Development of a microgrid design tool: consumer selection, electrical sizing, and economic feasibility analysis

This thesis presents an open and modular workflow for rural microgrid planning that com- bines geospatial processing in QGIS with MGDOt—a research-stage MILP optimiser. MGDOt is run at hourly resolution in both economic-dispatch and DC-OPF modes to generate sizing, operational, and economic outputs,...
