A team from The Australian National University (ANU) will lead research into how electric vehicles (EVs) can support our energy grids.

The EVs will act to prevent blackouts and the researchers say that if all of Australia’s vehicles went electric they would provide more power than five Snowy Hydro 2.0s.

The Australian-first trial will show how EVs can contribute to energy security by injecting power into the grid.  

The two-year Realising Electric Vehicles-to-grid Services (REVS) project, recently announced by ARENA, aims to demonstrate the feasibility of vehicle-to-grid (V2G) services.

Fifty ACT Government Nissan LEAF EVs and one ActewAGL Nissan LEAF EV will take part in this ground-breaking study that will allow EV batteries to provide power into the grid, almost instantaneously when needed, to avoid blackouts. 

The ANU team is working to unlock the wider potential of V2G services by researching their social, technical and economic aspects. This transdisciplinary approach addresses the shortcomings of previous trials.

Research lead Dr Bjorn Sturmberg from the Battery Storage and Grid Integration Program at ANU believes the project has the potential to enable a more resilient energy system with higher levels of renewable energy, like rooftop solar.

“We know V2G works in the lab but we need to demonstrate the reliability and viability of V2G services in the real world at scale,” Dr Sturmberg said.

“We need to prove the control, coordination, and cybersecurity of the technology systems, as well as the crucial business and regulatory models to make V2G attractive to all stakeholders. 

“As a stepping stone to the field deployment the project will leverage the state-of-the-art grid simulation facility at the ANU – the Distributed Energy Resources (DER) Lab. This will allow the charger to be rapidly prototyped to respond to the frequency disturbances that occur when the grid is on the brink of a blackout.”

According to Dr Sturmberg, the ultra-fast reactions of EV batteries make them extremely adept at balancing the grid.

“One EV battery typically contains as much energy as an average household uses over two-to-four days and can react to events in a tenth of a second,” he said. 

“If all of Australia’s 19 million vehicles were electric, they would store more energy than five Snowy 2.0s, or over 10,000 Tesla Big Batteries.”

It’s hoped the research will help transform EV charging from a challenge for the grid into an asset that boosts energy reliability and security.  

The REVS project is supported by $2.4 million funding by the Australian Renewable Energy Agency (ARENA), as part of ARENA’s Advancing Renewables Program. The REVS consortium covers the whole electricity and transport supply chains including ActewAGL, Evoenergy, Nissan, Sgfleet, JET Charge, ACT Government and The Australian National University. 

The Battery Storage and Grid Integration Program, hosted at ANU, is jointly funded by the ACT Government under the Renewable Energy Innovation Fund initiative and the ANU. Established in April 2018, as an initiative of the ANU Energy Change Institute, the Battery Storage and Grid Integration Program consists of a collaborative community that researches solutions to real-world energy and associated systems problems in a holistic manner.
