Wireless communication based phase balancing to integrate PHEVs in a smart parking lot

摘要

With an expected increase in adoption of electric vehicles and widespread deployment of smart grids, a variety of opportunities are opening up for the use of electric vehicles as a new renewable resource storing excess power in light load situation or supporting grid during peak load. This can be made practical if a large number of such vehicles are concentrated in one place, like the parking lot of a large organization. One predicted problem in such a scenario is the phase imbalance caused by arbitrary spread of vehicles over the three phases, which can lead to distribution circuit trips. This paper proposes a phase balancing mechanism, implemented with the help of wireless communication between electric vehicles and a master controller implementing the phase balancing, in a smart grid environment.
