- Uninterrupted and economic power is very important for a smart power distribution system's operation. A strong transmission and distribution system is needed to supply uninterrupted power, which is challenging and costly for power system operators in the perspective of ever-increasing energy demand. While the number of electric vehicles (EVs) is increasing in the society, by appropriate power management of their batteries, they have the potential to support the uninterruptable power goal. This research analyses different penetration level of electric vehicles in power distribution systems to provide stable energy for the smart devices and observes its impacts on operational costs and environmental emissions. The supply of EV power is determined based on smart device consumption by optimal energy management of EV batteries in such a way that both the utilities and the car owner get benefits. Utilities can save energy by reducing system loss, while EV owners can earn money by selling it to utilities at their convenient time for smart devises operations. The owners of the EVs are responsible for the car charging cost, normally during off-peak hours, and selling it to the grid during peak hours with higher prices. Alternately, in case of extra energy from the EV batteries, it could be used during peak hours to reduce fossil fuel-based energy generation that ultimately helps to reduce electricity generation cost and environmental emissions. The PG&E 69-bus distribution system is used for the simulation and case studies. Case studies in this research show how the power management of EVs batteries charging and discharging characteristics benefits both utilities and EV owners. The uncertainty of the driving pattern of EVs is also considered in the research to get more accurate results.
