“…The VSI has been traditionally employed in the DVR configuration [9]. In [10], the performance of the DVR system based on the VSI is investigated, and simulation is performed for voltage sag and voltage swell situations. The DVR system can easily handle and keep the voltage balanced and constant, which is required by the load.…”

“…The advantages and disadvantages of modified DVR configurations, including IDVR, TDVR, DVR based on direct AC/AC converters, and PV DVR are provided in Table 10 [175 -183,186-188]. High initial material and installation costs, no solar power at night, lower solar power on cloudy days, lower solar power in the winter months, producing DC and need for DC/AC converters The integration of DGs and DVR has become popular [190][191][192]. This is even important for Low-Voltage Ride-Through (LVRT) capabilities in wind turbines.…”

“…In grid-connected PV systems, voltage sags can be caused by Partial Shading Conditions (PSC) due to reasons like passing clouds, nearby buildings, and growing trees. In this case, Maximum Power Point Tracking (MPPT) methods are used to extract the maximum PV power [200,201] and as well as that the DVR is connected in series with PCC to compensate and mitigate voltage sags due to PSCs [18,192]. An in-depth review of different control strategies and algorithms for the integration of DGs with distributed FACTS like DVR and DSTATCOM has been provided in [202].…”

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.

The pursuit of the MPP and the control of the inverter play a very important role in a PV system connected to the utility grid. In this paper, an intelligent method is used to regulate the DC bus voltage. The hybrid neuro-fuzzy algorithm HNF type is used. The latter is a combination of fuzzy logic and neural networks. The PV chain, dependent on climatic conditions needs mechanisms to optimize the power it delivers, but also the injection of good quality energy to the utility grid. Among these mechanisms, there is the control of the three-phase inverter: grid currents control and DC bus voltage regulation which is based on the HNF. The implementation of the model and its simulation under Matlab/Simulink indicates that only the active power is injected into the grid. They also reveal that the HNF has a response time (Rt) of 0.097 s, a rise time (rt) of 4.30610-3 s and a THD of 0.85% compared to the modified PID which has a response time of 0.659 s, a rise time of 0.156 s and a THD of 2.74%.
