Enhancing Renewable Energy Integration: Bidirectional DC-DC Converter for Grid-Connected V2G Systems

The integration of renewable energy sources into the grid is a key priority in achieving a sustainable and decarbonized energy system. Electric vehicles (EVs) can play a significant role in enhancing renewable energy integration through their ability to act as grid-connected storage devices. This study focuses on the utilization of a bidirectional DC-DC converter in grid-connected vehicle-to-grid (V2G) systems to enhance the integration of renewable energy. The research investigates the performance and benefits of a bidirectional DC-DC converter in facilitating energy exchange between the grid, EVs, and renewable energy sources. The converter allows for efficient bi-directional power flow, enabling EVs to function as mobile energy storage devices and actively participate in grid operations. The study analyzes the technical aspects of the bidirectional DC-DC converter, including its operating principles, voltage conversion capabilities, and power flow control strategies. It also evaluates the converter’s efficiency, power loss, and voltage regulation performance to ensure its optimal operation in grid-connected V2G systems. By utilizing the converter, surplus renewable energy generated during periods of high production can be stored in EV batteries. This stored energy can then be discharged back to the grid during peak demand periods or when renewable energy generation is low, helping to balance supply and demand and maximize the utilization of renewable energy resources.
