“State-owned distributor Horizon Power says a trial using bi-directional
charging with electric vehicles to supplement the grid and take up excess power
has proved a success.
The 12-month trial was conducted in Exmouth, a town of nearly 3,000 people in
Western Australia's north-west, and involved testing Horizon's Distributed
Energy Resource Management System (DERMS) in real-world conditions.
It makes use of a vehicle's large battery to both power the car and power the
supply grid when parked, known as vehicle-to-grid services, or V2G.
Ray Achemedei, executive general of manager technology and digital
transformation at Horizon Power, explained the trial to Nadia Mitsopoulos on
ABC Radio Perth.
"Basically what we did is we got a fleet of Nissan Leafs and we allocated those
Leafs to some partners up at Exmouth," Mr Achemedei said.
"The agreement was that they would get to use these Leafs day in, day out and
help participate in some trials along the way.
"We used our DERMS platform to issue instructions to the EVs and send signals
to the batteries on those EVs to either discharge energy [to the grid] or to
charge the battery itself at different times under different conditions to see
how that went.
"The real objective was to see if the batteries could deliver an outcome that
would be to the benefit of the customer, as well as to us, the utility
provider, and do it in a way that didn't disrupt the customer's experience."
The DERMS platform was able to draw power from the EVs' batteries at times of
high demand, and at times of low demand implement fast charging into the cars
to ease stress on the system.
Settings were in place to ensure the batteries were never entirely drained,
leaving the user still able to jump in the car if they needed to go somewhere.”
