Modeling and Simulation of Vehicle to Grid (V2G) Integration

A Vehicle-to-Grid (V2G) integrated microgrid system, which represents a potential community-scale energy network, is modelled and simulated in this article. A diesel generator for base power generation, renewable energy sources (wind farms and photovoltaic cells), residential loads, and a V2G system with 100 electric cars make up the simulated microgrid. By controlling car battery charging and discharging, the V2G system provides grid support on a day of low demand for around 1,000 homes. While the PV farm and wind farm offer renewable energy based on real-time solar irradiance and wind profiles, the diesel generator maintains power balance by making up for variations in generation and consumption. Electric car charging and grid stability during power outages are the two functions of the V2G technology. Realistic charging patterns and energy availability are reflected in the modelling of five different vehicle-user profiles. Dynamic events like asynchronous machine starting, partial solar shading, and wind farm disconnection are all included in the 24-hour simulation. The system’s reaction to these occurrences is examined in the article, with particular attention paid to grid frequency stability, renewable power variability, and V2G’s function in load balancing and frequency control. The findings demonstrate how V2G integration may improve grid stability and lessen the erratic nature of renewable energy sources in energy systems of the future.
