Regional Energy Arbitrage With Electric Vehicles Mobility Using Voltage-Cost Curve

Tremendous electric load growth has been observed over the last decade, and generating resources are increasingly constrained within clean energy policies. Demand flexibility is widely perceived as a plausible alternate solution to address this problem. This study proposes a methodology to exploit regional electricity consumption patterns for cost efficient energy arbitrage between electric vehicle charging and the local utility. It is proposed that the utility will propagate a market mechanism based on Voltage-Cost curve and collective agents (CAs) will act as aggregators on behalf of residents owning electric vehicles to participate in this cost-curve-driven market. A balanced market would serve the interests of both stakeholders, utility and the CAs. The proposed framework is tested with a real campus distribution system and actual load profiles. Cases with and without high PV penetration are simulated. Results verify the practicability of the developed approach by projecting benefits over a year’s time-span. Future directions are also proposed.
