Power strategies for maximum control structure of a wind energy conversion system with a synchronous machine

Bouscayrol, A.; Delarue, Ph.; Guillaud, X. - In: Renewable Energy 30 (2005) 15, pp. 2273-2288

The control of a wind energy conversion system can be decomposed into two parts: a local control depending on the power … structure and a global control (strategy) deduced from global considerations. The local part ensures an efficient energy … management of each component of the system. The local control structure can be deduced from the Energetic Macroscopic …
