This project is a joint IAP project with Katholieke Universiteit Leuven, Universiteé de Liège, and other foreign universities. The prime object of the project is to focus on modelling and managing complete electrical energy systems (multiple electrical energy devices linked through the electric grid), based on the measurements and the solution of inverse problems. Understanding this multiscale behaviour is becoming increasingly important as the power grid evolves into a complex system of interconnected distributed generation and electronically controlled loads.
