“…Generators in this system have high robustness to spoofing attacks. Two possible explanations include the initial higher load rate Q (Q ij = f ij /C ij ) of these branches (such as Q (6,11) = 70.4%, Q (16,19) = 76.7%, Q (21,22) = 67.7%, and Q (21,22) = 59% (Q average = 35.9%)) and the unreasonable partial design of topology (like branch (2,25).

“…In these models, the impacts of cyber attacks are simplified to load curtailment or cutting off overloaded branches. Nezamoddini et al [21] addressed the problem of the transmission system security with an optimization model and measured the damage of cyber attacks in terms of the load curtailment. Stefanov and Liu [22] modeled the system based on characteristics of generators for identification of cyber-physical system vulnerabilities, security enhancement, impact analysis, and mitigation of cyber attacks.…”

The integration of modern computing and advanced communication technologies with power grids has led to the emergence of electrical cyber physical systems (ECPSs). However, with the massive applications of communication technologies, power grids are becoming more vulnerable to cyber attacks, and there is no general model for analyzing the influence of such attacks. This paper focuses on modeling ECPSs considering cyber security. A multiple characteristic association (MCA) approach is proposed for analyzing cascading failures and cyber attacks based on the DC power flow model. It can comprehensively and qualitatively formulate the characteristics of power grids, communication facilities, and their interdependent relationships. The proposed model approach has good expansibility when analyzing the mechanism and impacts of cyber attacks. Three possible cyber attack scenarios (denial‐of‐service attack, uplink spoofing attack, and downlink spoofing attack) are qualitatively studied. Simulation results with IEEE systems verify that cyber attacks happening on information uplinks or downlinks have different impacts on power grids. © 2018 Institute of Electrical Engineers of Japan.

The integration of natural gas in electricity network requires a more reliable operating plan for increasing uncertainties in the whole system. In this paper, a threestage robust optimization model is proposed for resilient operation of energy system which integrates electricity and natural gas transmission networks with the objective of minimizing load curtailments caused by attacks. Nonconvex constrains are linearized in order to formulate the dual problem of optimal energy flow. Then, the proposed three-stage problem can be reformulated into a two-stage mixed integer linear program (MILP) and solved by Benders decomposition algorithm. Numerical studies on IEEE 30-bus power system with 7-node natural gas network and IEEE 118-bus power system with 14-node natural gas network validate the feasibility of the proposed model for improving resilience of integrated energy system. Energy storage facilities are also considered for the resiliency analysis.
