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 third semester:

This subject belongs to the third semester (specialization stage). The third term has been designed according to two possible tracks: professional and research. This subject belongs to the second one. The scientific-research track approaches the technology development and the industrial design established in the specific competences of the master lines: "Power systems" and "Electric / Hybrid vehicle".

The subject:

This subject integrates different skills gained in the first and second terms including advanced contents for modeling, simulation and analysis of generation, transmission and distribution in power systems that can be applied to distributed generation.

The basic aim of the subject is to study the tendencies in the future electrical power systems that integrate distributed generation, as well as its technologies and modes of operation. The concepts of microgrids and smartgrids will be presented. It will be shown how to design micro-management systems, from both technical and economical points of view.

The students must certify that they have passed basic skills and competences in power generation, transmission and distribution systems, by passing the related subjects of the first and second semesters. Due to the fact that it is a subject of the specialization stage, the student should handle the concepts expressed in the common stage of the program (semester 2).

CG14  Concern for quality and achievement motivation

Specific Competences:

CE1     Understanding of the importance and the area of utilization of electrical power             systems          for generation, transmission and distribution of electrical energy.

CE2     Characterization and modeling of the main energy sources and electric power             loads

As it can be observed in the next table, the numbers of hours assigned to this course are divided in “in-class work” and “homework”. Among the “in-class work” hours are divided in lectures, seminars, laboratory, group tutoring and evaluation sessions. The teachers will use the lectures to present the theoretical basis of the subject. However, active learning methods such as “class discussions”, “think-pare-share”, “short written exercises“ or ”student debates” will be applied in order to keep an active attitude. Concepts stated in lectures must be applied to solve different types of problems or developing computer projects in seminars or computer lab hours respectively. The group tutoring sessions will be used to discuss about the theoretical concepts explained in lectures or their application seminars or computer lab.

These are the values for the evaluation of the students:

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

• The 35% of the student’s mark comes from the assessment of the proposed works / projects. It is a mandatory test.
• Another 20% will come from the proposed homework. It is a mandatory test.
• Another 30% 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.
• Finally 15% will come from presentation of the projects. It is a mandatory test.

DIFFERENTIATED ASSESSMENT: Each case will be studied and a compatible assessment will be proposed according to its specific conditions while observing University rules.
