This paper presents the development of Wind Turbine Emulator (WTE) for wind energy conversion systems (WECS), using a separately excited DC motor, controlled by a chopper and real-time interface card. The DC motor is controlled using PI regulator. The wind turbine emulator system includes wind speed profiles, mathematical model of wind turbines, modeling of rotor blade characteristics and modeling of rotor inertia. Wind speed can be easily programmed. The proposed approach was implemented on DS1104 real- time interface card and Matlab/Simulink real-time control programming. The experimental results show the performance of proposed WTS. © 2013 IEEE. Source

In this paper, a control of a variable speed wind generator (VSWG) system based on a doubly fed induction machine connected to the network associated to a flywheel energy storage system (FESS) is considered. The maximum power point tracking (MPPT) method, the independent control power of generator, the grid connection, and the control of flywheel energy storage system are studied. The flywheel energy storage system consists of a power electronic converter supplying a squirrel-cage induction machine coupled to a flywheel. This study investigates also, the possibility to compensate the reactive power. In order to validate the control method and to show the performances of the proposed system, its model is simulated for different operating points. Source
