This course will provide a presentation of the electrical subsystem for important distributed generation technologies. The main focus will be on wind turbines and photovoltaics. The analysis of grid interconnection issues, assessment procedures and methodologies will also be discussed. This will cover typical interconnection schemes, power quality and fault level considerations and protection requirements. The course will also provide a presentation of the latest grid-code requirements for the connection of large wind farms. This will address basic requirements regarding fault ride-through, active and reactive power regulation, as well as their fulfillment by the technologies available today. Finally, the course will presentat the latest developments in microgrids and discussion of grid integration issues in autonomous island power systems.
