IEEE Transactions on Power Systems Vol. 28, nº. 2, pp. 1779 - 1786

Summary:

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.
