Modeling Disaggregated Electric Vehicles Availability on a Low-Voltage Distribution Network

The possible use of electric vehicles as flexible resources for the electricity system depends on the understanding of their spatial and temporal availability. We contribute to state-of-the-art research with a model of mobility that is able to estimate the availability of vehicles on a residential distribution network in a disaggregated fashion over the course of a week. The model can be used to study distributed and user-oriented control approaches, as opposed to typical vehicle-to-grid approaches, which require vehicle fleets aggregators for the provision of ancillary services. An application of the model is presented with a case study, where the effect of a simple vehicle to-building control strategy, aiming to maximize self consumption of photovoltaic energy, is analyzed. It appears clear that electro-mobility offers a great potential for the integration of high share of solar energy in low-voltage networks even in case of control approaches that tend to maximize only the user's interest.
