Course assessment

Conducting university questionnaires on teachers (student-teacher relationship, transparency of assessment criteria, motivation for teaching, teaching clarity, etc.). Conducting Faculty surveys on courses (upon passing the exam, student self-assessment of the adopted learning outcomes and student workload in relation to the number of ECTS credits allocated to activities and courses as a whole).

Overview of course assesment

Learning outcomes
Upon successful completion of the course, students will be able to:

1. categorise power system stability

2. understand and to apply electromagnetic phenomena calculation methods in power system transient states

3. interpret voltage stability criteria, modal and participation analysis

4. calculate power system characteristic variables in transient states, sketch P-V, Q-V curves and eigenvalue plot

5. make an adequate system model and perform simulations of different transient states

6. interpret the influence of AVR, turbine, governor, invertors, compensators and renewable energy sources on power system stabilityquencies
