This work aims to investigate the impact of electric vehicles (EVs) charging/discharging strategies on the optimal operation of islanded microgrid (MG). For this purpose, firstly, load model of EVs under four different charging/discharging strategies, namely, uncoordinated charging mode, maximum renewable mode, valley filling mode and charging discharging mode is established. Thereafter, impact of these strategies on the optimal operation of MG is investigated. A 2 m point estimate method is used to study the impact of forecast errors associated with load demand and renewable energy sources on the MG total cost under different EV charging/discharging strategies. Finally, a sensitivity analysis of variations of battery parameters on the MG total cost is also presented.
