  • Interdependence between power grids and communication networks: a resilience perspective
    Publication . Martins, Lúcia; Girão-Silva, Rita; Jorge, Luisa; Gomes, Álvaro; Musumeci, Francesco; Rak, Jacek
    Power network resilience is increasingly dependent on communication networks. Besides traditional generation, power networks need to accommodate increasingly high penetration levels of dispersed micro generation, mostly based on renewable sources, and increasing and challenging demand, such as electric vehicles. At the same time the deployment of enabling technologies throughout the power grid makes available new demand resources and storage capacity. These resources have to be jointly managed for efficient and resilient operation. Therefore a resilient communication network is mandatory for the smart control of these different resources. Communication networks in turn also rely on the power networks in spite of some power backup that they may have. This interdependence is especially critical in bad weather conditions where both networks can be severely affected, even more when they strongly depend on each other. This work describes ongoing research related with the interdependence between both networks regarding resilience, cascading failure effects, applicable models and simulation techniques.

    Due to the increasing dependence on network ser- vices of our society, research has recently been concentrating on enhancing traditional protection strategies to withstand large- scale failures, as in case of disaster events. The recently-formed EU-funded RECODIS project aims at coordinating and fostering research collaboration in Europe on disaster resiliency in com- munication networks. In particular, the Working Group (WG) 2 of the RECODIS project focuses on developing new network- resiliency strategies to survive weather-based disruptions. As a first step, WG2 members have conducted a comprehensive literature survey on existing studies on this topic. This paper classifies and summarizes the most relevant studies collected by WG2 members in this first phase of the project. While the majority of studies regarding weather-based disruptions deals with wireless network (as wireless channel is directly affected by weather conditions), in this survey we cover also disaster- resiliency approaches designed for wired network if they leverage network reconfiguration based on disaster “alerts”, considering that many weather-based disruptions grant an “alert” thanks to weather forecast.
