“…However, the self-regulating function of the generators and the economic power dispatch have not been considered in the above-mentioned cascading failure models. Li et al (2017a; built an AC cascading failure model considering bus load shedding and AC optimal power flow analyses. The self-regulating function and economic dispatch are considered in their models.…”

The Cyber-Physical Power System (CPPS) is one of the most critical infrastructure systems in a country because a stable and secure power supply is a key foundation for national and social development. In recent years, resilience has become a major topic in preventing and mitigating the risks caused by large-scale blackouts of CPPSs. Accordingly, the concept and significance of CPPS resilience are at first explained from the engineering perspective in this study. Then, a review of representative quantitative assessment measures of CPPS resilience applied in the existing literature is provided. On the basis of these assessment measures, the optimization methods of CPPS resilience are reviewed from three perspectives, which are mainly focused on the current research, namely, optimizing the recovery sequence of components, identifying and protecting critical nodes, and enhancing the coupling patterns between physical and cyber networks. The recent advances in modeling methods for cascading failures within the CPPS, which is the theoretical foundation for the resilience assessment and optimization research of CPPSs, are also presented. Lastly, the challenges and future research directions for resilience optimizing of CPPSs are discussed.

“…Therefore, in well-known studies, value k does not exceed, as a rule, 3 or 4. To substantiate the practical sufficiency of these values, it should be noted that, starting from them, there is a good degree of correlation between the assessments of the importance of the elements obtained at different k [31].…”

A new approach to creating a domain-specific heterogeneous distributed computing environment is considered. It is used to support decision-making on urgent problems of increasing the survivability of energy systems. The approach is based on the use of high-performance computing, multiagent scheduling of computations and resource assignment, tools for processing semistructured information, and visualization of subject data using electronic maps. Decision-making alternatives are evaluated using combinatorial modeling and multicriteria optimization. Orlando Tools is used as the base for the environment's integrated software. It implements flexible modular construction of scalable scientific applications (distributed application packages). The advantages of using the environment are demonstrated by the example of solving practical problems.

“…A promising tool for building DSSs is represented by Bayesian Networks. These are network of random variables used to represent in an efficient manner the uncertainty in a problem and for which efficient methods have been developed to perform Bayesian inference (Nielsen and Jensen 2009). The latter, i.e.…”

Most of the literature on resilience is devoted to its assessment. It seems time to move from analysis to design, to develop the tools needed to enhance resilience. Resilience enhancement, a close relative of the less fashionable risk mitigation, adds to the latter, at least in the general perception, a systemic dimension. Resilience is often paired with community, and the latter is a system. This chapter therefore discusses strategies to enhance resilience, endorses one of prevention rather than cure, and focuses in the remainder on the role played by systemic analysis, i.e. the analysis of the built environment modelled beyond a simple collection of physical assets, with due care to the associated interdependencies.Research needs are identified and include challenges in network modelling, the replacement of generic fragility curves for components, how to deal with evolving state of information.
