Resilience of interdependent critical infrastructure

The power system is one of several infrastructure systems that are critical for the operation of fundamental societal functions. Electrical power is ubiquitous and other critical infrastructure systems depend on it, such as gas and water distribution networks, or telecommunication and transportation systems. The dependence is reciprocal, since the successful operation of many power system assets and processes requires natural gas, water, telecoms and, to an extent, transportation.

C4

System technical performance

The scope of SC C4 covers system technical performance phenomena that range from nanoseconds to many hours. SC C4 has been engaged in the following topics: Power Quality, EMC/EMI, Electromagnetic Transients and Insulation Coordination, Lightning, Power Systems Dynamics Performance, and Numerical Analysis. Study Committee C4 deals with methods and tools for analysis related to the technical performance of power systems, with particular reference to dynamic and transient conditions and to the interaction between the power system and its apparatus/sub-systems, between the power system and external causes of stress and between the power system and other installations.
