This paper proposes a new control scheme for a permanent magnet synchronous generator (PMSG) based wind energy conversion system (WECS). In this scheme, the generator and grid currents are controlled using a hysteresis current controller (HCC). The control system of the back-to-back converter based on the HCC is described. Modeling and simulation of the system are developed using Matlab/Simulink to...
The paper deals with a Second Order Variable Structure Control (VSC) for Wind Turbine PMSG-based and Generator-side Converter System. By means of the proposed control and the associated sliding observer, a vectorial control of PMSG generator is recognized while maximum power point tracking by the renewable source and DC voltage control of the generator-side converter are assured to maintain a high...
This study developed a methodology to determine zones of acceptable voltage profiles for wind power generation connected to distribution systems. Three load profiles (residential, commercial and industrial) connected to the distribution network were analyzed considering the impact on voltage levels and steady-state stability for different wind speeds and wind generator control strategies. The wind...
The purpose of this paper is to present a design of digital hysteresis current control circuit in ac-dc converter for wind power generation. The control circuit utilizes a digital signal processor and an analog reactor current detector using an RC integrator. In the proposed method, the design of time constant of RC integrator is important to determine the operation range of duty ratio. The design...
This paper presents the development of forecast models for a wind farm producibility with a 24 hours horizon. The aim is to obtain accurate wind power predictions by using feedforward artificial neural networks. In particular, different forecasting models are developed and for each of them the best architecture is researched by means of sensitivity analysis, modifying the main parameters of the artificial...
