Modern Aspects of Power System Frequency Stability and Control
1st Edition
Description
Modern Aspects of Power System Frequency Stability and Control describes recently-developed tools, analyses, developments and new approaches in power system frequency, stability and control, filling a gap that, until the last few years, has been unavailable to power system engineers.
Key Features
- Deals with specific practical issues relating to power system frequency, control and stability
- Focuses on low-inertia and smart grid systems
- Describes the fundamental processes by which the frequency response requirements of power systems in daily operation are calculated, together with a description of the actual means of calculation of these requirements
Readership
Control and communication engineers, power engineers, undergraduate and postgraduate engineering students

About the Author
Andrew Dixon
Dr Andrew Dixon holds a Doctor’s Degree in Applied Mathematics from the University of St Andrews, Scotland, and a Master’s Degree in Electrical Power Systems Engineering with Distinction from the University of Bath, England. He joined the National Grid Company in 1990, working in a range of technical roles in various parts of the company. From 2010 – 2015 he was instrumental in writing and developing new tools for the National Control Centre, Wokingham, UK to assist Control Engineers, to enable them to calculate Frequency Response Requirements for the National Grid system in Britain. These frequency response tools have been incorporated into a suite in the UK National Control Room and are used daily.
