| Abstract [eng] |
Vehicle-to-Grid (V2G) technology enables electric vehicles to not only draw energy from the power grid but also return stored energy back to it, making them active participants in grid balancing. This thesis analyzes the potential of V2G technology in the system services market, examining its technical operating principles, potential impact on electric vehicle batteries, and deployment challenges. A simulation model adapted to Lithuanian grid parameters was developed in the MATLAB Simulink environment. Using this model, simulations were conducted with varying numbers of V2G-capable electric vehicles, observing grid frequency behavior and battery response under changing load conditions. The simulation results demonstrated that increasing the number of electric vehicles connected to the grid improves frequency stability and reduces deviations from nominal value. The vehicle batteries were found to actively respond to load changes, either supplying energy to the grid or absorbing it depending on the situation. The study confirms that V2G technology can effectively participate in frequency regulation services and contribute to maintaining overall power grid stability. |
