AEMO is looking at how electric vehicles fit into the grid. Head of consumer analytics Greg Staib even imagines them being used as batteries at peak times, pity if you are trying to flag down a share car at the same time.
This is one of a series of podcasts taken from presentations at the recent Electric Vehicle Transition conference co-hosted by The Drivenand RenewEconomy. To hear more, please click here.
Very nice talk, AEMO has not been ignoring the issue that is for sure.
Their prime focus is to maintain continuity of electricity supply ie as much power as needed whenever it is needed without any loss of quality in voltage or frequency.
My hope is that they will keep people/ consumers top of their priority list. IE AEMO, and the grid exist to serve the public and the public are not their cash

The price of electricity at the charger will most likely be the principle way of adjusting flow or demand for electricity. This is already done with petrol and diesel. Two reasons to charge a BEV 1. Because you need to, no matter what the price, the vehicle needs a charge otherwise you are stuck with a road side ornament. 2. Because the price is right.
Looking at these two motivations, 1. Would be fairly unpredictable but probably occur at peak driving times and at intercity locations. 2. Would occur when most people are stationary either at night at home or in the day at work.
The nighttime charging would take advantage of rooftop solar or cheap overnight tariffs and would only really occur if the home has a battery. Daytime charging would see charging at car parks or the workplace and to a degree at the home. This would be an ideal time for excess solar to be soaked up by the parked car fleet. To encourage this form of charging prices will need to be low.
To provide a service to those on the go but desperate for a charge, prices can be high. This would be at roadside charging stations.
There will be a subset of people who will use their vehicle as an energy transportation device V2H, this may not be all bad and could allow more use of grid electricity in the day when the solar resource is available and less grid use at night when the energy is needed. It could also allow high prices on days when the grid resource is low discouraging charging activity or at the very least appropriately making money when the resource is scarce.
