Module goal - Knowledge and skill to be achieved by students
  The goal of this course is to provide students with solid basic understanding in following areas:
<br>
Static and transient power system stability; methods and resources for improvement of power system stability; basic principles of power system protection; control and protection of power systems; generation and absorption of reactive power; methods for control of voltage conditions; FACTS devices and their applications; DC transmission systems.
<br>
Upon completion of this course students will be able to analyze certain states and regimes of complex power systems operation. By using modern software tools, a student will be able to pursue appropriate projects.
<br>

Syllabus
  Static and transient power system stability; modeling of synchronous generators ; dynamics of rotor and the swing equation; equal-area criterion of stability; Numerical solving of rotor dynamics; multi-machine stability studies; voltage stability, radial systems, criterions of voltage stability;
<br>
automatic voltage regulators; computer modeling and programs; methods and resources for improvement of power system stability.
<br>
Basic principles of power system protection; protection relays; concept of protection zones; primary and secondary protection; principles for coordination of overcurrent protection; protection of generators, transformers, motors, busbars, lines and cables; differential protection; elements of distant protection; digital relays; system for auto reclosing; communication systems; protection and control integration.
<br>
Generation and absorption of reactive power; voltage-control mechanisms; shunt and serial static compensators; FACTS devices and their applications.
<br>
DC transmission systems; comparisons with AC transmission systems; converter switchgears; overhead lines for DC transmission systems; control and protection in DC transmission system.

Didactic methods
  Course lessons are taught by the professor in lecture halls, and followed by demonstration and solving of practical examples and mathematical equations/graphs. Additionally, students spend time on tutorials and lab-exercises. They resolve specific problems pertaining to their theses, using available or student-developed software. Goal of these activities is to enable students to get hands-on, practical experience in this area, as well as to gauge students' knowledge through assigned papers and exams (mid-term, as well as final).
<br>

Exams
  During the course students earn points according to the following system:
<br>
- Attending classes and tutorials: 10 points; a student with more than three absences from lectures and/or tutorials will not be eligible to get these points.
<br>
- Home assignments, laboratory reports and/or final thesis: maximum of 10 points.
<br>
- Mid-term and final exams: a student can score up to 20 points on each exam (passing grade is 10 points).
<br>
During each of the two exams (time assigned is 90 minutes) students will solve simple questions – designed to examine whether students acquired basic theoretical knowledge –multiple choice problems, as well as one open-answer problem. Students who gain less than 20 points during one semester must re-take that course.
<br>
Students who earn 40 or more points during the semester are eligible for taking a final exam; the exam asks the student to discuss mathematical problems from the mid-term exam and home assignments, as well as to answer to simple questions related to general course topics.
<br>
A student can score a maximum of 40 points on the final oral exam (passing threshold is 20 points). A student who gets less than this minimum, must take a makeup oral exam.
<br>
A student who earns 20 points or more, and less than 40 points during the whole semester will have to take a makeup exam. The makeup exam is organized in the following manner:
<br>
- Written part is structured similarly to mid-term written exam, during which students will have to solve problems in which they failed on their mid-term exams (got less than 10 points).
<br>
- Oral part of the exam is structured in the same way as the oral part of the final exam.
