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.
