A Market Mechanism for Electric Vehicle Charging under Network Constraints

Abstract

The increasing impact of electric vehicles on distribution networks can be alleviated by smart charging-the shifting of electric vehicle load to times when there is available capacity in the network. This work presents a market mechanism for smart charging that optimally allocates available charging capacity in a way that ensures network stability, while at the same time allowing vehicles to express individual preferences regarding their charging rates. Those who want higher rates can receive these, but must pay a higher price. The mechanism takes into account network-specific constraints such as total network load, voltage drop, and phase unbalance. However, since vehicles have differing im..
