Abstract
Wind energy is pollution-free and renewable. Advanced control design for wind power generation systems represents a pivotal yet challenging research topic. Some sophisticated control schemes have been provided to ensure reliable and high efficient operation of wind turbines during various modes such as start-up, power production and protection shut-down. An overview on the latest developments in modeling and control of wind power generation systems is given in this paper. The main focus is on the effective operation of wind turbine in three well known modes covering safety: maximum power capturing, system protection and load impact reduction. Meanwhile, several key trends are discussed to demonstrate the possible solutions and feasibility of future implementation.
