About the research project

DC nanogrids have been rapidly developing to deliver clean energy to non-electrified and offshore settings. DC nanogrids consist of renewable energy sources such as solar PV and fuel cells and energy storage devices such as batteries and supercapacitors to provide energy efficiently and reliably. Unidirectional and bidirectional power converters are typically employed to integrate PV and battery and provide stable power to loads. This architecture offers greater control flexibility and easy implementation; however, resulting in high cost and low power density. Three port power converters with at least one bidirectional port are an optimal solution to overcome these shortcomings. However, designing three-port power converters featuring voltage control and power management of each port with a simple control strategy while achieving high efficiency, high reliability, and low cost is challenging. Therefore, finding an optimal commercially available solution is difficult. This project focuses on designing and developing novel three-port power converters topologies and control strategies with high efficiency, high power density and low cost. The project involves deriving, modelling, simulating, prototype building and experimental testing the proposed topologies to validate the performance.
