Wind power plants have nonlinear dynamics and contain many uncertainties such as unknown nonlinear disturbances and parameter uncertainties. Thus, it is a difficult task to design a robust reliable controller for this system. This paper proposes a novel robust fractional-order sliding mode (FOSM) controller for maximum power point tracking (MPPT ...

The world is facing the challenge to generate and store electrical energy in an effective manner so the concentration of wind farm is increasing day by day. All these natural resources possess stochastic behavior so the variation in output waveforms at all these nonlinear power supply units are pre-default.

2011 IEEE Power and Energy Society General Meeting, 2011
The doubly-fed induction generators (DFIGs) are widely applied in wind power conversion. The wind turbines are operated under speed control or power control, and suffered from wind disturbance or network contingency. Full expression of each DFIG involves many differential equations and lots of calculation effort.

Modelling of a doubly fed induction generator (DFIG) to study its control system
A fifth order model of a doubly fed induction generator (DFIG) is proposed with stator flux orientation (SFO) vector control. Induction generator equipped with the as-built wind turbine scheme and grid system is modelled in MATLAB/SIMULINK. Different controllable parameters are identified.Billah, M. M. +2 more

Power Flow Modeling to Doubly-Fed Induction Generators (DFIGs) Under Power Regulation
IEEE Transactions on Power Systems, 2013With the constant kopt model under the maximum power point tracking (MPPT) strategy, wind power fluctuation from the doubly-fed induction generators (DFIGs) increases the operational risk. With given wind speed, the constant kopt model with variable slip yields impractical power output.
