A new Approach for Load shedding scheme

Depending on the power system condition in terms of operating reserves, and equipment availability, the severity of the disturbance may cause parts of the power system to be islanded, or to lose synchronism and enter a complete blackout. The aim of this paper is to design an automatic under frequency load shedding scheme which can be able to safeguard the power system against major disturbance involving multiple contingency events. The proposed load shedding scheme is tested on a real model of network. The simulations were performed on a dynamic model of the power system using the software package SICRE.
