• Title
Power system analysis on IEEE 14-Bus System
• Application
The IEEE 14 Bus Test Case represents a portion of the American Electric Power System (in the Midwestern US) as of February, 1962. IEEE 14 bus system is widely used as a case for conducting various studies like short circuit analysis, load flow studies, and interconnected grid problems.

○ System specifications
• 14 bus system
• 5 machines
• 11 loads
• 5 transformers
• 1 shunt compensator
For more information, please check the DigSilent model (available in iLearn).
• Project aim
The aim of this project is to perform analysis on IEEE 14-Bus System given in Fig. 1.
• Project objectives
○ Identify the specification of the given IEEE 14-Bus System (e.g. total generation, total load, total loss, bus types, line types, load models, voltage profile, stability region, etc)
○ Among the available cable options in the library of the project for the line 1-2 (2 options), and line 6- 13 (4 options), select the two options (1 for each line), so that the network faces the least violence during future outages
○ Identify the most reliable bus at which a 50-MW EV charging station can be connected. Provide a report and include your recommendations to make the system more reliable
○ Perform fault analysis (i.e., three phase) on at least one line on your choice and design a protection relay system to successfully isolate the fault. Recommend and implement solution(s) if the designed relay is faulty and cannot operate. Discuss if any other protection equipment can be offered?
• Design specifications
The result of the analysis should meet the following requirements:
○ Voltages of the buses to be within ±5% of the reference voltage (the slack bus voltage)
○ All the equipment do not overload (or minimum violence) at any time including n-1 outages
○ Power factors at the buses to be higher than 0.85
○ At any time, the total generation is equivalent to the load demand plus losses
• Assessment
This team project contributes 50% to your final mark. The assessment for this project consists of:
○ Individual and team assessment
▪ Oral presentation and demonstration of the project 20% (Week 14 - Wed)
▪ Individual project logbook 10% (end of Week 13)
▪ Peer assessment regarding the actual contribution of each team member (Week 13)
▪ Project report to be submitted in iLearn by each team member 20% (end of Week 13)
• Learning outcomes
This project will contribute to the following learning outcomes:
○ Power system modelling, load flow studies, fault studies, power system stability, and power system planning
○ Simulation of power networks using DigSilent Power Factory
○ Collaborative work in teams and pear learning
○ Communication of technical concepts and results in written reports
