Integration of large wind farms into utility grids (part 2 - performance issues)

This paper presents a discussion of the two major types of wind turbines, conventional induction generators and double-fed induction machines. Performance issues related to the dynamic behavior of both wind turbines are discussed. Example simulations from a major study of the integration of wind farms into a utility grid are presented to illustrate the performance issues discussed. In addition, a discussion is given on some of the potential interactions between wind turbine generators and other transmission equipment such as series compensation and HVDC; this is also illustrated with simulated examples.
