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

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.

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
