Wind turbine generators represent a valid and sustainable alternative for a significant energy provision, which is increasingly demanded by the planet, and a number of generator models have been proposed for supporting their design. However, equatorial regions have very special conditions for their gravity and wind behavior. Therefore, we present here a new wind turbine-generator model suitable for...
Wind energy, a kind of renewable and clean energy, is widely studied nowadays. Directly driven wind turbine permanent magnet synchronous generator (D-PMSG) plays an important role in the modern wind generating systems. A reliable and speedy simulation of the wind directly driven permanent-magnet synchronous generator is significant. By replacing the power electronic device with math equivalence, it...
This paper describes the design, modeling and development of a novel Airborne Wind Energy system (the EAGLE System), designed to handle a 2.5 kW, 25 kW or 100 kW aloft generator at varying altitudes. The system combines a hybrid tethered lighter-than-air and aerodynamic lift based flyer supporting a counter-rotating wind power generator payload, and a nonlinear-robust MIMO control system, with longitudinal...
Nowadays, technology evolution and deregulation of the electric utility industry enable distributed generation (DG) to play an increasing role in satisfying locally the power demand. In this paper, an optimal control method for variable speed wind turbines (VSWTs) in islanded mode of operation is presented. Aim of this control system is to minimize the necessary control action in order to track the...
As wind turbines continue to grow in size and flexibility and are deployed in more hostile environments, the need to develop advanced control schemes will be elemental to deliver the lowest possible energy costs. This paper explores controller design based on modeling the wind speed as a stochastic process, and the wind generating system (WGS) as a multi-mass system with a soft shaft linking the turbine...
Recent advancements in size and technology of wind turbines require sophisticated control systems to effectively optimize energy conversion and enhance grid integration. This article investigates output power stability of a WECS in a highly fluctuating wind environment. The aim is advanced controls development to identify and assess the critical loads and instabilities, and improve the dynamic response...
