This paper presents an improved interdiction model to identify maximal electric grid attacks. The contribution of the model is that it incorporates both short-term (seconds to minutes) and medium-term (minutes to days) impacts of the possible attack. The medium-term impacts are examined by an interdicted dc optimal power flow model. The short-term impacts are addressed by a cascading outage analysis model that uses a set of sequentially applied checkers to perform the simulation of the cascading outage events and assess the short-term impacts of a blackout subsequent to specified terrorist attacks. An integer programming heuristic is applied that can utilize standard optimization software (e.g. CPLEX) to solve master problems generated by the heuristic. The proposed model has been verified using the IEEE 300-Bus Test System and IEEE RTS 96 Test System. Discussions of the results and future research plans are also presented in this paper.Index Terms-Cascading outages, interdiction, power flow, power system security.

“…However, it is assumed that at every node in the physical domain there is a sensor or measurement that can form inputs to the power system analysis. The COA tool used in this work was developed first in [51], and improved in [52, 53]. The framework of COA is described in Fig.…”

“…The status and dispatch set point of units at the termination of the PowerWorld transient analysis are used as a starting point for the PowerWorld AC power flow simulator. A normal inverse‐time over‐current model described in Siemens SIPRO‐TEC 5 Current Relay [51] is implemented as OOC in COA. This checker in effect produces change in the physical domain graph by removing an edge.…”

Generalised resilience models for power systems and dependent infrastructure during extreme events

This study presents a generalised critical infrastructures resilience model for extreme events with a focus on power grids. Infrastructures are modelled as three domains-physical, cyber, and human. Each domain is described with respect to the services it provides. Each domain is represented by geometric graphs for each service it provides. The resilience models use geometric graphs with each graph's nodes and edges characterised based on relevant attributes. This study also discusses various applied aspects related to resilience models including the impact of changing operating environment, human-driven processes, such as logistics, and service buffers. Due to their stated particular importance in the U.S. Presidential Policy Directive 21, particular attention is placed on the power infrastructure and its impact on the public communication infrastructures as a main critical load. This study focuses on the multi-time scale power system operation to capture cascading outages within, and subsequently to its dependent infrastructure-the public communication system (e.g. wireless or 'cellular' communication networks) as a main critical load. This study illustrates the merits of the proposed models in calculating resilience in extreme events and derives physical domain representation for electric and communication systems using cell tower and substation data from the USA.

“…On the other hand, the state of the art in power system engineering can model cascading failures with realism: for instance, [79] considers both short and medium term outage effects, and includes representations of e.g transient and frequency stability in the cascade simulation [80]. Of those engineering works that consider intentional attacks, optimal power flow techniques are popular for identifying sets of power system components to attack [81]- [83].…”
