Summary

Already in 1978, Fink and Carlsen pointed out that in situations with the power system in emergency state it is “Time for Heroic Actions”. Nowadays, with the growing complexity of the electricity system and with its increasing uncertainty challenging grid planners and operators, also the task of connecting more customers and renewable energy sources while ensuring a secure operation could provide a wish for heroic superpowers. Having System

Integrity Protection Schemes (SIPS) that protect the power system from known and unknown threats and help to maintain a reliable electricity system, enables the grid operators to sleep better at night. With its story not often told, although it might have protected us from sever problems or enabled a better future, this unknown superhero of the power system helps make the world a safer place - as all good superheroes do!

In this paper, we will unveil the mysteries around SIPS, and how SIPS influence the common reliability criteria in operation and planning of the power system. The paper presents part of the work performed by the CIGRE Joint Working Group C2/B5.46 “System Integrity

Protection Schemes and the (N-1) criterion”.
