Solar Power Charging of Electric Vehicle Along with the Implementation of Vehicle-To-Grid (V2G) Technology

Abstract

Reducing pollution in the environment is the most important topic of the present times. Pollution mainly arises from the burning of fossil fuel which emits CO2 and other harmful gases in the environment. The transportation sector is introducing technologically advanced Electric Vehicles (EVs) which are eco-friendly. EV integration to the grid is the attraction of many researchers and engineers around the world due to the rapidly growing numbers of EVs in the global market. The use of EVs in the grid will play an important role in future smart grid technology. But EVs charging puts significant load demand on the grid as well as uneven and uncoordinated charging creates disturbance in the grid. In order to reduce the burden on the grid, the EVs can be charged by Renewable Energy Resources (RESs). Solar is the most widely available renewable energy source. Solar charging stations can be installed at homes, offices, parking lots, public areas and isolated areas. The proposed system in this chapter is designed in the MATLAB Simulink environment in which Electric Vehicle (EV) is charged in a standalone solar power charging station and this EV is integrated into the grid when the solar power is unavailable. The use of a DC–DC bidirectional converter with appropriate controlling technique enables the transfer of power from EV to the grid whenever there is demand. The benefits and limitations of integrating EV in the power systems have been discussed in this chapter.KeywordsElectric Vehicle (EV)Solar-to-Vehicle (S2V)Vehicle-to-grid (V2G)DC–DC bidirectional converterDC–AC converter
