Advanced DC-DC Bidirectional Converter with Three Ports for Use in Vehicle-to-Grid Applications

The goal of the project is to create a sophisticated three- port bidirectional DC-DC converter for use in vehicle-to-grid (V2G) systems by combining solar and wind energy with electric vehicles, the converter allows power to go in both directions between EV batteries and the grid as well as renewable energy sources. With the use of advanced control algorithms, it maximizes energy exchange, EV charging and discharging, and grid stability. The converter aims to transform V2G with its clever energy-sharing strategy combining solar, wind, and battery storage, technology, increasing sustainable transportation, strengthening grid resilience, and speeding up the incorporation of renewable energy. The utilization of single-stage topology in three-phase Z-source inverters has made them a viable option for voltage boosting. Furthermore, because they can function as rectifiers in both directions, they are very well suited for a wide range of transportation electrification applications, including Vehicle-to-Grid (V2G) chargers. Multiport converters, bidirectional buck-boost converters for voltage regulation, hybrid energy storage systems combining batteries and ultracapacitors, advanced digital control algorithms, virtual synchronous generators (VSGs) for grid stability, resonant converters for high- frequency power conversion, and soft-switching techniques to minimize losses are some of the existing methods for bidirectional DC-DC converters in Vehicle to-Grid (V2G) applications. By maximizing power flow between EVs, solar, wind, and the grid, these solutions enable effective energy integration and exchange. The suggested system includes a bidirectional DC-powered advanced three-port.
