Demand Charge Management Based on Battery Aggregation of Commercial and Passenger Electric Fleet Vehicles

This paper proposes a load management platform to help industrial and commercial electricity customers assess the feasibility of demand charge management through battery aggregation of commercial and passenger Electric Vehicles (EVs). While electric fleet vehicles primarily serve logistical purposes, they can also contribute to energy services as long as these additional functions do not compromise their primary role. In this paper, as a part of the operation planning model, a new time-indexed vehicle routing formulation compatible with energy management equations is developed to allow fleet owners to simultaneously schedule their logistics and energy management systems. The operation planning model also considers the passenger EVs owned by a load entity and its staff and prepares them for energy services by handling their charge and discharge. Two illustrative case studies are employed to demonstrate the advantage of the proposed operation planning model over an available baseline. Additionally, for larger benchmarks, Column Generation and Branch-and-Price techniques is employed to decompose the large instances into smaller, more manageable problems for efficient solving.
