Abstract

The Vehicle-to-Grid (V2G) bidirectional power transfer system is an innovative concept that allows electric vehicles (EVs) to not only consume electricity from the grid but also supply power back to it. This system enables a sustainable and efficient way of managing energy resources by utilizing the EV battery as a mobile energy storage unit. The objective of this paper is to design and simulate a V2G bidirectional power transfer system, analysing the dynamic interaction between electric vehicles and the grid under various operating conditions.

The proposed model integrates key components, such as the EV battery, bidirectional converter, and grid connection system, with the control strategies required to ensure safe, efficient, and reliable power transfer. A comprehensive simulation framework is developed using advanced modelling tools (e.g., MATLAB/Simulink), which allows for real-time assessment of the power flow, voltage regulation, frequency stabilization and grid support capabilities. The performance of the system is evaluated based on factors like charging/discharging efficiency, energy transfer rates, grid impact and response to fluctuating renewable energy sources. Additionally, the study investigates the economic benefits of V2G systems, including energy cost savings, potential revenue generation for EV owners, and reduced grid dependency [1].
