On-line scheduling policies for Electric Vehicle charging over public lighting systems

Abstract

Elevated installation costs of the Electric Vehicle Supply Equipments (EVSE) could limit the deployment of charging stations for Electric Vehicles (EVs). In our previous work, we presented a new alternative to expand the network of charging points at a low cost. In the proposed model, the installation costs are reduced by deploying the charging infrastructure over the Public Lighting System (PLS) electric network, which is already deployed. The feasibility of this approach was proven via simulation. The first approach of the model considers a conservative charging strategy. This strategy simulates the arrival of a vehicle in advance in order to assure that when a new connection occurs, the network constraints will still be respected. Therefore, the new vehicles can start charging just after their connection without any problems. However, this approach could limit the performance of the system. The purpose of this work is to study the performance of the charging infrastructure over the PLS when some of the most well known on-line scheduling strategies are implemented. These strategies are characterized by their flexibility for treating the charging processes while respecting the constraints of a low voltage network.
