An Event-Driven Dual Coordination Mechanism for Demand Side Management of PHEVs

This paper addresses the challenges of integrating existing PHEV charging algorithms, which optimize PHEV charging per market timeslot (e.g., 15 minutes), into an environment with realistic communication conditions. To address this challenge, we propose a dual coordination mechanism, which controls a cluster of devices on two different operation levels: market operation and real-time operation. The market operation level uses an existing timeslot-based algorithm to calculate a charging schedule per timeslot. The real-time operation level translates this schedule into event-based control actions for a realistic communication environment, wherein a limited number of messages can be exchanged. A case study of 1000 PHEVs shows that it is possible to achieve results on par with the timeslot based algorithm but with significantly reduced communication with the PHEVs.
