With the increase of wind power capacity, wind energy is now becoming an essential part of energy production system. High wind power penetration may increase the instability of grid due to the characteristic of wind. Fortunately, with the development of power electronics, it is possible to provide a relatively stable energy production by applying power electronics to wind turbine. Due to the complexity of wind turbine, a generic dynamic model of wind turbine can be helpful. The objective of the work is to develop a general wind turbine models that can be used for investigations. The report had tracked the theory of wind turbine and its development, three different kinds of wind turbine are included, which are fixed speed wind turbine, variable slip wind turbine and doubly-fed induction generator wind turbine. Fundamental working theory and a model built by Matlab was provided for each of technology. Assessment for the models was done to prove that it has the ability to reflect the characteristic of wind turbine. Despite from that, the models were done in three phase, so it has the ability to do with load flow analysis or grid stability.
