Considerations Regarding the Modelling of Wind Energy Conversion Systems

Abstract: The above paper presents some considerations regarding the modelling of wind energy conversion systems (WECS). There are presented practical problems of grid integration of wind turbines, the usage of general system models, respectively of RMS (root mean squares) models. There are presented models of some WECS components and related, such as: a probabilistic 2D model for instantaneous wind velocities, aerodynamic model of wind turbine, rotating inertia model, asynchronous machine model, grid model. This paper only presents models used in different WECS, models that can be easily simulated with adequate simulation tools such as Matlab-Simulink.
