Module summary

The teaching and assessment methods shown below will be kept under review during 2021-22. In particular, if conditions allow for alternative formats of delivery, we may amend the timetable and schedule appropriate classes in addition to (or in place of) any online activities/sessions. Where learning activities are scheduled to take place on campus, it may be possible and/or necessary for some students to join these sessions remotely. Some of the listed contact hours may also be optional surgeries. Students will be provided with full information about the arrangements for all of these activities by the module staff at the beginning of the teaching semester.‘Independent online learning’ may involve watching pre-recorded lecture material or screen-casts, engaging in learning activities such as online worked examples or mini-projects, etc. Students will be expected to fully engage with all of these activities. The time commitment for independent online learning, and also the frequency and duration of online sessions are approximate and intended as a guide only. Further details will be confirmed when the module commences.Where assessments are shown as Online Time-Limited Assessments, the durations shown are indicative only. The actual time permitted for individual assessments will be confirmed prior to the assessments taking place.


This module covers fundamentals of power system modelling, analysis and operation. Students gain an understanding of the various layers and components in modern power networks and how power systems are operated. The module also provides an opportunity to learn relevant programming tools (DIgSILENT PowerFactory) to model, design and analyse power systems.

Learning outcomes
On completion of this module students should be able to:

1. Explain the operation and functional models of the main components in a power system.
2. Use phasor representations to analyse complex AC power systems and perform calculations to determine real, reactive and apparent power.
3. Apply mathematical and computational methods to solve the load flow calculations for power systems.
4. Describe the principles of planning and operation of power systems.
5. Discuss, through case studies, the technical challenges in both the design and the operation of power systems, and the future trends in power systems and smart grids.


Topics may include, but are not limited to:

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

Private study

Students are expected to use private study time to consolidate their understanding of course materials, to undertake preparatory work for seminars, workshops, tutorials, examples classes and practical classes, and also to prepare for in-course and summative assessments.

Opportunities for Formative Feedback

Students studying ELEC modules will receive formative feedback in a variety of ways, including the use of self-test quizzes on Minerva, practice questions/worked examples and (where appropriate) through verbal interaction with teaching staff and/or post-graduate demonstrators.

.Resits for ELEC and XJEL modules are subject to the School's Resit Policy and the Code of Practice on Assessment (CoPA), which are available on Minerva. Students should be aware that, for some modules, a resit may only be conducted on an internal basis (with tuition) in the next academic session.
