Modeling, Parameter Measurement, and Control of PMSG-based Grid-connected Wind Energy Conversion System

The design of reliable controllers for wind energy conversion systems (WECSs) requires a dynamic model and accurate parameters the generator. In this paper, parameter measurement control direct-drive variable-speed WECS with permanent magnet synchronous generator (PMSG) are presented. An experimental method is developed measuring key PMSG. measured used in controllers. generator-side converter controlled using vector scheme that maximizes power extraction under varying speeds.
