051543 - ELECTRIC POWER SYSTEMS II
This course is aimed to introduce aspects and issues related to the design and operation of transmission and distribution grids, electronic converters for high power applications, the conversion of renewable sources and their interactions with the networks.
Risultati di apprendimento attesi
The course will allow the Students to know (DdD1):
the conversion of renewable sources, mainly photovoltaic and wind, into electric energy;
the high voltage direct current power transmission through modern power converters in the era of a high penetration of renewable sources;
the constructive parameters of the distribution and transmission lines and their influence on the electric parameters;
the analysis of the transient events, e.g. lightnings, their propagation and measurements for their mitigation;
storage systems and compensating devices to improve the quality of the power delivered to the end users in the presence unpredictable generation from renewable sources;
architectures of AC and DC grids and their comparison.
The training lessons will allow the Students to (DdD2 and DdD3)
prepare, present and discuss about the design issues, benefits and problematics related to renewable source generators in actual power systems;
use software tools to study and simulate distribution and transmission systems that can also include power electronic devices.
Technical visits to real high power systems will show to the Students the practical application of the theoretical aspects (DdD2)
1.: Renewable sources: this section is related to the electricity production from renewable primary sources, especially for wind and photovoltaic technologies modern solutions are highlighted. Besides, sizing criteria and criticalities of renewable sources are presented and discussed.
2.: HVDC transmission: this topic is focused on the modern High Voltage DC transmission systems, with LCC or VSC technologies, used for long-distance electricity transmission and to embed more renewable power plants in the transmission grid.
3.: Storage systems: these systems are currently under investigation for renewable generation dispatchability. In this part different technologies are presented and discussed applied to renewable sources.
4.: Transmission lines: the first part of this section is related to the calculation of the series and shunt line parameters. The second part is focused on the behavior of the transmission lines in different working conditions, both in transient and in steady state.
5.: Distribution systems: this section is focused on the medium voltage distribution systems, analyzing their different configurations, working principles and possible criticalities as intermittent arcs.
6.: Stability of systems: in this section the stability of both rotating machines and transmission lines is analyzed.
7.: Insulation coordination: the insulation coordination between different systems is discussed and presented using a statistical approach.
Room exercise lessons are dedicated to the sizing of renewable electricity generation, storage devices and transmission systems through practical exercises and simulation software tools.
Technical visits on real power systems complete the course.
Students are required to know basic knowledge of power distribution systems and advanced knowledge of electric circuit theory.
Modalità di valutazione
Final exam at the end of the course will be in written form.
Some questions on specific subjects will be asked to assess the knowledge of the theoretical aspects of the course (DdD1).
Moreover, a written test will assess the ability of the Student to link the theoretical subjects to the practical aspects (DdD2).
During this test, the Student will have to integrate the different aspects of the topics of the course to find the correct solution (DdD3).
A design project carried out during the training lessons will contribute to the final evaluation (DdD2).
