Affordable and clean energy Sustainable cities

Academic Year 2019/2020

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) both for automation engineering students and for electrical energy engineering students.

  • 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

Oral closed-book final exam (exam schedules at https://almaesami.unibo.it). The spoken exam at the end of the course aims at assessing the achievement of the learning objectives. The final grade is defined on the basis of the partial grades reported in three specific questions on topics related to the contents of the course.

The achievement by the student of a complete knowledge of the course content and of its application to the solution of engineering problems, along with the use of the specific technical language, are assessed with marks of excellence. The mnemonic knowledge of the matter, with limited synthesis and analysis capabilities and a language not always appropriate bring to discrete evaluations. Learning gaps and / or inappropriate language justify negative assessments or low marks.
