87236 - Electric Power Systems M

Academic Year 2021/2022

Learning outcomes

The course provides the basics for understanding the main aspects of modern power systems/smart grids analysis and operation in steady state and transient/dynamic conditions. At the end of the course students are able to understand the main technical problems relevant to transmission and distribution of electric energy, and can solve them with particular reference to load flow, short circuit calculation, stability, frequency control, voltage control and renewable sources diffusion in the electric network and smart grids.

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.
  • Insulation coordination.
  • Protections in transmission systems.
  • Interaction between electromagnetic transients and electromechanical transients.

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.
