Abstract: This paper presents a new meta-heuristic approach to control and generates reference currents and voltages for a Dynamic voltage restorer (DVR) to mitigate major power quality disturbances. The major disturbances that affect power quality (PQ) are voltage events such as voltage sag/swell. The synchronous reference frame (SRF) theory is used to generate the reference voltages, whereas differential evolution (DE), hybrid differential evolution (HDE), variable scaling hybrid differential evolution (VSHDE) is used to evolve proportional gain (Kp) and integral gain (Ki) values of the PI controller. The DVR comprises of voltage source converter connected to series injection transformer. Gating pulses required by the voltage source converter (VSC) of DVR is generated with the pulse width modulation (PWM) Technique. Effectiveness of the proposed work is validated by conducting simulations in MATLAB/SIMULINK software.
