“…The use of EVs could increase electricity demand and risk grid damage. This has to be placed in the context of larger national energy strategies as noted in several islands such as Barbados and Malta (Chae et al, 2020; Clairand et al, 2020; Neofytou et al, 2019). If a goal is to reduce GHG emissions and imported fuel costs, renewable energy generation must be implemented (Pina et al, 2014).…”

Small Island States present features, such as compact road networks, low commuter distances, and often large tourism service sectors, that could make the adoption of electric vehicles for transportation which is an attractive way to reduce their costly dependence on imported fossil fuel and their greenhouse gas emissions. Through the transition theory lens, we review the national policy measures and broad clean transportation targets that small island countries are implementing to encourage electric mobility deployment. From information compiled for 18 small island countries, we find a growing trend in electric vehicle and infrastructure development incentives among broader clean transportation transformation policies and nationally determined contribution targets; and large country‐to‐country variations in enabling conditions to smoothen EV transition. Small island countries are not uniform but instead are very dispersed across the transition S‐curve. The review, therefore, finds that the mobility transition requires island‐specific approaches and solutions that will accentuate critical policy and management elements for fostering transitions.

“…The results show the possibility to reduce the emissions and the investments in peak load plants. In [6], a bi-directional scheduling algorithm is developed as distributed frequency regulation source and shows the great opportunity for Vehicleto-Grid (V2G) to take part as frequency regulator. Using bi-directional charging, it is also possible to facilitate the integration of renewable energy sources (RES), as shown in [7].…”

The increasing penetration rate of electric vehicles, associated with a growing charging demand, could induce a negative impact on the electric grid, such as higher peak power demand. To support the electric grid, and to anticipate those peaks, a growing interest exists for forecasting the day-ahead charging demand of electric vehicles. This paper proposes the enhancement of a state-of-the-art deep neural network to forecast the day-ahead charging demand of electric vehicles with a time resolution of 15 min. In particular, new features have been added on the neural network in order to improve the forecasting. The forecaster is applied on an important use case of a local charging site of a hospital. The results show that the mean-absolute error (MAE) and root-mean-square error (RMSE) are respectively reduced by 28.8% and 19.22% thanks to the use of calendar and weather features. The main achievement of this research is the possibility to forecast a high stochastic aggregated EV charging demand on a day-ahead horizon with a MAE lower than 1 kW.

“…EVs are used in power systems to achieve frequency regulation due to their fast-regulating qualities. Adaptive loop control is used to create EVs with primary frequency regulation [5,6]. The frequency response in an islanded system is studied using EVs, and this article looks at frequency regulation in PFC and SFC with and without EVs [7,8].…”

Nowadays Electrical power generation using renewable energy systems brings more novel ideas to satisfy the power demand worldwide. Microgrid is one of the ideas that ensures stability and reliability of the power system. Due to seasonal or climatic effect, the power generated by the renewable energy sources has issue in providing a constant power output and hence produces the power imbalance between the source to load. Furthermore, the system frequency cannot be kept constant in all cases. In this case, an electric vehicle (EV) can serve as a power generation source to support the power grid and meet the Load Frequency Control requirement (LFC). Due to their fast-regulating characteristics, electric vehicles provide frequency regulation services. Electric vehicles are used in both primary and secondary frequency management in power systems to quickly suppress frequency oscillations caused by changes in load. The control centre gathers and updates real-time Electric Vehicle data, such as information regarding state of charge and the state of each Electric Vehicle, in order to decide on load frequency regulation dispatch to Electric Vehicles. This paper compares and consolidate the performance of Load frequency control through Conventional plants and Renewable energy systems. The graphical abstract of power system grid is shown in Figure.1
