Application des Bond graphs à la modélisation et à la commande de réseaux électriques à structure variable

Abstract : This thesis concerns the problem linked to the association of the main components of an electrical network.The inductive nature of the elements to be connected involved some problems for their association through a common connection node. Two solutions are proposed to solve this problem and thus make possible the simulation. One solution accepts the presence of derivative causality in the global model, the second one consists in simplifying the models by removing locally dynamic modes to facilitate their association.The graphical description of causality in the global model of a micro grid with variable structure shows up that different configurations are possible, with different behavior and functioning for the components in each case.The bond graph tool has been chosen for modeling the different components, analyzing the model properties and designing control laws based on inverse models derived from bicausal bond graph. Robustness to parameter uncertainties of the electronic power converter control law is analyzed in a traditional way, by varying the load connected to the power converter. The control law is validated by simulation and experimentally
