  This paper presents a real time control strategy for energy storage systems
integration in electric vehicles fast charging applications combined with
generation from intermittent renewable energy sources. A two steps approach
taking advantage of the model predictive control methodology is designed on
purpose to optimally allocate the reference charging power while managing the
priority among the plugged vehicles and then control the storage for
efficiently sustaining the charging process. Two different use cases are
considered: in the former the charging area is disconnected from the grid, so
that the objective is to minimize the deviation of electric vehicles charging
power from the nominal value; in the latter the focus is on the point of
connection to the grid and the need of mitigating the related power flow. In
both cases the fundamental requirement for feasible control system operation is
to guarantee stability of the storage's state of charge over the time.
Simulation results are provided and discussed in detail, showing the
effectiveness of the proposed approach.
