Apply intelligent control strategy in wind energy conversion system

The wind energy conversion system (WECS) was a strong nonlinear system. The wind energy parameters of wind farm possessed high stochastic, various uncertainties that weren't exactly recognized. As this kind of system had unmodel or does not have accurate modeled part, it was very difficult to be controlled effectively. The self-features and merits of intelligent control methods were extremely suitable for WECS. The main achievements and methods of fuzzy logic control, neural network control, expert system control and synthesis intelligent control used in the control of WECS stability, speed control system and maximum-power transfer were surveyed. Some certain problems to be solved were proposed simultaneously.
