Lead researcher at Deakin's Better Consumption Lab, Associate Professor Josh Newton, set the context for the project: 'From the perspective of achieving net-zero emissions, there's a whole range of things that need to happen to help Australia decarbonise its energy sector,” he says. “We need to shift the profile of generating capacity within Australia away from coal-fired power plants, for example, to renewables.'
Associate Professor Newton says another priority is to look at what happens as households and businesses start to adopt batteries and how we incorporate them into the power grid more holistically.
'Once you start to disperse this storage capacity across a huge number of households, there are some potential benefits for being able to increase the resilience of households and the national electricity market,' he says.
'It means that if you have a power outage, households can still maintain their access to electricity, even though the broader grid has fallen over '
Another benefit is the ability to share power with other households.
'Once households sign up to a virtual power plant, the electricity they generate and store can be made available to other nearby households,' says Associate Professor Newton, adding that this can provide grid resilience in the event that the grid is disrupted by storms or bushfires.
Virtual power plants can also help to balance electricity supply and demand.
'Most of these batteries are attached to rooftop solar panels,' he says. 'These batteries can therefore store the power that solar panels generate in the middle of the day, when fewer people need it, and make it available for both the house and the broader community at night or first in the morning, when household demand for electricity is greatest.'
