The large scale electrification of the transport sector will result in increasingly peaky loads which necessitates the system integration of additional capital intensive storage infrastructure in renewables rich microgrids of the future In this context the vehicle to grid V2G technology can provide an effective platform to unlock the so called storage on wheels potential of electric vehicles EVs thereby reducing the need for cost prohibitive grid scale storage However the dispatch optimization of electricity networks integrating a high share of V2G enabled EVs is challenging given the uncertainties in forecasts of the associated timing of charging and discharging In response this paper introduces a novel mixed integer linear programming based model for the optimal operation of a grid connected microgrid MG integrating solar photovoltaic and wind turbine generation systems which are supported by a hydrogen based energy storage system whilst assuming a high level of EV penetration To this end the information gap decision theory IGDT is employed to evaluate the impact of risk averse RA and risk seeking RS strategies against the possible aggregated EV charging discharging scenarios where limited information is available about relevant driving patterns Importantly the simulation results from a test case community MG system indicate that the RA and RS strategies are associated with a representative daily MG operation profit deviation of 21 and 19 compared to the most likely risk neutral strategy respectively
