Control of Grid-Forming Power Converters

This thesis focuses on the study of converters for microgrids. These are small-scale grid which can supply local loads, by using distributed generation. The goal of this project is the analysis, simulation and experimental validation ofMG converter control strategies. Moreover, an experimental testbench consisting of multiple converters has been assembled. First, different strategies of grid-forming control were analysed, implemented and then experimentally tested using a three phase two level inverter. Subsequently, a converter prototype was designed. This design involved both the mechanical structure (Solidworks) and the firmware implementation on a interface FPGA board. Finally, the complete system has been assembled and tested.
