Vehicle to grid (V2G) technology has been developed to utilize the electrical energy stored in an idle electric vehicle battery or any other energy storage device. It can assist with increased energy demands during peak load hours, maintain grid stability, avoid the need for peak power plants, etc. Further, it can help increase the indirect penetration of renewable energy sources when used for charging electric vehicle batteries. V2G can be defined as the transfer of power or energy from an electric vehicle battery to the grid using suitable power electronic converters for the purpose of managing load demand. Energy or power transfer using the V2G technique can be divided into four sections, as shown in Figure 6.8.

V2G technology is the technology that allows a grid-able EV to be used as a grid asset. V2G allows bidirectional flow of electrical energy between the vehicle and the grid such that the EV can decide power system dynamics. Information technology has an active role. PHEVs are well suited to act as a grid resource due to their operational flexibility and embedded communications and actuation technology. PHEVs are operationally flexible as they can act as a load (when its battery is charging from the grid) as well as a generating unit (when the battery can deliver power to the grid). Digital and control technologies involved with vehicle safety, navigation, etc. improve the information-sharing capability of the vehicle and make it easier to schedule vehicle charging accordingly [32,33]. The various components of a typical V2G setup are as shown in Figure 3.7. Some other terminologies related with V2G are listed in Table 3.6.

On the plus side, EVs can prove to be quite useful to the power systems in a number of ways: Smart grid: In the smart grid system, intelligent communication and decision-making are incorporated with the grid architecture. Smart grid is highly regarded as the future of power grids and offers a vast array of advantages to maintain reliable power supply and advanced control. In such a system, the much coveted coordinated charging is easily achievable as interaction with the grid system becomes very much convenient even from the user end. The interaction of EVs and smart grid can facilitate opportunities like V2G and better integration of renewable energy. In fact, EV is one the eight priorities listed to create an efficient smart grid [117].V2G: V2G or vehicle to grid is a method where the EV can provide power to the grid. In this system, the vehicles act as loads when they are drawing energy and then can become dynamic energy storages by feeding back the energy to the grid. In coordinated charging, the EV loads are applied in the valley points of the load curve, in V2G; EVs can act as power sources to provide during peak hours.

The recent advancement in smart grid mechanism with the increasing number of plug-in electric vehicles has led to the development of vehicle-to-grid technology. Indeed, this technology enables the smart grid to utilize the unused power from electric vehicles (EVs) which is commonly known as “V2G”. In other words, the stored energy in EVs can be used to power a house when solar PV power is not available at night or during the utility power outage. In this sense, V2G can also inject energy into the power grid particularly during peak hours when EVs are parked. Here, the owner of EV can sell the stored energy which has been accumulated from the excess power generated by solar PV while his vehicle is parked and thus, generating enough income to pay for fast charging at the power charging stations. Although V2G can provide a spinning reserve to the power grid as an autonomous source (Zhu et al. 2013) or as an aggregated source (by incorporating EVs) (Ansari et al. 2015), the challenging problem is the integration of V2G in the current structure of traditional power grid.

Motivated by the above envisagements, the game-changing technology: Vehicle-to-Grid (V2G) brings a new opportunity that helps balance the overload of the power grid and potentially making EV owners money. V2G is the technology that enables bidirectional charging, where EVs can both charge from and discharge into the grid–at present, leading V2G industry players to contain Ensto, AC Propulsion, Coritech Services (Ensto 2019). With V2G, EVs can play the same role as static batteries in managing local loads and participating in energy market value streams. Recent reports and studies have shown the distinctive advantages of V2G on the economy and environment. A previous V2G pilot indicated that EVs could earn around €69 a month using the batteries to help balance supply and demand of power grid (Deign 2018). Another investigation in the UK showed that a 4 kWh electric battery could provide a third of the energy needs for a typical home in the UK (Eric Schmidt 2017). The energy can save from the grid by using EVs when people are at work and running errands to power other buildings as a part of the new grid infrastructure.

From the perspective of the EV owners, EVs provide less operating cost because of their superior efficiency [172], it can be up to 70% where ICE vehicles have efficiencies in the range of 60–70%. The current high cost of EVs is likely to come down from mass production and better energy policies which will further increase the economic gains of the owners. V2G also allows the owners to obtain a financial benefit from their vehicles by providing service to the grid. The power service providers benefit from EV integration mainly by implementing coordinated charging and V2G. It allows them to adopt better peak shaving strategies as well as to integrate renewable sources. EV fleets can lead to $200–$300 savings in cost per vehicle per year.
