Exploring the grid participation of Distributed Energy Resources within the Australian Capital Territory.
Following on from the success of the ARENA-funded evolve project, the ANU Battery Storage and Grid Integration Program and partners will be demonstrating the next step to dynamic operating envelopes, called ‘shaped operating envelopes’ in the ACT-based Converge project.
As more and more Distributed Energy Resources (DER) enter the electricity system, in particular the millions of rooftop solar assets across Australia, congestion management is a major issue for electricity networks. Shaped operating envelopes not only allow more DER to safely enter the system without breaching thermal and voltage limits, but also supports greater integration and market participation of DER.
“We know that rooftop solar is a valuable asset that can provide a range of benefits to customers and network operators,” said Andrew Fraser, Head of Engagement, Standards and Regulation at the ANU Battery Storage and Grid Integration Program. “Through this project we aim to demonstrate the next step in smart software technology. We will do this by demonstrating how shaped operating envelopes can let DER get the most out of the grid. With Shaped Operating Envelopes we can do things like enabling community energy batteries to increase the amount of solar exports, or increasing the amount of energy a virtual power plant can provide into the energy system.
“As with evolve, the software we develop will be open sourced, effectively allowing the knowledge that our research produces to be shared nationally and internationally with other Distribution Network Service Providers and utility companies,” said Andrew.
In keeping with the Battery Storage and Grid Integration Program’s techno-economic-social approach, Converge will also include a comprehensive social science research investigation to better understand the perspectives of end use electricity customers and market participants operating in the high-uptake DER energy system, that is the current Australian electricity system.
“The old paradigm was to design energy technologies without consideration of social impacts or public values,” said Hedda Ransan-Cooper, Leader, Social Science Research, Battery Storage and Grid Integration Program. “The energy sector increasingly realises that this can lead to unintended negative impacts, or that users will simply not participate in ways they had imagined. This project builds on our broader research agenda around understanding how public values such as ‘efficiency’ ‘fairness’ ‘environmental stewardship and ‘reliability’ can be integrated into technology design,” said Hedda.
Converge will entail full coverage of the ACT electricity market, with over 200,000 customers. The project emerged from a Memorandum of Understanding between the ACT Government and Australian Energy Market Operator (AEMO) to develop a national technology sandbox for testing new capabilities for supporting the integration and market participation of DER.
