Steady-state analysis of doubly fed induction generators for wind turbines using MATLAB
A wind energy conversion system (WECS) differs from a conventional power system. The power output of a conventional power plant can be controlled whereas; the power output of a WECS depends on the wind. This nature of WECS makes it difficult for analysis, design and management. Various approaches have been developed to study the behaviour of WECS. In this paper, the steady-state characteristics ...

Productivity of small wind turbines for various wind potentials conditions: application in Bulgaria and Corsica
Less or more accurate power curve models are generally used to simulate the wind turbine electrical production versus the available wind speed. However, if such models are adapted to large machines, this is not the case for small ones. The objective of this paper is to study the impact of different small-scale wind turbines power curves and wind distributions on the electrical production. An ...
