Energy Management Systems

Batteries in South Australia have been paid to charge throughout September and October 2021 due to a record number of negative price intervals. Wholesale electricity prices were negative almost 40% of the time.

The Paris-based body expects the world will have installed almost 160 GW of solar this year, a record number, but still not enough to keep the prospect of a net zero global economy by mid century in sight.

As power systems integrate more digital and inverter-based devices, the guidelines and technical standards for these resources are evolving, and none as quickly and urgently as cybersecurity standards. New approaches to cyber defence are now needed to protect more interconnected systems with diverse owners, manufacturers, and system architectures. However, current cybersecurity standards for energy devices are still patchy. Upcoming efforts are aimed at changing that, reports NREL’s Connor O’Neil.

Simply Energy on Thursday announced it will be extending its Virtual Power Plant program across the eastern seaboard and opening it up to five different battery brands. Simply Energy will continue its technology partnership with SwitchDin to do so, with Ryan Wavish, Simply’s General Manager, and Andrew Mears, CEO and founder of SwitchDin, telling pv magazine Australia they plan to introduce a whole range of new, more advanced features into the VPP as the relationship between the two companies evolves.

Western Australia has today announced the launch of its $35.5 million Virtual Power Plant trial, Project Symphony, which will examine the ways in which residents, utilities, and network operators can join forces to centrally orchestrate the output of rooftop solar, batteries and other distributed resources to best serve both customers and the grid at large.

Western Australia has become the second state to give network operators the capacity to remotely switch off residential solar systems as an emergency grid stability mechanism.

Scientists in the United States pieced together data from hundreds of different sources, looking to establish the key factors that have led to consistently falling prices for lithium-ion technology since their commercialisation thirty years ago. They find that public-funded research, primarily in chemistry and materials science, has made the largest contribution to cost reduction. And they offer suggestions on policy and investment to ensure that the research can continue to make these important contributions to reduction in battery costs.

NREL scientists have unveiled a storage system based on a phase-change material that can store both thermal energy and electricity in a single device. According to the researchers, the new technology may be used to store excess electricity produced by on-site solar or wind operations in large scale buildings.

Brisbane-based startup Evos has unveiled its first electric vehicle charger, boasting simple installation and transportability as well as the company’s own energy management software. The charger will be available from next month.

COP flack for Australia’s insubstantial and unstructured response to decarbonisation has not made the country more attractive to investors. Has our first-mover status cruelled our investability, and what could the next Federal Government do to revive investor confidence?
