The Switched Reluctance Generator (SRG) has been widely studied for Wind Energy Conversion Systems (WECS). However, a major drawback of the SRG system adopting conventional control is slow response DC link voltage controller. In this paper, Proportional Resonant (PR) strategy proposed to output improve fast response. model high non-linearity, which makes design controllers difficult task. For r...

This paper presents system stability analysis of DFIG based wind energy conversion system. Presently for variable wind speed DFIG is considered as efficient machine to generate the power. In addition to this advanced AC/DC/AC converters with closed loop control system has been presented. For stability analysis 1.5MW wind turbine has been considered. As the speed of the wind varies by ± 18% to 2...

Power Generation from Renewable energy sources like wind, solar, geothermal, biomass, and hydro is predominant now days and among the renewable energy sources, small hydro and wind energy have the ability to complement each other. For Power generation by small or micro hydro as well as wind systems, the use of squirrel-cage induction generators (SCIGs) is mostly adopted. As regards in recent ye...

In this paper, modeling of doubly fed induction generator (DFIG) based wind energy conversion system (WECS) and speed controller are presented. The System Identification Toolbox MatLab is used to develop the linear model WECS by considering as input output. Two models, namely Auto Regressive with eXogenous Input (ARX) Auto-Regressive Moving Average (ARMAX), estimated. We ARX221 structure best f...

In a wind energy conversion system (WECS), changing the pitch angle of turbine blades is typical practice to regulate electrical power generation in full-load regime. Due turbulent nature and large variations mean speed during day, rotary elements WECS are subjected significant mechanical stresses fatigue, resulting conceivably failures higher maintenance costs. Consequently, it imperative desi...

The wind power generation has become more important nowadays to meet the increase in demand. DFIG based is recent and used many countries due its better controllability. controllers like Proportional Integral (PI) are for stabilization of waveforms supply system. change produces oscillation damping days. effect varying input generate using turbine resulting instability system because control do...

This paper aims to present and compare two techniques used smooth the injected power in grid from a doubly-fed induction generator (DFIG) based conversion system. The first technique on an inertial storage system while second is founded limiting captured by wind turbine. overall composed of energy (WECS) allowing convert into electric power. It controlled converters, side converter rotor conver...

Recently, Direct current (DC) microgrids have gained immense popularity due to their dependable and efficient framework, as well high transmission efficiency low electric power conversion. However, the non-linear nature of Renewable Energy Sources (RESs), increased presence electronic devices sudden load changes leads onset stability issues in DC microgrid. Thereby, a microgrid structure includ...
