How can electric vehicles support grid stability in smart cities?

Electric vehicles can support grid stability in smart cities by acting as energy storage units. This concept is often referred to as vehicle-to-grid (V2G) technology, where electric vehicles can store energy when demand is low and supply it back to the grid when there is a high demand for electricity.

When many electric vehicles are connected to the grid, they can collectively provide a significant amount of energy storage capacity. This helps balance supply and demand on the grid, especially during peak usage times. During periods of high renewable energy production, such as sunny or windy days, electric vehicles can charge from the surplus energy, effectively storing it. Conversely, when demand exceeds supply, these vehicles can discharge the stored energy back to the grid, thus supporting stability and reliability.

Moreover, this capability not only supports the grid but can also provide financial incentives to electric vehicle owners, who can benefit from selling their stored energy back to utilities. The integration of electric vehicles into the smartgrid ecosystem enhances overall energy efficiency and promotes the use of renewable energy sources, further contributing to environmental sustainability.
