Ing Ind - Inf (Mag.)(ord. 270) - MI (475) ELECTRICAL ENGINEERING - INGEGNERIA ELETTRICA
052589 - ELECTRICITY MARKETS
The course aims to provide a deep understanding regarding the liberalization process of the electricity sector and its evolution in a liberalized environment.
In the first part, tools to understand the process of liberalization of the electricity sector, the requirements and the conditions necessary for an efficient electricity market will be provided. Different market structure are compared and analyzed. Afterwards, models for price and power market analysis will be introduced.
In the second part, emphasis will be given to the European electricity market: the problem of the market coupling in Europe is analyzed and the evolution and the projects regarding the integration of the different market sections (day ahead electricity markets, intraday markets, and ancillary services markets) is analyzed.
Finally, starting from the liberalization of the Italian electricity market, due to the Bersani Decree, the complex framework that characterizes this market and its rules will be described and critically analyzed.
The subjects are organized in theoretical lessons and practical (numerical) lessons.
Then, a simulation of the pool market paradigm will be organized and the students (divided in teams) will assume the role of a generation company. Each team will have to define the strategy and will have to submit offers in the market. This simulation will be repeated several times to give the possibility to learn and understand the best strategy for its own generation company.
Risultati di apprendimento attesi
The course will allow the students to know (DdD1, DdD4):
what are the prerequisites for the liberalization of the electricity market;
what are the market structures in the electricity sector;
how the technical constraints (due to the generation plants and the electricity grid) influence the design of the electricity market;
what are the different approaches to represent the network in the market models;
the evolution of the market paradigms due to the penetration of the non-programmable renewable energy sources;
to evolution of the market coupling project in Europe;
the Cross-Border Redispatch Cost-Sharing problem among different Countries.
The practical (numerical) lessons of the course will allow the students to (DdD2, DdD4):
understand how it is possible to implement (from a mathematical point of view) an electricity market model;
apply the optimization theory and algorithms for modelling electricity markets;
Finally, the simulation of the pool market will allow the students to apply the theoretical knowledge to understand which are the factors that affect the strategic behavior of the market player in the day ahead electricity market section (DdD2).

Modalità di valutazione
After the end of the course, students participate to one of the available final examinations that consists on an oral test.
The oral part generally consists in 2 or 3 questions on all the topics covered by the course, including the subject of the practical (numerical) lessons.
Students should demonstrate full comprehension of the subjects and the usage of the appropriate technical language (DdD1, DdD2 and DdD4).
