The Master’s course:

The main goal of the Master’s Degree in “Electrical Energy Conversion and Power Systems” (EECPS Master) is the training of qualified staff in areas related to electrical energy management, emphasizing in power systems for renewable energies. The Master presents a double approach: scientific and professional. In the scientific thread, training focuses on the design of two main applications: Electrical Power Systems and Electrical and Hybrid Traction Systems. On the other hand, in the professional thread, training is focused on the management of electrical energy. Thus, the subjects of this thread have been designed attending to two main issues, such as the management of energy in large consumers and the generation and transmission of electrical energy in a liberalized market. Three main lines have been considered as keystones in the Master:

• Electrical Power Systems
• Electrical and Hybrid Vehicles
• Energy Efficiency and Renewable Energies

The second semester:

The second term offers several compulsory courses for all the students. These subjects will promote the acquisition of the common skills of the Master. This term includes a subject called "Lab", designed to develop and build a functional experimental prototype based on the theoretical knowledge acquired during the first two semesters. The work done in this subject will serve as a starting point for the Master’s Thesis.

The subject:

This subject integrates different skills gained or reviewed in the previous term, and includes contents on advanced power electronics, generation and transmission systems, power plants, control and modeling. The basic aim is to understand the operation of power electronic circuits used in renewable power systems. Also the instrumentation, measuring and telemetry subsystems are discussed.

The subject is included in the second module of the master, called “common technologies”

The students must certify that they have passed basic skills and competences in power electronics, power plants, electric machines and control systems and automation. This can be either accomplished at his/her incoming student profile and CV or, if not covered there, by passing the related subjects of the first semester.

Learning methodology:

The learning methodologies used are lectures, resolution of exercises and problems, problem based learning and Project oriented learning.

The subject accounts for 6 ECTS, being 5 of them given by teachers from the University of Oviedo and the ECTS left by external teachers.

This ECTS will be given by external faculty as lectures and seminars (7.5 hours per ECTS), while the ECTS given by the staff from the University of Oviedo will address lectures, class practice and seminars, laboratory practice and group tutoring.

The faculty will propose exercises and problems and projects, that will account for the non-presential working hours (105 hours per student).

The evaluation and assessment of the skills gained will be carried out considering the full contents of the subject, as well as written and oral tests at the end of the semester.

Exceptionally, in the event that health conditions require it, non-attendance teaching activities may be included. In this case, students will be informed of the changes made.

These are the percentages of the final qualification of the different evaluation systems used in the subject:

The final student’s qualification will be obtained as follows.

• The 40% of the student’s mark comes from the assessment of the proposed works / projects. It is a mandatory test.
• Another 10% will come from the proposed simulations developed by the student, considered as a simulated task performance test. It is a mandatory test.
• Another 25% comes from an individual written test, which will be done at the end of the semester. This test will be comprehensive covering all topics discussed. Taking the final exam is mandatory, and a minimum score of 4/10 must be achieved.
• A 15% will come from oral tests on the topics developed by the students.
• Finally, the 10% left comes from the attendance to the presential hours (a minimum of 80% is required).

Exceptionally, in the event that health conditions require it, non-presential evaluation methods may be included. In this case, the student body will be informed of the changes made.
