Consumer-Led Transition Australia's World-Leading Distributed Energy Resource Integration Efforts I IT'S A SUNNY SPRING DAY in South Australia. A light breeze is cooling the coastal state capital of Adelaide as approximately 260,000 distributed solar photovoltaic (D-PV) systems on residential and business rooftops generate electricity, setting a new state record for the lowest minimum electrical demand for the third time this season. All looks peaceful throughout the suburbs. D-PVs form an irregular yet persistent patchwork across one-third of the houses in the state. Most consumers are going about their day without a glance at the D-PV panels on these roofs. However, the mild temperature and bountiful sunshine lead the D-PV generation to climb, causing the voltage to creep higher and power to flow in reverse across large swathes of the distribution network. Some D-PVs are tripping off, unbeknownst to their owners and the local network operator. The Australian Energy Market Operator (AEMO) is tracking falling demand and monitoring the proportion of Digital Object Identifier 10.1109/MPE.2020.3014720 Date of current version: 16 October 2020 20 ieee power & energy magazine ©SHUTTERSTOCK.COM/ARTHIMEDES synchronous generation in the South Australian interconnected region. Engineering teams are assessing the potential power system security implications of D-PV behavior during possible contingency events. The state's distribution network operator is observing and managing the changing voltages and flows through the system. Other teams continue their work on developing innovative planning and operational 1540-7977/20©2020IEEE november/december 2020http://www.SHUTTERSTOCK.COM/ARTHIMEDES
