RSE proposes CIGRE's definition of resilience for power systems

RSE proposes CIGRE's definition of resilience for power systems

RSE team played a leading role in drawing up CIGRE's official publication


Over the last few years, RSE has extensively worked on developing the concept of power system resilience from a theoretical and experimental point of view.

See the monograph in the RSEview series:

http://www.rse-web.it/collanaRseview/Resilienza-del-Sistema-Elettrico.page

The first definition of a system ability known as resilience dates back to the seventies and has been used in various fields of knowledge since then. In the electricity sector, a universally agreed definition has not been established yet. Anyway, the current definitions focus on two basic characteristics, namely the ability of a system to absorb and limit the impact of disturbances, and to rapidly recover. Such definitions, however, fail to include other fundamental dimensions of this term and to provide stakeholders with a shared concept.

Experts from RSE - Emanuele Ciapessoni, Diego Cirio and Andrea Pitto, from the Energy System Development Department - supported the creation of a special group at CIGRE, a well-known international organisation dealing with electricity systems. In fact CIGRE has acknowledged that power system operation and planning must include a proper assessment of the risks due to the system exposure to natural and man-made hazards.

The publication on CIGRE's official magazine “Electra” of the definition of resilience with a key contribution from the team of RSE experts paves the way to a shared concept of resilience and its applications.

This is a substantial step towards the set-up of a rigorous framework for this system ability that is becoming increasingly important for operators and regulatory authorities, both in Italy and abroad.


Note

The work group C4.47 at CIGRE [Conseil International des Grands Réseaux Électriques] - Task 1: Definition of Power system resilience established the official definition published in the Reference Paper  contained in issue no. 306 (October 2019) of its  magazine “Electra “.
