Control of a Wind Energy Conversion System using the Energetic Macroscopic Representation

This paper presents utilization of the Energetic Macroscopic Representation (EMR) which is a graphical formalism tool to analyze the behavior of a wind energy conversion (WEC) system based on a permanent magnet synchronous generator (PMSG). The aims of this paper are showing the clarity of this tool in the representation of complicated energy systems and the effectiveness of the control strategy deduced from this representation. More precisely, this paper starts from a synoptic with a simple knowledge of a wind energy conversion system to deduce a diagram for the control law based on the action and reaction principle. The methodology of this tool is described in details and the simulation results obtained in MATLAB environment are presented.
