A hybrid power system (or micro-grid) may be composed of different energy sources, including renewable sources, loads, storage equipment, electrical / electronic converters, a central controller and local controllers. The microgrid can operate either connected to the main electrical grid or isolated from it in island mode. The following transition modes may take place: Disconnection from the grid to start island operation and reconnection to the grid alter island operation. The first transition mode, disconnection from the grid, is studied in this project.

The Project is a cross border cooperation project funded by the Aquitaine-Euskadi cooperation common fund with participation of the Ecole Supérieure des Technologies Industrielles Avancées (ESTIA) from Bayonne (France).
