Interconnection and damping assignment passivity-based control of a PMSG based wind turbine

The use permanent magnet synchronous generators (PMSG) in wind turbines has been increasing considerably due to its efficiency, low maintenance costs and reliability. PMSG´s are connected to the grid by means of frequency converters. Generally a back-to-back full converter structure is preferred. This work intends to present system modeling and the application of interconnection and damping assignment passivity-based control (IDA-PBC) for a synchronous generator based wind turbine. The simulation results for the comparison between PI control technique in synchronous reference and IDA-PBC. A prototype of wind generation 3KW connected to the power grid was built in the laboratory to obtain experimental results for the IDA-PBC technique.
