When a grid connected photovoltaic (PV) system and battery storage are co-located, many advantages can be gained by sharing and optimising the grid connection power electronics (DC-DC converters and DC-AC inverters). The specific aims of this project are to identify existing, and then develop and compare new, system topologies and configurations, for grid connecting co-located PV and (battery) storage in the low voltage AC distribution network. Different optimal solutions including new solutions are expected for single and three phase systems, for varying power levels from one kilowatt to one megawatt, and for varying load shapes (for example, residential vs commercial).Read moreRead less
Transition to Customer Response Driven Networks. The project seeks to develop an electrical network costing framework that appropriately rewards customers who act to reduce network stress. The solution to the existing explosion in distribution network costs is to develop customer-responsive solutions in demand management and use of storage. The aim of this project is to develop a framework for network costs that is driven by local congestion and which would reward customer-responsive solutions. ....Transition to Customer Response Driven Networks.

The aim of this project is to develop a framework for network costs that is driven by local congestion and which would reward customer-responsive solutions. The vision is that the aggregator would provide customers with communications/control equipment that would automate the changes in the responsiveness so that customer-generated load shifting would act to limit peaks.Read moreRead less

Bushfire safety improvements for rural electricity networks using hybrid fault detection incorporating distributed observations of travelling waves. Electrical faults in distribution networks can result in catastrophic bush fires. The existing fault detection methods are known to be incapable of detecting many faults. This project will develop improved protection methods that detect travelling waves produced by dangerous faults such as fallen lines and vegetation contacts.
Power quality monitoring of grids with high penetration of power converters. The project aims to monitor and analyse power quality of grids within the frequency ranges of 0-2 kHz (existing regulations) and 2-150 kHz (new regulations). Power quality of grids deteriorate due to the high penetrations of inverter-based renewable energy systems. To estimate power quality of grids, the project expects to develop a multi-domain simulation model based on power grid configurations and operating condition ....Power quality monitoring of grids with high penetration of power converters. The project aims to monitor and analyse power quality of grids within the frequency ranges of 0-2 kHz (existing regulations) and 2-150 kHz (new regulations). Power quality of grids deteriorate due to the high penetrations of inverter-based renewable energy systems. To estimate power quality of grids, the project expects to develop a multi-domain simulation model based on power grid configurations and operating condition. Developed methodologies will assist network service providers to better analyse harmonics and resonances within low and high voltage power systems. Expected outcomes of this project are to assist partners to monitor and solve the existing communication issues of audio frequency load control and to address power quality issues arising from the increasing connection of renewable energy systems.Read moreRead less
Degradation conscious grid-scale battery energy management scheme.

The project aims to develop an improved battery management system to smooth the intermittent contribution of renewable energy sources to the grid. As the level of penetration of renewable energy sources into electrical grids increases, energy storage will play an increasingly important role in solving some of the technical challenges caused by the intermittent nature of the renewable sources. The existing design methods for grid-scale battery management systems do not take into consideration the degradation of the battery banks. Thus, this project aims to fill this gap by developing an electrochemical-based, degradation-conscious, battery management system. The proposed system aims to increase the life span and capacity use of the batteries.Read moreRead less
Investigation of stability and power quality issues from the wide spread photovoltaic integration into electricity distribution networks.
