Rotating Frame, Average Value Converter Modeling: Basic principles in building analytical models

Electrical power converters have become indispensable units in modern power systems, with an increasing number of installations, application fields, and ratings. They are used for power conditioning; for controlling network, regulating generation, or load power; for integrating storage systems; and importantly for integrating most renewable energy plants. As a typical example, a modern wind generator will have two ac–dc converters back-to-back connected, facilitating optimal energy extraction from variable speed wind turbines and ensuring that the power plant meets network connection requirements.
