Distributed energy resourcesProject Horizon Power Business Model Pilot Phase 1
This Technical Report provides an overview of the data acquisition systems and results of studies into PV fluctuation and voltage rise on the Carnarvon distribution network.
In 2017, Horizon Power commenced the ‘Distributed Energy Resources (DER) trials in Canarvon’, Western Australia, in partnership with researchers from the Engineering and Energy Discipline at Murdoch University. The trials aims to resolve the technical, operational and transitional barriers to a high penetration DER future.
Carnarvon, situated 900 km north of Perth, experienced a rapid uptake of solar PV with higher than average system sizes (typically 10-30 kW) in 2008 – 2011. As part of this project, unique monitoring infrastructure (Wattwatchers (WWs)) were installed on a sample of distributed PV systems capturing more than half of the aggregated output of all PV systems in Carnarvon. For the analysis period November 2017 to November 2018, data collected from this representative sample was used to determine and review fluctuation and diversity factors currently used in Horizon Power’s approach to determining PV hosting capacity on their networks.
