In recent years, climate changes caused an increase of violent and wide-ranging meteorological events, often with significant effects on the power systems continuity of service. Moreover, evolutions of users' habits and the increasing dependence on the electric energy carrier are motivating the request for a more and more reliable power supply. In this framework, the work presents a methodology aimed at evaluating the resilience of electric distribution grids against interruptions due to the ice and snow sleeves accretion on overhead lines. The approach proposed is applied to the MV network supplying the Vizze Valley, managed by the Italian DSO Edyna, and represents an essential step to perform a selection of the corrective actions to be implemented on the network according to their expected benefits and costs.

Abstract
In recent years, climate changes caused an increase of violent and wide-ranging meteorological events, often with significant effects on the power systems continuity of service. Moreover, evolutions of users' habits and the increasing dependence on the electric energy carrier are motivating the request for a more and more reliable power supply. In this framework, the work presents a methodology aimed at evaluating the resilience of electric distribution grids against interruptions due to the ice and snow sleeves accretion on overhead lines. The approach proposed is applied to the MV network supplying the Vizze Valley, managed by the Italian DSO Edyna, and represents an essential step to perform a selection of the corrective actions to be implemented on the network according to their expected benefits and costs.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
