“…As described in Nunes et al, 18 a decoupled control is designed in this article to achieve the rotor speed and terminal voltage control. More details of the paradigm can be found in Nunes et al 18 and de Almeida et al 21 A great number of literature 18,21,23,26,27 involving the design of control schemes for variable-speed wind turbines, mainly focusing on PI controllers, have been published. In our work, the designed controllers are modelled as PI controllers which are similar to that of de Almeida et al 21 It should be noted that the integral element is superseded by lag-lead element for better system dynamic performance.…”

“…The dynamic behaviour analyses of DFIG based are given elsewhere. [18][19][20][21][22][23][24][25][26][27][28][29] Previous works [18][19][20] studied a model of a wind turbine with a DFIG for transient stability analysis to demonstrate the capability of the DFIG to maintain system stability following disturbances; 18 the more adequate mathematical models of DFIG suitable for transient stability studies 19 and the easier integration into the existing commercial simulation tool. 20 In de Almeida et al, 21 a control strategy realised by fuzzy controllers is applied to the rotor-side converter of the DFIG and the performances are compared with conventional PI controllers.…”

“…Vicatos and Tegopoulos 22 show a generalised analysis of the DFIG in the transient state during the three-phase short circuit from load condition. Other studies [23][24][25][26] discuss the influence of wind farms consisting of fixed-speed wind turbines and variablespeed wind turbines on the transient stability performance of the system to which they are connected. In Holdsworth et al, 27 a reduced-order dynamic machine model is derived suitable for modelling both fixed-speed and variable-speed with asynchronous DFIG wind turbines, and the performance during power system disturbances.…”

This paper shows a model of a doubly fed induction generator (DFIG) including a simplified model of a wind turbine for the purpose of transient stability analysis of large-scale power systems with great wind farms penetration. The wind turbine model and the DFIG model are systematically deducted in this paper.Specially,the improved model of rotor-side converter and the simplified grid-side converter model are considered in our work.The corresponding machine-network interface solution based on the synchronously rotating common x-y reference frame is elaborately issued in this paper. Furthermore, a method is proposed to calculate the DFIG initial conditions as well. A simplified model of the turbine is used excluding among other components the pitch control.Recently, renewable energy sources especially like wind energy are gaining significant interest throughout the world. Since the first wind turbine for electricity generation was developed, the corresponding technology has been widely improved step by step. [1][2][3][4] By the end of the 1990s, wind energy has re-emerged as one of the most important sustainable energy resources. It is known that the wind power is increasingly considered not only a means to reduce the CO 2 /NO x /SO 2 emissions generated by traditional fossil fuel-fired utilities, but also a promising economic alternative in areas with appropriate wind speeds. 5 Wind power is expected to play a comparatively significant role in the future national energy scene. As increasing of penetration levels of wind power, the assessment of the effects of the wind power penetration to an existing interconnected large-scale power system becomes very important and imperative. In the technical point of view, power system engineers have to confront challenge regarding the network integration of wind power, especially with the consideration of transient stability analysis. A great amount of literature have been published in investigating the dynamic behaviour of wind generator system in recent years. Malatestas et al. 6 and Stavrakakis and Kariniotakis 7 investi-
