Wind Turbine Operation in... | Buy

This is a comprehensive approach to Wind Turbine Generator Systems (WTGS) and their operation in dynamic electric power system analysis. The presented advanced models arose from the authorÂ´s research. They describe the complicated dynamical system behavior of wind turbines much better than the over-simplified static models. In particular, the control structure is taken into account. This book provides advanced tools for design, projection and optimization of turbines and systems that have yet not been available.
