With increasing concern over climate change and the security ofenergy supplies, wind power is emerging as an important source ofelectrical energy throughout the world.
Modern wind turbines use advanced power electronics to provideefficient generator control and to ensure compatible operation withthe power system. Wind Energy Generation describes thefundamental principles and modelling of the electrical generatorand power electronic systems used in large wind turbines. It alsodiscusses how they interact with the power system and the influenceof wind turbines on power system operation andstability.
Key features:
* Includes a comprehensive account of power electronic equipmentused in wind turbines and for their grid connection.
* Describes enabling technologies which facilitate the connectionof large-scale onshore and offshore wind farms.
* Provides detailed modelling and control of wind turbinesystems.
* Shows a number of simulations and case studies which explainthe dynamic interaction between wind power and conventionalgeneration.
