There has been a rapid increase in the connection of distributed solar photovoltaic (PV) systems in Queensland over the last decade. This has led to a range of challenges for the distribution networks including reverse flows and voltage rise on distribution feeders which traditionally only supplied loads. As a result there has been an increased range in steady-state voltage regulation on the low voltage (LV) network. Reductions in LV levels to transition from the 240V to the 230V standard have helped reduce overvoltage, increasing PV hosting capacity. Ongoing increases in steady state voltage rise on distribution feeders, associated with rising PV penetrations, will continue to increase voltage regulation. This becomes problematic where voltages already swing significantly between the upper (253V) and lower (216V) statutory limits as is observed on rural networks and increasingly networks with high existing PV penetrations.

Peter Kilby– Intelligent Grid Engineer at Energy Queensland
Peter is an Intelligent Grid Engineer at Energy Queensland with a focus on distribution voltage management practices and the integration of high penetrations of DER. After completing a Bachelor of Engineering with honours in Electrical Engineering and a Bachelor of Science majoring in Physics in 2009, he joined Energex, the South East Queensland distributor, which later merged with Ergon Energy to become part of the Energy Queensland Group. He has worked in a range of areas including standards, substation design, voltage management and DER integration.
