A new approach to apply aggregators for PHEVs in a smart city

The novelty of this paper is in applying aggregators in a smart city with thousands of EVs with ability to have “V2G” feature. Aggregators are considered as a third party side that will ease lots of relations between operators and consumers. In this paper we will use some protocols in applying aggregators and will simulate PHEVs by using this method. Simulation of these vehicles in smart parking lots has been done using Security Constrained Unit Commitment (SCUC) in GAMS software. Results are drawn to study different systems performances, such as: social welfare, generation costs, amount of not supplied load, and lines loading have been investigated. The simulation studies are carried out for two cases with including line limit and without lines limits. The simulation results show that proper utilization of PHEVs has potential for increasing social welfare and decreasing not supplied load.
