IEEE Guide for ULFS

Information on the application of underfrequency load shedding and restoration to ac power systems is compiled in this guide. Various system conditions that may require the use of underfrequency load shedding and the application of protective relays to various methods of performing underfrequency load shedding are described inthis guide. Some practical examples of underfrequency load shedding applications are also provided.

Robust Power System Frequency Control

Frequency control as a major function of automatic generation control is one of the important control problems in electric power system design and operation, and is becoming more significant today due to the increasing size, changing structure, emerging new uncertainties, environmental constraints, and the complexity of power systems. Robust Power System Frequency Control uses the recent development of linear robust control theory to provide practical, systematic, fast, and flexible algorithms for the tuning of power system load-frequency controllers.
