Management of Energy in Smart Distribution Network Response to operation peformance of Plug-in Hybrid Electric Vehicles

Charging performance of Plug-in Hybrid electric vehicles (PHEVs) under variant charging approaches brings new challenges for distribution grid such as feederoverloading, and increment of loss. In this paper, the impact of charging PHEVs on the load profile are evaluated considering Demand Response (DR) programsin order to minimize the impact of charging PHEVs on load profile. In the proposed DR strategy, all consumers can determine and control their loads. Also,the proposed DR strategy can satisfy the function of reducing peak with regard to different PHEV penetration while preserving consumer comfort levels. Forperforming DR programs, a time of use and real time pricing model are used to evaluate the impacts of charging of PHEVs on distribution system operations considering a 33-node test feeder with 11.3%, 35%, and 45% PHEV penetrations in residential loads. Furthermore, Uncertainties associated with PHEV charging performances are handled with Monte Carlo simulation. Results validate that the amount of peak loss, and peak to average ratio (PAR) increase owing to PHEVs penetration growth. Also, the results illustrate that scheduling for the operation of PHEVs with DR program reduces the distribution losses, and PAR.
