A capital light solution to increase power system resilience against wet snow: the Italian experience with anti-torsional devices

The article describes the quantification of the benefits of anti-torsional devices, a capital-light measure to reinforce the power system infrastructure against wet snow events, within the Terna-RSE risk-based methodology for resilience assessment.

It is essential for TSOs to have tools and methods to evaluate the benefits of network operations during the planning phase, also considering extreme weather events, which are increasing in frequency due to climate change. The concept of resilience, therefore, plays a key role in dealing with extreme weather events and improving system performance.

 

This paper describes anti-torsional devices, a capital-light measure to reinforce infrastructure against wet snow events. To quantify their benefits, a model of these devices is proposed and applied within Terna-RSE’s risk-based methodology aimed at assessing investments to enhance the resilience of the power system. A case study on a portion of the Italian HV/EHV network demonstrates the effectiveness of the model and the potential of the Terna-RSE tool to perform a quantitative techno-economic assessment of the resilience measures portfolio.
