Modern Aspects of Power System Frequency Stability and Control

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.

• 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
