Optimising Off-Grid Microgrids in Remote Areas: The ‘Micro Reseau Mafate’ Project

International audience The development of autonomous microgrids presents a suitable alternative for electrifying isolated communities. However, to achieve truly virtuous solutions for environmental protection, a sustainable energy management system is highly recommended. This research project, located on Reunion Island, focuses on modelling the solar resource and user consumption profiles within a microgrid using specialised instrumentation. An innovative human-machine interface (HMI) is then developed and tested in a real-world configuration. This interface utilises a mathematical optimisation program to manage the microgrid effectively. The project meticulously examines the optimal operating point of the entire system, encompassing power generation devices, storage elements, and ultimately, household energy delivery. Tests have demonstrated that, in operational mode, the level of user acceptance of the management tool was highly satisfactory. The tool provides users with real-time information on the performance of the microgrid, which they found very helpful. This pilot program serves as a springboard for the future installation of numerous microgrids throughout this remote region.
