CIGRE Working Group B2.77
Problem statement
Transmission and distribution overhead line networks face a variety of operational risks stemming from severe climatic events.
These events impact the safe operation and maintenance of the network, reliability, customer service, public safety, and environmental well-being. Additionally, these can lead to significant financial/ legal costs and reputational damage for network owners/ operators. As the energy landscape shifts towards greater reliance on renewable sources, existing ageing assets pose an additional risk to overall grid stability and reliability – resilient networks are required.
What have we developed?
CIGRE B2.77 developed a generic risk management framework and a resilience-based risk index model “ReBRi”. This framework considers both simplified and detailed interdependencies, allowing a wide range of stakeholders to assess operational risks for a given network in a relatively short timeframe compared to the complex frameworks available.
