Improving energy distribution for EV charging over public lighting systems

Abstract

The success of the charging infrastructure deployed for Electric Vehicles (EV) charging should not only rely on the size of the network, but on the proper management of the resources available. When the charging infrastructure is shared in order to provide different services, the constraints imposed by the System Operator (SO) of the electric network must always be respected to guarantee the simultaneous operation of all the services provided. TeleWatt is an innovative EV charging infrastructure which is shared with the electric network deployed for the Public Lighting System (PLS). The first approach of this solution remained quite conservative, as the main scope was to prove that the PLS and the EV charging system could operate simultaneously. The present work proposes the adaptation of some well-known on-line scheduling policies to the infrastructure of TeleWatt, which is limited by the constraints of the PLS network. This allows to treat the charge of EVs as tasks and manage them according to different priorities. This work demonstrates how the performance of the system could be improved without any physical changes in the infrastructure, but just by the way that the resources are managed.
