The Electric Nation V2G project will implement an EV bi-directional V2G charging platform to test the effects on low voltage networks for future use of this technology by electric vehicle users. The project will establish a network of between 90-110 V2G chargers within domestic properties. The chargers will be divided into 3 to 5 groups of circa. 25 units each; these groups will be offered to partner energy suppliers and aggregators who are offering or developing advanced energy services that can utilise battery storage. By utilising the Crowd Charge platform these partners will be able to easily and quickly experiment with charging and discharging the vehicle batteries to suit their energy trading requirements. The data gathered from the chargers will give a unique insight into possible future demands on the low voltage network driven by energy trading and grid services. Furthermore, the Crowd Charge platform will be used to control charging across the whole network, as an additional supervisory control layer, to keep within DSO specified current limits to simulate a constrained node in the LV network (feeder or substation). It is envisaged that an element of the properties may also have solar generation attached and study of the whole home demand will be included as part of the trial.
The aims of the project are as follows:
  1. Explore and report on the impact of V2G charging on the LV network utilising end-user trial charging data and analysis.
  2. Demonstrate, via modelling, to what extent V2G can assist with management of LV network demand.
  3. Examine how sophisticated dynamic bi-directional energy services based on vehicle battery storage, from a variety of energy suppliers, may impact the LV infrastructure. 
  4. Provide recommendations for policy and commercial frameworks on V2G services.
The outcomes of the project and the resulting benefits are: 
  1. Review the grid connection process and assess if this is fit for purpose, considering the increased V2G charging up-take within the next 2-5 years, and provide efficiency recommendations to WPD and the installers.
  2. Examine how sophisticated dynamic bi-directional energy services based on vehicle battery storage, from a variety of energy suppliers, is valuable for DNOs to anticipate and understand the energy suppliers customer proposition, so they can react accordingly and work concurrently with the suppliers as the services develop in BAU operation.
  3. Demonstrate, via modelling, to what extent V2G charging can assist WPD with the management of the LV network in various network scenarios, specifically, by simultaneous management of the energy suppliers trading within the networks’ safe operational limits, thus allowing DNOs to understand and plan for a future world in which V2G charging is commonplace.
