“…Furthermore, the voltage control techniques used for DVR may be categorized as either hysteresis voltage control methods [21][22][23][24][25] or pulse width modulation (PWM) control methods [26,27]. The first category is simple to implement and requires no knowledge of system parameters [3], but has uncontrollable high switching frequency.…”

The use of certain electrical equipment connected to conventional power systems has raised concerns regarding the quality of the power system. Some equipment has been perceived to be unequipped to sustain the surges, faults, and distortions in traditional distribution systems. Common voltage issues exist, such as imbalance, harmonic distortion, sag, and swell. Such issues are usually contained using a dynamic voltage restorer (DVR). In this study, the determination of voltage references for DVR based on a robust and simple detection method of positive and negative sequence components is analyzed. This method detects the components in real time. With the proposed method, either the reference load voltages can be generated, or the reference DVR voltages can be generated, depending on which voltages are controlled. Moreover, contrary to other methods, the proposed technique avoids the use of phase-locked loop (PLL) and vector transformation. The voltage compensation technique controls the DVR in real time to prevent steady-state and disturbance conditions at the load side. The proposed system is evaluated by simulation and experimentation under several steady-state and transient cases. Finally, the proposed control is compared with common control methods.

“…This work evidently mentioned that the bonus of enforcing the UPQC into the power system, when compared with an APF. The control algorithm is proposed to quench the harmonics, but with the requisite of increased memory space [1]. The work "A Low Cost High Performance UPQC for Current and Voltage Harmonics Compensations" carried out by Quoc-Nam Trinh along with Hong-Hee Lee from Ulsan University -Korea suggests the use of low cost, high performing UPQC devices in a power system.…”

An Unified Power Quality Conditioner (UPQC), is a combination of shunt and series Active Power Filter (APF), has become a standard accepted solution in the area of current and voltage harmonics mitigation of a power system network. This paper furnishes a comparative analysis of the power quality enhancement and optimization in positioning for three different VSI based UPQC system configurations namely: 3P3W UPQC topology, 3P4W UPQC based on 2C shunt inverter topology and 3P4W UPQC based on 4L shunt inverter topology, all supported with the Fuzzy Logic Controller (FLC), placed at different locations in a standard IEEE 14 bus system. Simulation results using MATLAB/SIMULINK provides the optimal position of UPQC for mitigating the harmonic issues in the standard IEEE 14 bus system.
