This paper presents a general modeling and an experimental validation of a doubly fed induction generator (DFIG) based wind conversion system (WCS). The wind conversion system has been briefly presented. Then, the d q control of the grid side converter (GSC) has been detailed theoretically. Moreover, the decoupled active and reactive powers control of the DFIG has been presented. The last is carried...
A classical wind energy conversion system is usually a passive generator. Its power does not depend on the grid requirement, but entirely on the fluctuant wind condition. In this paper a DC-coupled wind/hydrogen/super-capacitor hybrid power system is studied. The purpose of the control system is to coordinate these different sources, especially their power exchange, in order to make the generated...
A multi-machine multi-converter system formalism has been proposed to describe systems composed of several electrical machines and converters. This description points out coupling elements, which have to distribute energy. Control structures have already been proposed for systems with downstream coupling. This paper is focused on control structures for systems with upstream coupling. Several solutions...
