15.1 Introduction

Electric vehicles constitute an important asset for the smart grid. In this new context, their functions are not just limited to the users' transportation, but they can also participate in the smart grid operations actively (Shareef et al., 2016). The expected inclusion of a relevant number of EVs in the near future will alter the power network performance in such a way that they will affect the load flattening, on the fast frequency control and on easing the integration of renewable energy sources.

Its influence depends on the number of EVs, the time their charges are scheduled, and their ability to deliver energy to the grid acting as mobile network storage systems. This last function is considered in the V2G (vehicle‐to‐grid) scenarios where the power transfer is also feasible from the vehicle to the grid. In this sense, the vehicles operate as sources when they are parked and the V2G function is enabled. The EV owners obtain some economical revenues for their participation in this kind of service (Shareef et al., 2016) while the power network also gets important benefits. The V2G procedures, when done in a coordinated way, are expected to improve power network performance and its reliability. As summarized ...
