The Role of Smart Charging and Vehicle-to-Grid (V2G) Technology in Energy Optimization

Abstract

The rapid growth of electric vehicle (EV) adoption presents both operational challenges and strategic opportunities for modern power systems. Uncoordinated charging can intensify peak demand, strain distribution networks, and complicate renewable energy integration. However, smart charging and vehicle-to-grid (V2G) technologies offer innovative solutions to optimize energy use, enhance grid flexibility, and support low-carbon energy transitions. the role of smart charging systems and V2G technology in improving energy optimization within increasingly electrified transport networks. Smart charging enables dynamic control of charging schedules based on grid conditions, electricity pricing, and renewable generation availability. By shifting demand to off-peak periods or times of high renewable output, it reduces peak load pressure and improves system efficiency. Vehicle-to-grid technology extends this capability by enabling bidirectional power flow between EV batteries and the grid. Through V2G, parked vehicles can function as distributed energy storage units, providing frequency regulation, peak shaving, and backup power services. This capability enhances grid stability and allows greater penetration of variable renewable energy sources such as solar and wind.
