Obiettivi formativi

With the continuous significant increase of energy demand and environment issues renewable energy systems have become a critical research topic worldwide.

In this context, this course aims to provide students the key understandings, concepts, and principles of electrical power systems with the integration of renewable energy components. Specifically, the topics covered in this course will be renewable energy systems such as: wind system, solar power systems, tidal and waves sytems, distributed generation, storage technologies and others. This course will also introduce the latest research development on smart grid technology, such as the participation of distributed generation (DG) to ancillary service provision for the transmissione system operator (TSO).

The objective of the course is also to show how converter topologies are utilised in renewable energy systems (wind and PV), in utility applications (for example HVDC) and to further investigate the converters in terms of their efficiency, control characteristics, description of dynamics and their closed- loop control. Some advanced converter topologies, especially in the context of large and complex applications, which are beyond the scope of a first course in power electronics, are also treated.

At the end of the course, the student will be able to analize the renewable energy potential of a given place and sizing the relative generators. Further he can recognize the most common conversion chain and to operate as a system designer.

The acquired information will allow students to collaborate with experts in the project of renewable energy power plants.
