Aston University trials Vehicle-to-Grid system

Birmingham’s Aston University was host to a recent demonstration of the capabilities of using EVs to feed the electricity grid.

The VIGIL (VehIcle to Grid Intelligent controL) collaborative project has successfully met its aim of building and trialling an off-vehicle communication and control platform that will encourage building owners and electric vehicle infrastructure owners to adopt V2G (Vehicle to Grid) technology as part of future charging networks.

The VIGIL consortium consists of Aston University, ByteSnap Design, Grid Edge and Nortech Management. The group has successfully demonstrated the capability of VIGIL to regulate EV charging/discharging with building energy dispatch alongside electrical network constraints at two sites on the Aston University campus in Birmingham.

Funded by the Office for Low Emission Vehicles (OLEV) and the Department for Business Energy and Industrial Strategy (BEIS), in partnership with Innovate UK, the VIGIL platform is UK’s first comprehensive communication and control platform for managing energy distribution preventing peak load problems which can risk overloading the energy distribution network.

During the project, the bidirectional power that flows between EVs, buildings and electric networks were monitored and controlled in real-time. Now, the VIGIL platform operates in full control of how, when and the rate at which EVs are charged/discharged with the simultaneous consideration of multiple constraints.

Main project outcomes included:

* Nortech developed the V2G ANM controller that monitors the voltage level and available capacity at local substations to ensure the network operates within regulated limits.
* Grid Edge provided the distributed energy asset optimisation methods and controls for VIGIL.
* ByteSnap Design completed the development of a smart charge point communications controller.

The controller, named RAY, provides interoperability and control of any EV charger via OCPP 2.0 communications standard and can be adapted for controlling many other V2G or smart chargers with different communication standards providing complete local control.
