Abstract
This paper attempts an as exhaustive as possible review of the control methods dedicated to optimizing the dynamic behavior of variable-speed wind energy conversion systems (WECS) from various viewpoints. Different performance criteria can be defined for WECS - e.g., the energy optimization can be achieved by operating the system at variable speed. The exploitation experience and grid-integration of WECS has presently concluded the necessity of solving multi-purpose optimization problems, which require advanced control approaches being employed. Some of the most pertinent approaches belonging to this trend and implemented by variable-speed operation are overviewed and assessed here, that allows for suggesting future research issues and perspectives.
