DESCRIPTION - summary of the module content

Resilient electrical power systems are an essential part of the infrastructure essential for a modern society. This module will deepen your insights into steady-state power system operation and develop your skills in power system analysis. Hand calculations on a simple 3-bus power network will help you understand simulation-aided power flow calculation on a large interconnected power network. Emphasis  will be on the optimisation of the power system benefits in implementing economic dispatch and optimal power flow. An important aspect of this module is the delivery style, a mixture of theoretical and practical lectures and simulation-based laboratory exercises.

AIMS - intentions of the module

This module aims to develop your understanding of power system operation and its analysis from multiple core engineering perspectives. On successful completion of this module, you will attain the capability to calculate power flows in large power systems by iterative numerical approaches, be able to determine an optimal and economic dispatch of a power system and understand the criticalness of power system faults. This module will increase your confidence in performing an independent assessment of the steady-state operational conditions associated with a power system.
