Executive Summary

The authors evaluate the impact of limitations that may exist in actual implementations of plug-in electrical vehicle chargers (e.g. no controllable charging current) on smart charging algorithms. They use quadratic programming to control and coordinate the charging of multiple vehicles in order to reduce the peak load and load profile variability observed by a distribution grid transformer. Simulation results are presented for a section of a residential distribution grid comprising 150 households. Charging these electrical vehicles will significantly impact the daily load profile of the power grid: adding a single PEV to a residential home approximately doubles that household's average total power consumption.
