“…2) Case 2 When the voltage of the DVR V DVR2 is injected with a phase angle γ and magnitude to guarantee the load voltage V L2 at the desired magnitude with a phase angle shift δ, the resulting load current I L2 will have a corresponding phase angle shift δ as illustrated in Fig. 1 [11] - [19]. The angle between I L2 and V L2 remains unchanged when the load is not changed.…”

“…The operation principle of the DVR is to inject a voltage of specific phase angle and magnitude in series with the distribution line in order to form a rated sinusoidal load voltage [5] - [19]. In the literature, the DVR can operate in various compensation modes, including the pre-sag mode [7], [8], the in-phase mode [9], [10], the self-supported mode [11]- [16], and the energy-optimized mode [17] - [19]. Specifically, besides the ability to maintain the desired sinusoidal waveform at the load side, the DVR can optimize the energy handled by it, or operate at capacitor-supported mode without DC link active power supply.…”

This paper investigates the ability of correcting the power factor at the point of common coupling (PCC) of the source side using dynamic voltage restorer (DVR). By applying the phase angle control (PAC) method, the DVR compensating voltage will be injected with a specific phase angle and magnitude in series with the transmission line, which leads to a power factor angle shift of the resultant load voltage. As a result, the source voltage is always in phase with the source current under different load conditions, which means that the power factor correction is achieved at the PCC of the source side. A laboratorial prototype of the DVR is utilized to verify the proposed control algorithm. The experimental results validate that an approximate unity power factor can be maintained at the source side. Index Terms--Dynamic voltage restorer (DVR), voltage sag and swell compensation, phase angle control (PAC) method, power factor correction.

“…A comparison between feedback, feed-forward, and composite controllers is provided in Table 9 [138]. The calculated DVR voltage or load voltage in the feedback controller is affected by a voltage controller, like Proportional-Resonant (PR) [139], H infinity ( ) [140,141], Repetitive [67,142,143], Predictive [7,144,145], combined Feed-Forward and State Feedback [146], State Variable [147], Feedback Linearization [148], Sliding Mode (SMC) [149][150][151][152], and Metaheuristic Algorithms like Fuzzy Logic (FLC) [95,153,154], Hybrid Genetic Algorithm (GA) and FLC (GA FCL) [155], Cuckoo Search (CS) [156], Chaotic Accelerated PSO (CAPSO) [157], Artificial Neural Network (ANN) [46,158,159], to name just a few.

Power quality is a pressing concern and of the utmost importance for advanced and high-tech equipment in particular, whose performance relies heavily on the supply’s quality. Power quality issues like voltage sags/swells, harmonics, interruptions, etc. are defined as any deviations in current, voltage, or frequency that result in end-use equipment damage or failure. Sensitive loads like medical equipment in hospitals and health clinics, schools, prisons, etc. malfunction for the outages and interruptions, thereby causing substantial economic losses. For enhancing power quality, custom power devices (CPDs) are recommended, among which the Dynamic Voltage Restorer (DVR) is considered as the best and cost-effective solution. DVR is a power electronic-based solution to mitigate and compensate voltage sags. This paper provides a thorough discussion and comprehensive review of DVR topologies based on operations, power converters, control methods, and applications. The review compares the state-of-the-art in works of literature, and comparative study on power quality issues, the DVR principle along with its operation modes, the DVR components, the DVR topologies based on energy storage, the DVR topologies based on single-/three-phase power converters, and the DVR topologies based on control units that have different control processing stages. Furthermore, modified and improved configurations of the DVR, as well as its integration with distributed generations, are described. This work serves as a comprehensive and useful reference for those who have an interest in researching DVRs.

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.
