Sags/Swell Compensation Based on Voltage Controlled Distributed Energy Resources (Vc-Der)
This paper shows compensation techniques of the power quality issues like sags/swells, harmonics and its severe
impact on non linear loads or sensitive loads. The Distributed Energy Resources (DER) has become popular as a cost
effective solution for the protection of sensitive loads against quality issues. Some power quality disturbances come in
electrical systems are voltage sag, swell, notch, spike and transients etc. The voltage sag and swell is very rigorous problem
for an industrial customer which needs urgent attention for its compensation. The proposed control scheme is simple to
design. The performance of the proposed method can verify with MATLAB/SIMULINK method.
Keywords - Power Quality, Voltage Sag/swell, Distributed Energy Resources (DER), Control Strategy, sensitive load.
