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). 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) s ....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). 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
Advanced Modular Reconfigurable Energy Storage and Conversion Systems. 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 usin ....Advanced Modular Reconfigurable Energy Storage and Conversion Systems. 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
