RENEWABLE/CONVENTIONAL POWER GENERATION, TRANSMISSION AND HVDC/FACTS
Academic Year 2023/2024 - Teacher: Giuseppe Marco TINAExpected Learning Outcomes
The aim of the course is to give the students tools to be able to analyse and understand the
operating principles of the main components of a power system with specific attention to the inverter-based components as well the interactions among the parts when the power system is both in secure and alert operating conditions.
In particular, basic knowledge of the models of generators, transmission lines, loads and main power electronic devices will be provided as well as advanced knowledge of the principal regulations about voltage and frequency variables.
Knowledge and understanding
On successful completion of the module, the student will be able to:
Understand and apply the principles of the main components of a power system and power electronic converters used in transmission systems.
Select suitable characteristics of the main components of a power systems and frequency and voltage regulators in the generators.
Selection of the main active devices, analysis of the power converters and feedback loops.
The students will be able to solve practical design problems and produce technical reports.
Making judgements
Ability to properly evaluate the operating conditions of power systems in steady and transient conditions, considering also the variability introduced by the renewable nonprogrammable sources.
The students will be capable of properly evaluating the performance of various power converter topologies.
Communication skills
Ability to discuss with specialists’ interlocutors, issues related to the power generation from conventional and renewable power sources, analysis of modern power systems with the integration of inverter-based technologies.
Learning skills
On successful completion of the module, the student will be able to:
• identify the main quantities that characterize a power system.
• Calculate the electrical variables in an electrical network.
• know the equivalent models of the main components of a power system.
• Model an electrical network using the models and related parameters correctly.
• Describe the control of the network through the variables P, Q, V, and delta.
• Simulate and evaluate power flows.
• Analyze network conditions that can create problems of instability and insecurity.
Course Structure
Lecture organization
Lecturing is used to convey knowledge and it is organized as follows:
1) the lecture notes are outlined— first major points, then the minor points that elaborate on or explain each major point;
2) relevant, concrete examples, in advance of the lecture, selecting examples familiar and meaningful to the students are provided;
3) students are allowed to stop the lecture to ask relevant questions, make comments, or ask for review;
4) intersperse periodic summaries within the lecture.are considered;
5) lectures start with a question, problem, current event, or something that just grabs the students’ attention;
6) active learning techniques are used (technological aids, such as multimedia presentations);
7) simulations sessions are used to check and grasp the theoretical concepts.
Required Prerequisites
The students should have a working knowledge of:
1) ac three-phase electrical circuits,
2) trigonometry, basic calculus, complex numbers, and phasor concepts
Attendance of Lessons
The frequency of teaching shall not exceed 70% of the teaching hours, without prejudice to the provisions of Article 27 of the RDA and the Regulations on the recognition of the status of a working student, a sports student, a student in a difficult situation and a student with a disability
Students are encouraged to attend all class sessions as it is expected that the lectures, demonstrations and discussions will facilitate their learning.
