This paper presents a real-time, greedy-index based dispatching policy (GIDP) for dispatching plug-in electric vehicles (PEVs) to maximize the aggregator’s profit by providing frequency regulation services. A new service cost allocation mechanism is proposed to award PEVs by the amount of service they provide, compensation for delayed-charging, and reduction of battery lifetime because of battery degradation. The proposed GIDP transforms a high-dimensional optimization problem into the one-dimensional space while preserving its solution optimality. By solving the transformed problem in real time, the global optimality of the GIDP solution can be guaranteed by the mathematically proved “indexability”. In Part II of this paper, we present case studies for validating its solution optimality and comparing its performance with two other algorithms.
