Overview of plug-in electric vehicles as providers of ancillary services

Proliferation of plug-in electric vehicles obviously involves an interesting potential of electric energy storage for purposes related to smart grids. Among other opportunities, the possibility of providing ancillary services to the distribution grids they are connected to is evaluated in this paper as an added advantage of this kind of vehicles. Issues like aggregation needs, incentives, coordination with the aggregation manager and generation of setpoints, as well as the charging/discharging constraints of PEV batteries depending on the task to be performed are addressed, as an overview of the most recent literature related to the subject.
