KD6010 Assessment Brief

Instructions on Assessment:

• Using the Simscape®/Matlab® software package, construct the example network shown in Figure 1.Throughout this work, refer to the Simscape® User Guide [1], maintain a logbook to record your progress,and save all simulation results. 

Figure 1. A single-line diagram of the power network.

• This isindividual assignment.Each student must submit a report of no more than 20 pages (includingdiagrams, table of contents, and references). The report should include computer printouts and responsesto the specified tasks. While you may collaborate on developing the network model, the report must beyour own original work. Copying from peers constitutes academic misconduct (see the respective sectionat the end of this document).All sources must be properly acknowledged and cited.
• Submit the report (including the results of the network modelling) via Turnitin on the module E-LearningPortal no later than 23:59 on Friday 23rd January 2026.
• Email all simulation files for the network model to zhiwei.gao@northumbria.ac.uk. Group them in a singlefolder and clearly label it with your name and the module code/title. Note: only the coursework submittedvia the official route will be marked; the e-mailed files are for verification/checking purposes only.

Mapping to Programme Goals and Objectives

The aims of this coursework are to:

• Gain an understanding of how software packages are used for power system modelling, including diagram (dynamic model) development, load flow analysis, balanced and unbalanced fault analysis, power system protection, and state and transient stability studies.
• Design power protection relays, harmonic filters, and load-sharing strategies for cost minimisation, supported by simulation-based validation.
• Enhance learning by linking theory and analytical methods to computer-aided techniques for system analysis and problem solving.

Learning Outcomes (LOs):

• LO1: Critically understand power systems theory and techniques associated with operation, design, simulation, and analysis. (AHEP4: C1)
• LO2: Formulate numerical methods and principles for power system design and analysis, and perform fault-level calculations and/or transient stability studies. (AHEP4: C2, C4)
• LO3: Critically analyse control of power systems with respect to active and reactive power, voltage levels, economic load dispatching, and stability. (AHEP4: C2, C4)
• LO4: Analyse disturbances in power systems and their effects on quality of supply and stability, recommending appropriate design solutions. (AHEP4: C4, C5, M5)
