Industries driven by electric power require controlled and improved power quality for the optimal exploitation of resources. However, certain crucial issues greatly influence power quality, causing monetary losses to both the utility and customers. Numerous custom power devices are available to compensate for power quality issues; however, these devices alter the parameters of the transmission and distribution systems. Hence, a dynamic voltage restorer (DVR) is adopted in this study, which mitigates voltage disorders by establishing the desired quality and voltage level demanded by any sensitive load. The DVR adopts a 3ϕ four-switch voltage-source inverter (VSI) that acts as a cost-effective solution with a reduced number of switches. The cuckoo search algorithm (CSA) was utilized in this study as it solves multiple optimization issues with ease of implementation. Because it is robust to variations in the system, it significantly aids in enhancing the efficiency of the DVR by compensating for the variations in voltage and minimizing the total harmonic distortion (THD). The entire work was verified in MATLAB/Simulink to demonstrate the effectiveness of the introduced technique in smoothing the distorted voltage. The proposed approach achieved an efficiency of 92.6%witha simulation THD of 2.8% and hardware THD of 2.95%.INDEX TERMS DVR, CSA, Power quality, voltage swell, injection transformer, voltage sag.

“…Regarding the growth of electronic inverters-based PV systems, the distribution network tested through two-way energy ow can create a new set of power quality challenges such as voltage quality and harmonics in the systems PV connected to the distribution network with the presence of loads at the common connection point (PCC) [4,[5][6][7][8]9,10]. The photovoltaic systems e ciency is related to the uctuation of solar radiation, caused by the weather conditions variation which includes, the passingclouds through the various seasons, the characteristics of the PV erection sites and the PV array erection types ( xed or tracked).…”

This paper presents an experimental voltage quality analysis affected by passing clouds based on results attained from monitoring a 9.5-kWp photovoltaic grid connected. This system is composed of three 3.2 kWp subsystems installed on the flat roof of the Renewable Energy Development Institute (CDER) in Algeria. In this paper we analyzed and evaluated Short-term and long-term voltage flicker indexes (Pst,Plt), power ramp event on voltage quality, harmonics caused by inverter and by the loads connected to the PCC, and very short voltage variation (VSV). The power quality parameters at the inverter output side have been measured using CA8335 power quality analyzer. The results show that the change in the density of the passing clouds has a linear relationship with the change in the intensity of the ramp event on the power generated by the PVS. Moreover, in the case of a bidirectional electrical network and with the presence of non-linear loads, the flicker recorded has exceeded the legal limits, due the second-order harmonics effects generated by non-linear loads and the level impedances at the grid and the PV system connection point. The concluded results obtained can be an additional profit of for the electricity distribution networks in Algeria, upon in the light of the diffusion of promoting photovoltaic systems.

“…However, when implementing or selecting an electrical generation system, high robustness should be considered in the face of voltage variations, current or power outage, high reliability (appropriate waveforms for both voltage and current and supply of electrical energy in all moment), and an adequate power capacity for the design requirements, in order to obtain a good electrical production performance. These systems generate many transient, due to the variation in the solar radiation, and therefore a non-continuous supply, leading to power quality issues [ 3 , 4 ]. A significant part of the photovoltaic installations are the power conditioning system, also known as power converters, which transform the electrical power, generated by the photovoltaic panels, into a signal suitable for use.…”

The use of renewable energies sources is taking great importance due to the high demand for electricity and the decrease in the use of fossil fuels worldwide. In this context, electricity generation through photovoltaic panels is gaining a lot of interest due to the reduction in installation costs and the rapid advance of the development of new technologies. To minimize or reduce the negative impact of partial shading or mismatches of photovoltaic panels, many researchers have proposed four configurations that depend on the power ranges and the application. The microinverter is a promising solution in photovoltaic systems, due to its high efficiency of Maximum Power Point Tracking and high flexibility. However, there are several challenges to improve microinverter’s reliability and conversion efficiency that depend on the proper control design and the power converter design. This paper presents a review of different control strategies in microinverters for different applications. The control strategies are described and compared based on stability, dynamic response, topologies, and control objectives. One of the most important results showed that there is little research regarding the stability and robustness analysis of the reviewed control strategies.
