Abstract: Power systems can make use of electric vehicle (EV) charging to improve system reliability. EV charging can serve the grid with charging interruption and vehicle-to-grid (V2G) capacity - injecting energy back into the system during the outage. However, the contribution of EVs is uncertain because they serve both the power system and the transportation sector. Scheduled EV charging can be affected either by failures of components such as charging facilities, or by human errors such as punctuality, rounding of time and errors in forecast of energy consumption. Moreover, with the introduction of the aggregator, the realization of EVs' grid services also plays an important role. This paper examines uncertainties of EV charging that can affect the EVs' capability to improve the system reliability. Methods are proposed to incorporate these uncertainties into generating system well-being analysis. Results show that the uncertainties identified directly affect EVs' contribution in the system well-being enhancement.
