Wind power generation is making an increasingly significant contribution to global electricity
production. The high penetration of wind power greatly affects the stability of modern power …

To maximize power extraction at below-rated wind speeds, variable-speed wind turbines
must be controlled by tracking the optimal TSR (tip speed ratio) and pitch angle, which …

This paper studies the time-scale characteristics, model reduction, and oscillation stability of
the grid-connected variable speed pumped storage unit (VSPSU). Firstly, a method based …

To improve power production and reduce loads on turbine components, exact wind speed
information is required in modern wind turbine controllers. However, the wind speed …

The main objective of this study is to improve the energy quality extracted by variable speed
wind turbine based on doubly fed induction generator. First, the dynamic modeling of …

Burgeoning demand for additional energy sources to supplement existing fossil fuel
supplies has increased the requirement for efficient and cost-effective renewable energy …

In this paper, a novel control mechanism is presented for the control of variable speed wind
turbine (VSWT) with a fractional-order doubly fed induction generator (DFIG) to extract the …

In this article, using singular perturbation theory and adaptive dynamic programming (ADP)
approach, an adaptive composite suboptimal control method is proposed for linear …

This paper presents a decentralized composite suboptimal control strategy to solve the
optimal control problem for a class of two-time-scale networks, which consist of m lower …

In this paper we study the order reduction of a wind turbine model using the methods of
balancing transformation and singular perturbations. We show that the order of the …
