10. Course Goals (acquired competencies): Proficiency in the theory of reliability, reliability indices and the methods for analyzing the reliability of systems. Mastering, understanding and applying the basic concepts and principles of reliability assessment of different segments of the power system (generation, transmission and distribution), as well as the whole power system considered integrally. Gaining ability to find the most effective measures and techniques to increase the reliability of the power system.
11. Course Syllabus: Concept of systems reliability. Non-repairable systems – characteristic functions and indicators. Determination of reliability indices based on data from the exploitation of system elements. Characteristic probability distributions. Repairable systems – state diagrams and indices. Exponential distribution of the time of normal operation and recovery. Complex systems that can be described by Markov processes. Stationary indices of system reliability. Reliability graphs – elementary network structures, complex networks. Minimal cuts. Minimal paths. Complex systems – fault tree analysis, search of states. Monte Carlo simulation method.
Models of the generators in power systems – two-state model, group of generators, peaking power plants. Generators’ reliability indices. Available generation power in the system. Consumption model. Analysis of the generation system reliability – deterministic procedures and Monte Carlo Simulation. Reliability of the electricity distribution system – specifics of the distribution systems, fault location and repair. Calculation of the reliability indices of distribution systems. Calculation of the reliability of the electricity transmission system. Transmission system reliability indices. Interconnected power systems. Restrictions on energy exchange. Integral power systems. Analysis of the structure of the power system. Simultaneous outages. System performance analysis and calculation of reliability indices. Technical-economic analysis. Loss due to power outages. Choosing the most favorable solution.
12. Learning methods: Teaching the theoretical part of the course, exercises on practical examples, interactivity on classes, consultations and homework/project assignments.

19. Conditions for acquiring teacher’s signature and for taking final exam Regular attendance at lectures and exercises
20. Forms of assessment During the semester, there are two mid/end-term partial exams (120 min each). Besides these exams, any student must complete and submit the required homework/project assignments, according to the schedule published at the course web site. For the students that will not be successful at the partial exams there is additional opportunity to do final exam (180 min.).
The final mark is determined from the weighted average of scores from the exams and homework/project assignments.
During the exams, it is not allowed to use any literature in printed or electronic form. Calculators are allowed, but not mobile phones, tablets or similar electronic devices.
