Module summary

This module covers fundamentals of power system modelling, analysis and operation. The contents are deepened through lab exercises employing DIgSILENT PowerFactory.


This module gives students an understanding of the various layers and components in modern power networks and how power systems are operated. It provides the student with relevant programming tools (DIgSILENT PowerFactory) to model, design and analyse power systems.

Learning outcomes
On completion of this module, students should be able to:
- Explain the functioning and modelling of the main components in a power system;
- Be able to solve basic load flow calculations;
- Understand the principles of planning and operation of power systems;
- Have an overview of future trends in power systems and smart grids;
- Appreciate, through basic case studies, the technical challenges in both the design and the operation of power systems.


Power system concepts: single- and three-phase systems, phasor representation in sinusoidal steady-state, real and reactive power, per unit system.

Fundamentals and modelling of power system components: generators, loads, transformers, transmission lines, efficiency and power loss.

Power flow analysis: admittance matrix, power flow equations, Newton-Raphson method.
Fundamentals of power system operation and smart grid technologies.

Fundamentals of power system operation and smart grid technologies.
