWM converter with proposed control algorithm operated as an inverter is made to work as DSTATCOM for perfect load compensation.

Keywords: distribution static compensator; DSTATCOM; harmonics mitigation; power factor correction; nonlinear load; point of common coupling.
