New project: Southcoast Microgrid Reliability Feasibility (SµRF)

The Battery Storage and Grid Integration Program at the Australian National University, along with project partners Southcoast Health and Sustainability Alliance, network operator Essential Energy, and technology company Zepben, are delighted by news of successful project funding under the Regional and Remote Communities Reliability Fund (RRCRF) – microgrids 2020-21. 

The Southcoast Microgrid Reliability Feasibility (SµRF) project will engage NSW South Coast Eurobodalla residents, businesses, and Essential Energy in planning the transition from a bushfire exposed grid to a resilient grid of islandable microgrids.  

The project partners will receive $3.125M in funding over three years under the RRCRF to: 

  • conduct community-led design of future energy systems, quantifying the value of reliability;  
  • model the operation of eight microgrids across the region using high-resolution monitoring data and develop a holistic assessment of implementation costs; and 
  • explore business models and regulatory innovations to improve feasibility implementation.

Obey your master … how algorithms can steer a neighbourhood battery

Ecogeneration interview about our Nature Energy paper on battery algorithms

Research shows that if energy professionals and customers agree on what they expect a community battery to do, engineers can write performance algorithms to suit those objectives.

Can you trust a battery to make the best decisions about when to charge and discharge? It depends who owns it, for a start, but most of all it depends who wrote the code that is its book of commands.

As community batteries are deployed to manage solar exports and calm grid disturbances, researchers at the Australian National University wanted to understand the degree to which these assets can be bent to serve their owners or the communities they are plonked in the middle of.

“How an electric vehicle or a battery operates in your home, these things are governed by algorithms coded up by humans,” says ANU battery storage and grid integration research leader Bjorn Sturmberg. “They are not governed by the physics of spinning machines, which is traditionally what we have built our energy system around.”

Stories from the opening of the DERlab

More renewable technology will be able to be integrated into Australia’s energy grid, thanks to a new state-of-the-art laboratory in Canberra.

The Australian National University’s Distributed Energy Resources Lab, which was opened on Tuesday, will allow for researchers, energy companies and start-ups in the industry to test their technology in real-world settings before they become built in to the broader energy grid.

The laboratory has been a project more than two years in the making, with more than $1.5 million in funding provided by the ACT government.

Applying responsible algorithm design to neighbourhood-scale batteries in Australia

Our new paper in Nature Energy asks fundamental questions of what values and biases algorithms are encoding into our digital energy system.

Abstract below:
The digital energy era presents at least three systemic concerns to the design and operation of algorithms: bias of considerations towards the easily quantifiable; inhibition of explainability; and undermining of trust and inclusion, as well as energy users’ autonomy and control. Here we examine these tensions through an interdisciplinary study that reveals the diversity of possible algorithms and their accompanying material effects, focused on neighbourhood-scale batteries (NSBs) in Australia. We conducted qualitative research with energy sector professionals and citizens to understand the range of perceived benefits and risks of NSBs and the algorithms that drive their behaviour. Issues raised by stakeholders were integrated into NSB optimization algorithms whose effects on NSB owners and customers were quantified through techno-economic modelling. Our results show the allocation of benefits and risks vary considerably between different algorithm designs. This indicates a need to improve energy algorithm governance, enabling accountability and responsiveness across the design and use of algorithms so that the digitization of energy technology does not lead to adverse public outcomes.

DERlab launch

After more than two years of research, design and construction our DERlab is ready for public launch!

The launch on the 13th of July will feature the Chief Minister of the ACT, Andrew Barr, and Vice-Chancellor of the ANU, Brian Schmidt.

Check your mirrors: 3 things rooftop solar can teach us about Australia’s electric car rollout

“The electric vehicle transition is about more than just doing away with vehicles powered by fossil fuels. We must also ensure quality technology and infrastructure, anticipate the future and avoid unwanted outcomes, such as entrenching disadvantage.

Australia’s world-leading rollout of rooftop solar power systems offers a guide to help navigate the transition. We’ve identified three key lessons on what’s gone well, and in hindsight, what could have been done differently.”

Microgrids: how to keep the power on when disaster hits

It’s timely to consider how we can build a better system – one that’s more resilient in times of disaster and also doesn’t contribute, through carbon emissions, to making disasters more frequent.

One part of the solution is more connectedness, so one transmission line being severed is not the crisis it is now.

But just as important is ensuring connectedness isn’t crucial.

This means moving away from centralised systems – powered by a few big generators – to decentralised ones, with many local and small-scale generators. Instead of one big grid, we need many microgrids, interconnected but able to operate independently when necessary.

Get in on the ground floor: how apartments can join the solar boom

While there are now more solar panels in Australia than people, the many Australians who live in apartments have largely been locked out of this solar revolution by a minefield of red tape and potentially uninformed strata committees.

In the face of these challenges, Stucco, a small co-operative housing block in Sydney, embarked on a mission to take back the power. Hopefully their experiences can serve as a guide to how other apartment-dwellers can more readily go solar.

Owners of electric vehicles to be paid to plug into the grid to help avoid blackouts

Electric vehicles can help keep the air clean in our cities – as we’ve seen recently with the reduction of traffic through COVID-19 lockdowns – but they face two obstacles.

In the short term they’re still expensive. In the long term charging millions of vehicles from the electricity grid presents challenges.

I’m part of a new project, launched today, that tackles both of these obstacles head-on, and it could mean owners earn more money than they’re likely to pay for charging their electric vehicles.
