Smart Grids

Semester 2 · 45550 · Master in Energy Engineering · 6CP · EN

The course and develops mainly the subjects of the operation and regulation of the national grid high voltage.
After outlining the international framework of regulatory boards (CEN, CENELEC, ETSI, IEC, UCTE, etc ...), it introduces the equations of three-phase lines with the propagation constant and the characteristic impedance.
It will explain then technological innovation on electric transmission and distribution, as well as the control system in real time. It will be explained the mechanisms to control voltage and frequency according to the request of reactive and active power. It will also expose the criteria for the protection of the transmission lines and moreover the problem of power quality and the characteristics of the free market.

Propaedeutic courses
The Smart Grids Course is strictly related to the Electrical Systems Engineering course.

Teaching format
Frontal lectures and seminars.

Educational objectives
At the end of the course, students will have the following skills: 1. Knowledge and understanding: Understand the operation and design MV and HV AC power supply lines; 2. Applying knowledge and understanding: Being able to participate in the management of an electrical transmission network for controlling the frequency and voltage of the network; 3. Making judgements: Knowing how to judge, identify and resolve anomalies and failure conditions of the electricity transmission grids; 4. Communication skills: Interact with other operators and technicians to operate in the free energy market; 5. Ability to learn: Learn and develop new high voltage line protection systems.

Assessment
The evaluation of students' training will take place with an oral test as summative assessment, during which the degree of learning (ILO 1) and the ability to manage a transmission network (ILOs 2 and 3) will be assessed, together with their communication skills (ILO 4).

Evaluation criteria
The preparation of the students will be assessed based on the degree of: • technical preparation of the topics covered; • learning of the operating and management methods of the electricity distribution and transmission networks; • ability to evaluate fault conditions and recovery methods.

Required readings

PowerPoint presentations will be available in the course reserve collection database.
