Incorporating valley filling and peak shaving in a utility function based management of an electric vehicle aggregator

Shifting load away from the system peak into evening hours when the load is low and the network's capacity is high is referred to as peak shaving and valley filling. This paper develops an approach to enforce such a charging behavior to a large fleet of individual electric vehicles. The vehicles move in a transportation network which is mapped to a realistic urban electricity distribution system. Each vehicle features a utility function based on which the charging is controlled. The algorithm tunes the utility function parameters order to initiate the desired charging behavior. Individual behavioral constraints, such as a desired state of charge when leaving, are fully considered.
