This course will address SDG (Sustainable Development Goal) No. 7: Ensure access to affordable, reliable, sustainable, and modern energy, taking into account:

Improvement of energy efficiency. Increase international cooperation to facilitate access to clean energy research and technology, including renewable sources, energy efficiency, and advanced technologies.

The activities to be carried out in the development of the course are as follows:

Large-group expository classes (A1): These will involve explaining the content of each topic using multimedia tools (methodology M1). After explaining the content, problem-solving and practical cases will be developed (methodology M1), and students will be encouraged to solve problems and real-life cases based on the explained content (methodology M5 based on projects, PBL).

Small-group classes (A2): Two-hour sessions will be conducted, starting with laboratory practices (methodologies M6 and M9) and then simulating those practices using Matlab and Simscape in the computer lab (methodology M7). In these small groups, exercises proposed in each practice guide will be solved to verify the feasibility of the work done (methodology M11), taking into account project-based learning (PBL).

Collective/individual tutorials (A3): These sessions will be held at the end of each topic to clarify doubts (methodology M17), supervise and discuss the proposed projects from activity A1 individually or collectively (methodologies M14 and M18), and allow students to explain their work for a brief period of time (methodology M19). Finally, seminars will be held for topics that pose greater difficulty in learning (methodology M15).

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support

According to Article 13 "Evaluation Procedures" of the Academic Regime and Evaluation Regulations of the University of Jaén, the evaluation of this course will be generally conducted through a comprehensive procedure, where students are assessed based on assignments, attendance, practical work, and exams.

The evaluation system will consist of the following items:

Active participation in class (S1): This includes attendance to various planned activities, active participation in class, and individual and/or group activities. This aspect will account for 15% of the overall grade for the course. Competencies CB2, CB3, CB4, and learning outcomes 30, 31, 32, and 33 will be assessed through this aspect.

Mastery of theoretical and operational knowledge of the subject (S2): This involves a written exam composed of two distinct parts. The first part will include an appropriate number of theoretical-practical questions, and the second part will consist of several problems aimed at assessing the student's acquisition of knowledge developed in the course objectives. This aspect will account for 70% of the overall grade for the course. Competencies CB2, CB3, CB4, CB5, CEL1, CEL2, CEL4, CT2, and learning outcomes 30, 31, 32, and 33 will be assessed through this aspect.

Practical work, assignments, practical cases, and problems (S3): This includes laboratory work, lab reports, assignments, solving proposed cases and problems related to the course topics. These works will be analyzed based on structure, quality of documentation, originality, spelling, and presentation. This aspect will account for 15% of the overall grade for the course. Competencies CB2, CB3, CB4, CB5, CEL1, CEL2, CEL4, CT2, CT4, and learning outcomes 29, 30, 31, 32, and 33 will be assessed through this aspect.

To pass the course, it will be necessary to obtain a minimum grade of 4.5 out of 10 on the written exam.

Attendance to practical sessions and submission of lab reports, assignments, cases, and exercises is mandatory to pass the course.

Students may request a change in the evaluation procedure to a single-test format when unforeseen circumstances arise.

In the case of a multimodal/mixed scenario, the following considerations will be taken into account:

• Depending on the anticipated number of students and the limited capacity of the classroom and laboratory, both theoretical and practical classes will be held 100% in-person, with the possibility of implementing small group rotations for practical classes.
• Some tutoring sessions will be conducted in-person, while others will be conducted online (synchronous and asynchronous). Online tutoring sessions will take place through the Google Meet platform.
• In any case, the evaluation system of the in-person scenario will be respected.
• The exam will be conducted in-person.

2- EVALUATION SYSTEM

Ordinary and Extraordinary Exam Sessions

To pass the subject, it will be necessary to achieve a minimum grade of 4.5 out of 10 on the written exam.

Attendance to practical sessions and submission of practice reports, assignments, cases, and exercises is mandatory in order to pass the subject.

3- RESOURCES

In addition to the resources planned for the in-person scenario, email, resources from the PLATEA platform, Google Meet, other similar platform resources, as well as the technical means provided by the University will be utilized.

In the case of a non-face-to-face scenario, the following modifications will be implemented compared to the face-to-face scenario:

• Classes will be delivered online synchronously, following the established schedule. The platform used for the classes will be Google Meet.
• Tutorials will be conducted entirely online and can be individual or group sessions. The scheduled hours will be respected, and appointments can be arranged with the professor in advance. Tutorials will take place through the Google Meet platform.
• Oral presentations will be conducted virtually, using the Google Meet platform.
• The exam will be conducted online through platforms such as Google Meet, Google Form, PLATEA resources, and similar platforms. The exam will consist of a series of practical exercises that students will complete independently, following the established procedure for this type of assessment. Additionally, it may include a theoretical test that can be written, in the form of an online multiple-choice test recommended by the platform, or an individual oral presentation on one or more theoretical topics.
• Laboratory practical sessions will be replaced by online classes where simulations will be conducted using specialized software, ensuring that students' workload and competencies are not compromised.
