Modeling and analysis of a grid-connected wind energy conversion system using PSCAD/EMTDC

This paper presents the modeling and analysis of a grid-connected wind energy conversion system (WECS) using PSCAD/EMTDC. The modeled system is characterized and analyzed for validation. An inverter control algorithm for effective power control is also proposed and evaluated, resulting in an efficient active power control that extracts the maximum power from the wind turbine. The controller also controls reactive power for load variation and aerodynamic models are applied for a wind turbine model. All analysis and evaluation have been conducted for a 1 MW power system with 22.9 kV.
