Integration of electric transport with smart grids

The energy crisis and environmental concerns have pushed the use of electric vehicles (EVs) as a more common alternative to traditional vehicles with internal combustion engines. With the development of the intelligent power grid concept in the electrical system, the contribution of electric cars to vehicle-to-grid (V2G) technology has expanded recently. With the help of technology, electric vehicles and grid infrastructure may interchange energy in both directions. This allows the grid to receive a variety of services, such as load leveling, reactive power adjustment, sharing peak loads, rotating reserves, and grid regulation. The impact of charging several EV batteries at once on the power grid is a big concern as it may dramatically alter the system’s overall demand profile. The problem is that grid operators and electric utilities have no control over how EVs charge because only the consumer can do this. If EV charging is not adequately controlled, the risk of grid overload can result in a decline in grid performance, poor power quality and/or voltage variations, and even a blackout of the entire power system. To improve voltage regulation and droop management, V2G technology enables ramping up and down in response to the load on the system. Time-of-use rates can guide the utilization of EV charging. An improved grid with genuine environmental benefits for all users might be achieved with a smart grid that is well-equipped to handle the additional EV loads and benefit from the intersection of the electric power network and EVs.
