Objectives
The course aims to develop students’ interest in and knowledge and understanding of tools and methods for system reliability at the substation and plant level and electricity generation methods. The module addresses in depth reliability models, risk analysis and compromise seeking among several planning objectives, namely investment, security, quality of service and generation and substation technology .
Learning Outcomes:
Students will develop knowledge and understanding of:
-undamental concepts, principles and mathematical theories used for decision in an environment contaminated with uncertainty
-methods to evaluate indices to study the goodness or acceptability of decisions
-undamental concepts and principles of risk analysis and system reliability
- power generation (hydro, thermal and renewable)
- substation design
They will acquire intellectual and practical skills to:
- develop appropriate models of scenario building and criteria representation for system planning
- evaluate decisions under the paradigm of risk analysis
- use multiple criteria concepts in evaluating solutions
- write a technical report based on performed studies
