A Review on Charging Control and Discharging Control of Plug-in Electric Vehicles in the Distribution Grid

The potential of electric automobiles to discharge their batteries to the power grid (namely V2G technology) is discussed in this article as a way to lessen pollution and provide extra services, including income generation and grid reliance. The widespread use of electric cars might provide difficulties for the electrical infrastructure, such as power outages, overloading of transformers, and variations in bus voltage. The electrical grid and electric cars are connected through a middleman called an aggregator. This article investigates novel technologies and coordination mechanisms to control the discharging and charging of electric cars. In addition to that, Various optimization techniques are reviewed and also try to explain about challenges and future advances in the EV charging process and discharging process.
