A microgrid (MG) is a small-scale power system with a cluster of loads and distributed generators operating together through energy management software and devices that act as a single controllable entity with respect to the grid. MG has become a key research element in smart grid and distribution power systems. MG mainly contains different renewable energy sources (RESs) that use various technological advancements, such as power electronics-based technologies. However, it has an unstable output, thereby causing different types of power quality (PQ) events. As a result, standards and mitigation methods have been developed in recent years. To mitigate PQ issues due to MG integration, various methods and standards have been proposed over the last years. Although these individual methods are well documented, a comparative overview had not been introduced so far. Thus, this study aims to fill the gap by reviewing and comparing the prior-art PQ issues, solutions, and standards in MGs. We compare the main issues related to voltage sag, voltage swell, voltage and current harmonics, system unbalances, and fluctuations to ensure high-quality MG output power. The new technologies associated with MGs generate harmonics emission in the range of 2-150 kHz, thereby causing a new phenomenon, namely, supraharmonics (SH) emission, which is not sufficiently covered in the literature. Therefore, the characteristics, causes, consequences, and measurements of SH are highlighted and analyzed. The mitigation strategies, control, and devices of PQ issues are also discussed. Moreover, a comparison is conducted between the most popular devices used to mitigate the PQ issues in MG in terms of cost, rating, and different aspects of performance. This review study can strengthen the efforts toward the mitigation and standards development of PQ issues in MG applications, especially SH. Finally, some recommendations and suggestions to improve PQ of MG, including SH, are highlighted.

“…In power system and electricity grids the quality of power problems occurred like sag, distortion, harmonics in supply power as well as load energy. Photo -Voltaic (PV) and Fuel cell are sources to maintain dc link voltage and the quality problems in power can be reduced [2]. In the steel industries the non linear loads i.e especially furnaces are decreasing the power quality such as harmonics, fluctuations in power and power loss that also affect the other loads.…”

In this paper the power compensation for power system during faults in distribution line is described. The proposed system is designed by using the series and shunt APF based hysteresis control scheme to compensate harmonic distortion and control the system stability. Moreover, the system can be compensated the current as well as voltage simultaneously by using Unified Power Quality Controller (UPQC). Voltage Source Inverters (VSI) are connected in both the series and shunt. The main feeder is used to injecting power to these inverters using transformer and VSI compensate the imperfection line such as sag, interruption, swell, voltage unbalance. DC link voltage of the system is maintained at series and shunt operation. The proposed system is verified successfully and tested using MATLAB/Simulink.

Samal and Hota [5] "have presented the design/simulation on a shunt active power filter for harmonics and reactive power compensation technique in MG. To ensure stable operation and improve the system performance of MG in island mode SAPF is used at point of common coupling (PCC), which compensates the harmonics from the load current.

“The increased penetration of Distributed Energy Resources (DER) is inspiring the entire design of conventional electrical power system. “A Microgrid (MG) includes distributed generation, loads, energy storage, and a control system that is competent of working in grid-connected mode and/or islanded mode. Power quality (PQ) problems are one of the major technical challenges in MG power system. To get better PQ of energy supply, it is essential to analyze the harmonics distortion of the system. Moreover, harmonic distortion in a MG networks has significantly reduced PQ, which affects the stability of the system. In order to diminish the harmonics, shunt active power filter (SAPF) has been extensively useful and it is verified to be the best solution to current harmonics. The present paper proposes the mitigation of harmonics of a MG system using shunt active power filter (SAPF). However, the SAPF is employed for reimbursing the harmonics concurrently in the distribution system. The proposed model is developed in MATLAB/Simulink and the result obtained validates the superiority of proposed technique over others in terms of harmonics elimination.”
