Power factor correction and load demand peak shaving in residential town using electric vehicles fleet in smart parking

Abstract

This paper presents an algorithm for compensating the active and reactive power simultaneously in a real residential distribution household system using the amount of energy saved in plug-in hybrid electric vehicles (PHEVs) or in electric vehicles (EVs) parked in smart parking. The system and vehicle's specifications are discussed in separate sections. Moreover, the effects of the algorithm on active power peak shaving, reactive power compensation, and power factor correction are discussed as well. The economic effect of the algorithm on consumers' energy payment bills in Iran's distribution market is depicted in Section 6. Reactive power compensation leads into correction of power factor and power loss reduction. The main reason for connecting vehicles to grid is to charge them in their departure time to the desired state of charge (SOC). This algorithm guarantees that all vehicles will reach their desired state of charge at least half-hour before departure. Finally, the positive effect of the algorithm on all items is demonstrated.
