Steven Humphries developed a traditional load control system that absorbs solar photovoltaic (PV) energy and e ectively acts as a ‘solar sponge’.

This is coupled with the standardisation of demand response in Electrical Energy Storage (EES) systems.

The solar sponge switching program enabled controlled electric hot-water load, to clip the morning peak and fill the trough during the middle of the day.

Network utilisation was improved and customer inverters could continue to feed into the network retaining customer feed-in-tariff earnings. Availability of hot water for customers was also maintained.

Australia is one of the best places to see the advantages of graphics processing unit (GPU) modelling, according to Monika Balicki.

A prime example is her work in Toowoomba in 2015 as part of an update to the region’s planning scheme, a massive project covering nearly 13,000 km2 that includes the Condamine River floodplain in Queensland.

The council saw a need to update its model, as new technology only available in the last two years would improve flood-mapping accuracy.

New light detection and ranging (LiDAR) survey data, in addition to advances in GPU technology, made it possible to develop a comprehensive map of  flood elevation surfaces, velocities and depths, as well as flood hazard and hydraulic categories for a full set of modelled events.

“New LIDAR data made it possible to develop a map of flood elevations.”

GPU 1D and 2D flexible mesh modelling allowed Balicki to adjust the resolution to be more detailed in areas of interest, such as towns.

The SEN Integrated Renewable Energy Networks (SIREN) Toolkit power modelling so ware was developed as an open sourced package which is free to use, modify and/or redistribute under the terms of a General Public License.

The software enables the user to develop real-time; location-specific modelling of renewable energy generation and of dispatchable balancing generation to produce scenarios for reliable, stable electricity grids with a mix of renewable technologies.

The SIREN software represents an advance in rapid iterative economic modelling of renewable electricity networks. It provides a tool to raise renewable energy opportunities with energy planners, policy makers, politicians and the community at large.

“The software enables the user to develop real-time …modelling.”

Licensing the tool as open source enables other users to take advantage of the development.

Arup, Sydney Water and CSIRO developed a decision framework to compare and realise the benefits of potential water demand management activities.

The project included spatial analysis of potential high-benefit areas for specific targeting, and a Decision Support tool that quantifies the benefits.

Daniel Lambert led the development of the tool with a cross-disciplinary team and used digital technology to identify areas of opportunity.

The framework was informed by spatial mapping, data, and economic indicators.

Beer Opatsuwan took a lead engineer role on a signifi cant project across Energex and Ergon Energy to procure and implement high-voltage electrical equipment.

The initiative aims to reduce duplication and align the standards between the two Queensland-based electricity utilities.

He focused on creative collaboration in order to bring the best ideas out of his peers by road showing the equipment across 20 locations within South-East Queensland.

He also incorporated the impacts of procured equipment to the environment by factoring in SF6 gas volume, recyclability, suppliers’ end-of-life programs and other sustainability initiatives as part of the evaluation.

Mike Boyden has patented a retro-ft double glazing window system that has application in both residential and commercial buildings to reduce Australia’s energy consumption and greenhouse gas emissions.

The approach retro-fits glazing to existing windows and doors without the need to remove the existing window or window pane. The new glass panes are cut, drilled and prepared offsite.

Installation involves removing contact tap coverings and placement of the new window pane against the existing window pane.

Valves within the new pane allow it to be vacuumed into place. Once the pane is fixed, the vacuum is released and the space between the original or window pane and the new window pane is  lled with a thermally-e cient gas through a patented valve system.

Boyden estimates if 50% of Australian residences and commercial buildings were fitted with the retro fit double glazing system over a period of 10 years, then the saving to the Australian energy bill would progressively increase to $3 billion per year.

“Once the pane is fixed, the vacuum is released and the space filled with a thermally efficient gas.”
