A Special Issue on Resiliency in Smart Grids - Part 1

By Mathaios Panteli, Rodrigo Moreno, and Pierluigi Mancarella

The catastrophic impacts of natural hazards and extreme weather events are witnessed worldwide. Only in the summer of 2018 in Europe, multiple such events spread chaos and resulted in disastrous impacts on critical infrastructures, including the electrical power system. Europe has experienced once again severe wildfires with large impacts on power assets, mainly in the Mediterranean region (for example Greece and Portugal) as well as in places nobody has foreseen or could ever imagine, like in North Sweden and as far as the Arctic Circle. Further, there were flash floods in many countries like France, while at the same time severe droughts and heat waves affected the entire Europe creating heavy additional and unpredicted burden on the electricity system. For example, in the last week of June in UK, high temperatures resulted in an increase of 860MW in the electricity demand, equivalent to an additional 2.5 million households.

Smart grid applications concern the management of an unprecedented number of interdependent and interacting cyber-physical systems (CPS). Employing such applications in modern power systems enables advanced situational awareness and emergency response in the rise of load stress, extreme weather, and attack threats. To keep the risks of massive blackouts at bay, it has become imperative to extend our understanding of failures across both cyber and physical layers, while enriching our solutions to resilience against both faults and threats. This article will review critical challenges to the analyses of contingencies and adversaries in the smart grid then provide a summary of recent advancements from testbeds to tactics for the enhancement of cyber-physical resilience in future power grids.

Cyber-threats are challenging the resilience of power systems in ways uncommon to ‘classic’ operational risks of equipment failures and natural disasters. As an example, consider an attacker who monitors operator actions after a cyber-attack and who persistently blocks any operator attempt to mitigate the impact of the attack. Such immediate reply to operator actions is deliberately constructed, thoroughly thought of, and, typically, well-funded by malicious sources. To accommodate such cyber-attack characteristics, the resilience thinking must expand into the cyber-physical domain in which power systems, information technology (IT) and operational technology (OT) are considered as one system under scrutiny.

Resiliency is an important topic that is growing in relevance, both in a traditional sense (i.e., being prepared to survive storm events), but also in terms of a utilities’ capability to be prepared for the utility landscape of the future (i.e., grid modernization). The quest for greater utility resiliency is therefore an on-going pursuit that continuously takes shape over time.
