Demonstration of Three Dynamic Grid-Side Technologies

closed

The Demonstration of Three Dynamic Grid-Side Technologies project aims to roll out three novel technologies and intelligent control systems to understand and demonstrate their ability to increase the uptake of distributed energy resources (DER) at the neighbourhood level, safely and cost-effectively.These technologies improve the ability of network operators to monitor the low-voltage network, while the intelligent systems proactively manage grid power and voltage to increase DER penetration.Key resultsThis project successfully assessed the viability of three technologies to increase the DER hosting capacity of two sites within Jemena and AusNet Services’ low-voltage distribution networks in Victoria.The project confirmed that:dynamic and active management of electricity distribution networks can unlock additional capacity to host DERs.PSDs could enable 59% more DER hosting capacity at the AusNet Services network site, further increased to 88% with the adoption of PCD technology. By contrast, the future DER hosting capacity could only be increased by 29% without any introduced grid-side technologies.PSDs could enable 8% more DER hosting capacity at the Jemena network site, with the potential for a 36% increase with combined PCD and BESS controls. DER hosting capacity could be further increased from to 64% if the terminal voltage of the distribution transformer was optimised.
