87236 - Electric Power Systems M

Academic Year 2023/2024

Learning outcomes

The course provides the basics for the analysis of modern power systems/smart grids in steady state and transient/dynamic conditions. At the end of the course, students - know the main technical aspects of electric power transmission networks; - can carry out power flows calculations, fault analysis, assessment of angular, voltage, and frequency stability; - own the basic skills for the analysis of electromagnetic and electromechanical transients in electrical power systems, for the coordination of insulation and protections, and for the use of the EMTP computer code.

Course contents

The development of centralized as well as distributed clean electricity generation, the set up of electricity markets that foster competition and economic efficiency, and the expected electrification of the transportation system will make electricity the dominant energy form in the future. The course covers the key technical characteristics of the operation and control of modern electric power systems following the smart grid paradigm.

Course content:

Module 1 (6 CFU) 

  • Introduction to electric power systems.
  • Power flow analysis.
  • Fault analysis.
  • Power system dynamics and stability.
  • Angular stability.
  • Voltage stability.
  • Control of active power and frequency. Automatic generation control.

Module 2 (3 CFU) only for electrical energy engineering students.

  • Electromagnetic transients.
  • Protections in transmission systems.
  • Interaction between electromagnetic transients and electromechanical transients.
  • EMTP simulations of power systems in steady state and transient conditions.

Teaching methods

Traditional lecture.

Assessment methods

The exam consists of a closed-book test in eol.unibo.it, with a single mark. The test contains both theory and application calculations aimed at assessing the candidate's knowledge and operational ability in relation to the key concepts illustrated during the entire course (module 1 and module 2).

The achievement by the student of a complete knowledge of the course content and of its application to the solution of engineering problems are assessed with marks of excellence. The mnemonic knowledge of the matter, with limited synthesis and analysis capabilities, and difficulties in the application to case studies lead to discrete evaluations. Learning gaps and inability to apply the knowledge to case studies justify negative assessments or low marks.
