The syllabus of the course aims to familiarize students with the advanced concepts of electrical power systems, components and numerical methods in power systems, the functional characteristics of electrical power systems and the analysis and models of the main components of power systems.

It also refers to optimization and economic concepts for operation of interconnected power systems, so that the student will acquire an overall understanding of the procedures and methodologies to analyze and solve an electrical power circuit. Finally, the aim of the course is the advanced understanding of the importance of the electrical power systems in the modern economy.

Upon successful completion of this course the student will be able to:

• understand features of advanced power systems, such protection and reliability and their relationship to the overall production, transmission and distribution of electricity.
• use advanced tools and techniques for solving load flow and power circuits
• analyze and calculate the elements of a power system including economic operation, optimization and load distribution.
• collaborate with his fellow students to create and present a team project in a study of optimum power system which includes the technical and economical analysis, distribution system load flow, stability, and advanced mathematical models of the system.
