“…First, the probability that the charging station will operate normally should be calculated using Equation (16). The values presented in [50] were used. It was assumed that µ EVSE = 20, 000 per 1 million hours and λ EVSE = 11.3266 per 1 million hours [50].…”

“…As can be seen from Equation (12), the probability of V2G service from the EndUs perspective is determined by two separable events-charging station operation (1-P(F EVSE )) and the charging station availability at the service location (P(D PL )). The values to calculate the first one can be found in [50]. The authors in [50] used a two-state model in their calculations.…”

“…The values to calculate the first one can be found in [50]. The authors in [50] used a two-state model in their calculations. It should be noted that the transition intensities from state "0" to "1" and "1" to "0" are unique for each parameter analyzed and will be identified when discussing the individual probabilities.…”

One of the key aspects of vehicle-to-grid technology (V2G) is the analysis of uncertainty in electric vehicle user behavior. Correct estimation of the amount of available energy from electric vehicles that are expected to provide ancillary services to the electricity system operator or to secure the end user’s demand is essential to design these services in an appropriate way. Therefore, it is necessary to analyze the probabilities of V2G service performance for different scenarios. This paper presents the author’s approach to determining the values of V2G service provision probabilities using survey data. It was found that estimating these values using simulation and forecasting tools makes sense when the coefficients resulting from survey responses are used as initial data. Thus, the paper also presents the results of the surveys that were conducted. As the results from the simulations show, the values of the probabilities of V2G services are not high, which should induce future operators of V2G services to offer a beneficial product for the customer.

“…Since fossil fuels are the primary source of energy for the transportation sector, their contribution to the immense air pollution and greenhouse gas emissions has increased environmental concerns. Transportation sector organizations aim to adapt EVs into the up‐to‐date power grids to operate a clean energy viewpoint [2]. With the large‐scale development of the EVs, a significant reduction in the use of petroleum, greenhouse gas emissions, and fossil fuel dependence has been observed [3].…”

Electrical vehicle (EV) technology has gained popularity due to its higher efficiency, less maintenance, and lower dependence on fossil fuels. However, a longer charging time is a significant barrier to its complete adaptation. Solid state transformer (SST) based extreme fast charging schemes have emerged as an appealing idea with an ability to provide a refuelling capability analogous to that of gasoline vehicles. Therefore, this paper reviews the EV charger requirements, specifications, and design criteria for high power applications. At first, the key barriers of using a traditional low frequency transformer (LFT) are discussed, and potential solutions are suggested by replacing the conventional LFT with high frequency SST at extreme fast-charging (XFC) stations. Then, various SST-based converter topologies and their control for EV fast-charging stations are described. The reviewed control strategies are compared while considering several factors such as harmonics, voltage drop under varying loading conditions, dc offset load unbalances, overloads, and protection against system disturbances. Furthermore, the realization of SST for EV charging is comprehensively discussed, which facilitates understanding the current challenges, based on which potential solutions are also suggested.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
