Abstract

The deterioration in the quality of the power supplied has the root cause of dilating gap between the supply and the demand. The occurrence of voltage sag and swell is predominant over other power quality issues like harmonics. The simulation of distribution network using FACTS devices for tempering the power quality issues is prevailing these days but there exist speculative theories which don’t provide effective and robust system on voltage stability and power quality control. This paper focuses on simulation of eight-bus system using D-STATCOM and DVR which is connected with closed loop PID and PI controller. The system is simulated to reduce the peak time, settling time and the steady state error thus proves to be effective in mitigating the voltage sag and swell occurring at the load point distribution system. The simulation is processed in the MATLAB software and the comparison of using PI and PID controller is tabulated and the system is implemented using the PIC16F84A micro-controller.

Keywords

Voltage Sag, Swell, PI controller, PID controller, closed loop.
