The continuity of the energy grid is the result of building a breed of ever-increasing demand for innovative electrocatalysis and the most effective solutions that qualifies the active sharing by end users in the balanced and trustworthy management of energy systems. One emerging prospect for such bidirectional exchange of electrical energy through the network and consumers is scope for the development of bidirectional energy trading among energy suppliers and owners of electric vehicle. It is proposed in this article to design a bidirectional, 3-phase, 2-stage off-board EV charger. The first step works as an AC/DC converter through the charging process, runs as 3-phase inverter and improves power factor while power is exchanged from the V2G. The next step is a DC/DC converter connected to first step via a DC-bus. A grid bypass filter is prepared to activate grid interconnection without noticeable problems in power quality. Suggested design and innovative infrastructure were examined during a simulation-based MATLAB software environment by connecting charger to a 3-phase micro-network and the results are consistent with the performance of suggested charging topology.

: The main components of Microgrids (MGs) consist of numerous Renewable Energy Sources (RESs) that utilize a variety of technologies built on power electronics. Nevertheless, it exhibits an erratic output, thereby resulting in various forms of power quality incidents. Consequently, there has been the establishment of standards and the implementation of mitigation strategies. Recent years have suggested several strategies and standards to address power quality difficulties caused by the integration of MG. expect the power quality to decline as the use of switching devices continues to increase. Additionally, these devices are particularly susceptible to damage. To experience a breakdown due to inadequate power quality, the globe is propelled by carbon emissions to substitute conventional electricity with as much renewable generation as is feasible. Researchers have been drawn to the aforementioned circumstances in order to find and propose mitigation approaches for power quality issues. The goal is to enhance the performance of MG that use renewable energy resources . This paper gives a review on power quality, standards and explains issue of power quality, harmonic mitigation techniques.
