Principles of a centralized UFLS scheme for small isolated power systems

L. Sigrist, I. Egido, L. Rouco

This paper presents the principles of a centralized underfrequency load-shedding (UFLS) scheme based on a frequency stability boundary curve suitable for small isolated power systems. The centralized UFLS scheme is illustrated in case of two small isolated Spanish power systems.


Keywords: Frequency stability, load shedding, power system protection.
