Project SHIELD – Synchronising Heterogeneous Information to Evaluate Limits for DNSP

Summary

Need

Project SHIELD was a response to support networks grappling with the challenges posed by the growth of DER, particularly rooftop solar. This project utilised real-time data to assess how much DER can connect to the grid, rather than the current practice of relying on static and conservative limits. The objective was to maximise the hosting capacity of the existing network.

Action

Together with University of Queensland, GridQube Pty Ltd, Essential Energy, Ergon Energy and Energex, Luceo Energy developed a software platform compiling data from network infrastructure, smart meters and smart consumer-owned energy assets such as batteries and inverters.

Desired outcome

The aim of Project SHIELD was a proof-of-concept platform that allows networks to assess how much consumer-owned energy can safely be connected to the electricity grid without additional investment in infrastructure, rather than the current practice of relying on static and conservative export limits.

Results

The Project demonstrated the potential of heterogeneous data and state estimation to enhance network visibility, optimise DER integration, and support more dynamic and flexible network operations.

The lessons learned from the project underscore the importance of data acquisition, the value of open-source and non-traditional data sources, and the need for continued innovation in network management.

While the costs of acquiring and managing data remain a significant challenge for DNSPs, strategies for mitigating these costs include the use of state estimation and the integration of heterogeneous data. As the energy landscape continues to evolve, DNSPs will remain adaptable and continue to explore new approaches to data acquisition and network management to ensure a reliable and sustainable energy transition
