Description and contextualization of the subject
The widespread use of power electronic interfaces, required to enable the grid integration of renewable energies and increase the efficiency of electric loads, is completely transforming the traditional power system from being mechanically controlled, to being electronically controlled.
Most of the power flow, from generation to distribution and consumption, is currently processed by ac/dc and dc/dc converters. New converter topologies (such as multilevel converters) have entered the market and their design, operation and control need to be optimized for the specific applications.
The course will cover utility applications, ranging from Flexible AC Transmission (FACTS) devices to High-Voltage Direct Current (HVDC) systems and technology, as well as grid interfaces for Distributed Energy Resources. The role of power electronics for power quality enhancement, including reactive power compensation and harmonic filtering, will also be discussed.
The focus of the course will be on the operating principles, analysis, modeling and control of power electronic systems used in the above-mentioned applications.
The main objective of the course is to provide knowledge on the evolution of the modern power system, whose operation is increasingly challenged by the pervasive penetration of power electronic converters. A supplementary objective is to provide students with the ability to understand the increasing relevance of the role of control systems in relation to power electronics applications
