Module aims

This module aims to present the current (advanced) technologies and trends in development that will shape future electrical power systems. The students will gain a comprehensive knowledge and understanding of the construction, operation and control principles of power systems. They will learn advanced analytical skills for examining different modes of operation in complex systems. The content includes the following main elements:

  • Generation, Transmission and Distribution of Electrical Power
  • Balanced and Unbalanced 3-Phase Systems
  • Load Flow Analyses
  • Fault and Stability Analyses of Power Systems
  • Power System Protection Concepts and Techniques
  • Operational Security Control
  • Benefits and Limitations of Wide Area Measurement (WAM)
  • Effects and Management of Distributed Generation
  • Flexible AC Transmission Systems (FACTS) and High Voltage DC
    (HVDC) Transmission Technologies
  • Power Quality Monitoring and Management
  • Renewable Power Penetration and Grid Code Requirements
  • The Role of Energy Storage and the Development of Relevant
  • Smart Grids: Communications and standards, demand side response, wide area measurements, privacy and cyber security.

Assessment group D3
Weighting Study time
Assignment 1: Voltage Control Philosophy of an Industrial Power System 30% 20 hours

Understand the evolution of an industrial power system and the need to conducting design studies. Through the exercise, the students will get some hand on experience about load flow, stability and fault level analysis of power systems, and develop knowledge of techniques to control them.

Assignment 2: Renewable Generation and Grid Impacts 30% 20 hours

The students will enhance their knowledge about renewable generation systems and their impacts on the grid. Simulation will be conducted to show the characteristics of the renewable systems, leading to analyses on the modern technologies to manage such impacts.
