New battery sizing approach for virtual synchronous generators, control-based grid-forming inverters
A group of researchers has outlined a new methodology to determine the minimum power rating of energy storage systems (ESSs) used for emergency under-frequency response. The ESS size must be calculated to maintain the frequency within the standard operating range.
Buildings can offer gigawatts of new peak capacity as ‘batteries’
Modeling shows that shifting just one-third of the electricity consumption of commercial and institutional buildings in Australia to the middle of the day, coinciding with peak solar supply, would create almost 12 GW of new peak capacity in the National Electricity Market.
Nextracker to use local steel in 480 MW Queensland project
In the Australian leg of its global strategy, US-based tracker supplier Nextracker will use locally produced steel for a major project.
Printed flexible solar cells for space applications
Printed flexible solar cell technology developed by Australia’s national science agency has been successfully launched into space as part of billionaire Elon Musk’s Space X’s Transporter-10 mission.
U.S. draft rules may disqualify Australian critical minerals from IRA subsidies
A number of critical mineral producers will likely be ineligible for U.S. Inflation Reduction Act (IRA) subsidies, as the US government has published draft rules forbidding access to enterprises with stakes held by Chinese investors.
Fortescue continues U.S. expansion with new clean energy manufacturing plant
Australian mining and green energy major Fortescue has revealed plans to establish a new clean energy technology manufacturing plant in the United States, as it looks to take advantage of the US Inflation Reduction Act (IRA).
Mitigating residential duck curve via solar pre-cooling
Solar pre-cooling consists of using residential PV systems to run air conditioners to pre-cool residential and commercial buildings. It offers benefits in terms of mitigating low minimum demand in electricity networks, flattening the grid’s net demand profile, and reducing electricity bills.
U.S. Inflation Reduction Act poses threat for Australia in green hydrogen race
Former Reserve Bank of Australia Deputy Governor Guy Debelle has warned that the U.S. Inflation Reduction Act (IRA) poses a “material threat” to Australia’s push to become a green hydrogen superpower.
Renewables generation predictability can improve profitability
A study from the University of Adelaide shows how improved predictability can improve the operation of solar assets.
Array Technologies expands solar tracker manufacturing to Australia
U.S. solar tracker supplier Array Technologies plans to set up a factory in Australia, after winning a contract to supply trackers for a 102 MW solar farm in the Australian state of Victoria.
