Electrical power quality (EPQ) in distribution systems is a critical issue for commercial, industrial and residential applications. The new concept of advanced power electronic based Custom Power Devices (CPDs) mainly distributed static synchronous compensator (D-STATCOM), dynamic voltage restorer (DVR) and unified power quality conditioner (UPQC) have been developed due to lacking the performance of traditional compensating devices to minimize power quality disturbances. This paper presents a comprehensive review on D-STATCOM, DVR and UPQC to solve the electrical power quality problems of the distribution networks. This is intended to present a broad overview of the various possible DSTATCOM, DVR and UPQC configurations for single-phase (two wire) and three-phase (three-wire and four-wire) networks and control strategies for the compensation of various power quality disturbances. Apart from this, comprehensive explanation, comparison, and discussion on D-STATCOM, DVR, and UPQC are presented. This paper is aimed to explore a broad prospective on the status of D-STATCOMs, DVRs, and UPQCs to researchers, engineers and the community dealing with the power quality enhancement. A classified list of some latest research publications on the topic is also appended for a quick reference.

Mostly the power quality is affected due to the sensitive loads. These power quality issues create many disturbance like voltage sag, voltage swell, harmonic distortion and transient voltage. Due to the development of the power electronic technology, several mitigation techniques was emerged. From the wide range of mitigation technique we have taken a Dynamic Voltage Restorer (DVR) to protect from the sensitive loads. But it suffers with some of the drawbacks like, increased voltage limits, less capacity on compensating the line voltage and high transients. To overcome these drawbacks the DVR used in this research contains 3 ph six leg inverter and a LC filter to remove the unwanted frequencies. Moreover, a Space Vector Pulse Width Modulation (SVPWM) control strategy is used to manipulate the six leg power switched inverter, based on the space current and voltage converter switching. This research is intent for less expensive approach for this SRF theory helps to avoid the excessive controller in all three phases. Instead the d and q control strategy requires only two controller for all three phases. The performance analysis of the proposed system is evaluated by analyzing the power consumption and efficiency. Moreover the proposed system is compared with existing works related to this research work.

“…This approach provides the best control performance and less response time compared with conventional PI controller under different disturbance. Sundarabalan and Selvi proposed DVR using real coded genetic algorithm–optimized PI and fuzzy logic (FL) controller for improving power quality. The suggested DVR compensates balanced and unbalanced voltage sag/swell, reduces THD, and reduces injection of active power into the grid.…”

Summary In the distribution power system, voltage sag and swell are the critical issues. The impact of this issue creates major economic loss and power loss in the distribution system. There are several detection methods available, mainly, connecting the FACTS devices such as Static Compensator (STATCOM), Unified Power Quality Conditioner (UPQC), and dynamic voltage restorer (DVR) at the point of sag or swell. DVR is one of the custom power devices to mitigate the voltage sag and swell. Sliding mode controller (SMC) is proposed in the paper, which is used to regulate the DVR to mitigate the voltage sag issue. Particle swarm optimization (PSO) algorithm is utilized in this work to find the optimum value of SMC parameters, namely, Kp and Ki, with the objective of minimizing the integral square error (ISE). A simple two feeder distribution network with DVR is developed in MATLAB‐SIMULINK to assess the performance of DVR under various faults and disturbed situations. The mitigation level and THD values of PSO‐optimized SMC‐based DVR results are compared with the PI controller–based DVR, PSO‐optimized PI controller DVR, and SMC‐based DVR. At last, in the proposed method, the trial is taken by adding a renewable energy resource, that is, PV farm at 400‐kW power rating. The solar energy is integrated with the existing distribution system, and the results are incorporated. Simulation results show that the PSO‐optimized SMC‐based DVR can compensate the voltage sag and swell and also reduce the load voltages efficiently.
