 SHE Level 5 SCQF Credit Points 15.00 ECTS Credit Points 7.50 Module Code MMH624490 Module Leader Dong Chen School School of Computing, Engineering and Built Environment Subject Electrical Power Engineering Trimester B (January start)

### Summary of Content

The module aims to equip the students with the knowledge and skills required for the design and analysis of hybrid modern AC/DC power systems. Modern and future power systems will witness a growing penetration of power electronics converters in the system design. This module develops the students' understanding of FACTS (Flexible AC Transmission Systems), HVDC and other emerging power electronics applications for power systems and puts emphasis on the skills required to analyse and design such systems. -3

### Syllabus

The taught syllabus covers the following areas: Principles and implementation of FACTS devices. Principles and implementation of HVDC technologies. Principles and operation of hybrid AC/DC transmission system. Modelling and control of VSCs in power systems: -Phasor, average and detailed models. -2-level VSC. - Modular Multi-level Converter. - Voltage reference frame control, Phase Locked Loop (PLL), current control, voltage control. Principles and implementation of emerging hybrid AC/DC distribution networks: AC/DC microgrids, active distribution power systems

### Learning Outcomes

On successful completion of this module the student should be able to: 1. Show a detailed knowledge and understanding of modern FACTS devices.2. Use appropriate mathematical and computer modelling techniques to analyse typical FACTS devices.3. Assess and analyse emerging power system configurations: hybrid AC/DC power networks.4. Use appropriate mathematical and computer modelling techniques to analyse typical power systems with Voltage Source Converter (VSC) control structures.5. Find and apply relevant standards, for example, IEC 61975 and IEEE 1547.

### Teaching / Learning Strategy

The module material will be introduced through lectures, while practical exercises, based on the lecture material, will be given to students for their practical sessions. Tutorials will be used to help explain and elaborate on both the lecture material and the practical exercises and provide opportunities for tutor led formative feedback to students. This is detailed as follows; -360b7 A policy of providing staff access to students; a programme and library induction pack and supporting tour; a module handbook providing detailed information. -360b7 Support of a module leader and programme leader, in addition to student representatives. These representatives reflect students' views and concerns at staff-student liaison committee meetings and programme committee meetings. -360b7 Underpinning support is provided from central university support services including: online study skills facility, student counselling service, access to the Learning Development Centre, IT support using e-mail and/or on-line resources). -360b7 Development of knowledge and skills, and the use of tools, techniques and methods which are immediately useful to employers, both in the UK and overseas. -360b7 Strong emphasis in the module on industrial or research projects including the use of visiting lecturers and industrial visits. b7 The module is designed with a very strong professional emphasis taken from the industrial expertise of staff, the industrial liaison committees and the professional body requirements. This will enhance the career opportunities of the students in industry. b7 The lecture delivery will be enhanced by a variety of genre including, where appropriate, videos, computer based models and other multimedia approaches b7 On line learning materials are available electronically. Discussion boards will be used to encourage teacher and peer-to-peer dialogue on certain topic areas where this form of communication would be regarded as effective. b7 Academic staff and the Learning Technologists will continue to work together to develop and operate the module on GCU Learn to ensure student support and information sharing. b7 Students are provided with formative and summative feedback via a variety of mechanisms. Feedback on coursework is provided within 3 working weeks of submission providing information on strengths, weaknesses and suggestions for corrective action. b7 Student feedback on teaching, learning and assessment will be sought at the end of the semester through a module evaluation questionnaire. Full time -359d8 This module will be taught in a three-week block. During the first week the lecture material will be accompanied by by industrial case studies. During the two remaining weeks students will undertake tutorials and practical work, and will complete the assessment. The module will be guided by tutors and supported by the managed learning environment. All teaching and learning materials will be available on GCU Learn. Part time -359d8 Students will attend the first week of the module where materials will be delivered by lectures accompanied by industrial case studies. Students will complete the remaining material off campus, supported by learning materials and course tutors. The module tutors can be contacted via e-mail, telephone and GCU Learn/discussion board. All teaching materials and case studies will be available on GCU Learn. Distance learning A study pack will be provided including: a study guide, lecture notes, tutorial notes, case studies and worked examples. All material will also be available on GCU Learn. Module tutors can be contacted via e-mail, telephone/skype and GCU Learn through discussion board.-3 -357
