The normal operative conditions of a distribution network can be severely affected when a large number of plug-in electric vehicles (PEV) will be connected in an uncontrolled manner. Besides network energy consumption, these PEV can supply part of the energy stored in their batteries. To dispatch the PEV requirements in an economical and controlled form, it is fundamental to develop algorithms, calculation tools and integrated systems that facilitate this functionality. Such systems should interact between electric vehicles and distribution network operators (DNOs). An alternative is to use the concept of ?aggregators?. In this sense, this paper proposes a methodology to solve the short-term economic dispatch (ED) problem of a smart distribution grid (SDG). This ED especially considers the active role that the PEV should play, their representation by aggregators and a hierarchical architecture of economic control required by this purpose.
