DESCRIPTION - summary of the module content

This module has been designed to develop the candidate knowledge in Power Electronics and Power Systems. The future grid will see more integration of Renewable Energy Sources (RES) and thus it is vital to understand Power electronics which is the enabling technology for integrating RES to the Grid. This module is essential for Renewable Energy students. The completion of the second year Electrical module (CSM2044) is a prerequisite.

AIMS - intentions of the module

The objective of this module is to consolidate and further develop candidates’ core knowledge and understanding of electrical power systems engineering, particularly the issues associated with the connection of renewable energy projects to electricity distribution grids. The overall expected level of attainment is a capability to conduct sensible dialogue with specialist electrical engineers that have been commissioned to complete grid connection studies. Economic, legal and regulatory factors, which influence the design and operation of electricity transmission and distribution networks, are also covered.

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

Module Specific Skills and Knowledge:

1. Knowledge and understanding of data requirements and the mathematical pre-processing methods that should be adopted in order to conduct calculations to simulate or analyse the performance of electrical transmission and distribution networks.

2. Familiarity with the technical terms relevant to the operation, management, policy and regulatory aspects of a typical electricity supply industry.

3. Good understanding of the underlying physics relevant to the operation and stability of an electricity network.

4. Understanding of the different factors to be taken into account, and an appreciation of potential problems that might present, in managing a transmission or distribution network, including load factors, balancing load and generation, control of network voltage and frequency, reactive power requirements etc. This should be done through the tutorials, coursework and the use of the supporting computer software i.e. PowerFactory/DIgSILENT toward completion of the design assignment.

5. Good understanding of the level of losses inherent in the operation of an electrical network, their particular causes and potential approaches to their reduction, particularly the role of distributed generation. This should be done through the tutorials, coursework and the use of the supporting computer software i.e. PowerFactory/DIgSILENT toward completion of the design assignment and the successful completion of simulation practical.

6. An understanding of regulatory impacts on decisions relating to network integration, maintenance and development, with particular regard to economic implications and incentives for companies in monopoly and competitive sectors.

7. Basic capability to use electrical network simulation software to conduct simple grid connection studies for complex wind (familiar context) and wave power projects (unfamiliar contexts), evident through completion of the design assignment.

8. Ability to specify (generate) and interpret (analyse) grid connection studies for renewable energy plant conducted by third parties, evident in the design assignment report.

Discipline Specific Skills and Knowledge:

9. Candidates should demonstrate, good understanding of the capabilities of mathematical and computer methods for solving electrical network distribution problems and be capable of assessing the limitations of such software in complex renewable energy project development.

10. Candidates should be capable of identifying inconsistencies and misleading impressions from data and the sufficiency and appropriateness of data for analysis. This should be evident in the design assessment report.

Personal and Key Transferable/ Employment Skills and  Knowledge:

11. Candidates should demonstrate in writing their ability to make effective use of resources provided and to locate further resources to be needed to supplement their study. This should be evident in the design assessment report.

12. Candidates should be able to demonstrate understanding of the functionality of an electrical network simulation package (PowerFactory/DlgSILENT). This should be evident through the successful submission of the design assignment.
