Economic dispatch of smart distribution grids considering aggregators of plug-in electric vehicles

摘要

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