New topologies optimised for co-located grid connected photovoltaic (PV) and battery storage systems. 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).

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

The project aims to develop advanced, modular, reconfigurable energy conversion systems utilising lithium-titanate batteries. Battery energy storage is critical to energy security and integration of increased renewable generation with the electricity grid. However, its high cost prohibits its wide commercial acceptance. The proposed system avoids a large number of series connections of batteries and raises the voltage by using series connection of high-frequency isolated converters for transformerless interconnection of such battery energy storage systems with the grid. The project outcomes include new grid support technologies.Read moreRead less
Regulation of the Cell Bus Voltages of Large Scale Modular Multilevel Converters: Advanced Energy Converters for Future Electricity Grids. Large scale power electronic converters are essential to the emerging “Smart Grid” electrical distribution networks, using large numbers of cascaded cells to operate at the very high voltages that are required for direct grid connection.

Large scale power electronic converters are essential to the emerging “Smart Grid” electrical distribution networks, using large numbers of cascaded cells to operate at the very high voltages that are required for direct grid connection. At present, the fundamental factors that drive the fluctuations of the cell DC link voltages, including in particular the complex non-linear interactions caused by the physical cell switching processes, are very poorly understood. This project will use a new harmonic analysis strategy to investigate the basic engineering science that underpins this voltage fluctuation phenomena, to achieve a quantum step in the understanding of the fundamental operating processes of large scale cascaded converters.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

Recent occurrences of blackouts around the world caused immeasurable damage to electrical network hardware in the range of $10M, however, the losses from an unavailable network are much more. The CIs and Zenergy Power Pty Ltd (formerly Australian Superconductors) have been developing saturated core fault current limiters (FCL) since 1999. The first saturated core fault current limiter employing the Australian's entity's technology was installed in California. The aim of this proposal is to extend this technology to demonstrate next generation FCL using a newly developed superconductor magnesium diboride (MgB2) wire which is cheaper and easier to manufacture than high temperature superconductors and the CIs' group hold strong IP on nano-scale chemically doped MgB2 wires.Read moreRead less
