Effect of Wind Speed and Load Correlation on ELCC of Wind Turbine Generator

Utilization of wind turbines as economic and green production units, poses new challenges to the power system planners, mainly due to the stochastic nature of the wind, adding a new source of uncertainty to the power system. Different types of distribution and correlation between this random variable and the system load makes conventional method inappropriate for modeling such a correlation. In...

Harmony search method for optimal wind turbine electrical generator design

The Harmony Search (HS) method is an emerging meta-heuristic optimization algorithm, which has been employed to cope with numerous challenging tasks during the past decade. In this paper, the essential theory of the HS algorithm is first described in details. Next, a few typical variations of the HS method are explained. The application of the HS in a practical wind turbine electrical generator...

Residual Generator Fuzzy Identification for Wind Turbine Benchmark Fault Diagnosis

In order to improve the availability of wind turbines, thus improving their efficiency, it is important to detect and isolate faults in their earlier occurrence. The main problem of model-based fault diagnosis applied to wind turbines is represented by the system complexity, as well as the reliability of the available measurements. In this work, a data-driven strategy relying on fuzzy models is...

Doubly Fed Induction Generator Systems For Variable Speed Wind Turbine

This paper presents results of a study concerning the dynamic behaviour of a wind energy system powered by a doubly fed induction generator with the rotor connected to the electric network through an AC-AC converter. A tendency to put up more and more wind turbines can be observed all over the world. Also, there is awareness in taking into account the requirements of a clean environment, due to...
