Abstract--Power systems are prone to cascading outages leading to large-area blackouts, and intentional controlled islanding (ICI) can mitigate these catastrophic events by splitting the system into sustainable islands. ICI schemes are used as the last resort to prevent cascading events; thus, it is critical to evaluate the corresponding system risks to ensure their correct operation. This paper proposes a unified framework to assess the risk of ICI schemes. First, a novel ICI method to create islands with minimum power imbalance is presented. Further, a risk assessment methodology is used to assess the probability and impact of the main operational modes of the ICI scheme. The unified framework provides insights on the benefits of implementing ICI, considering the uncertainties related to its reliability. The ICI scheme is demonstrated using the IEEE 9-bus system. The proposed unified framework is then fully deployed on the actual power system of Cyprus. Multiple case studies on the real network are created to demonstrate the adaptability and robustness of the proposed scheme to different system conditions. The adoption of the unified framework highlights that the system risk significantly reduces with the ICI in service, even when the reliability uncertainties associated with the scheme are considered.

“…Experts can follow best practice or good practice (Hummelbrunner and Jones 2013a) to establish resilience of specific parts of the system to specified shocks. However, these level 1 components can collapse when critical thresholds are exceeded in the level 2 systems context in which they are embedded (Pourbeik et al 2006, Simone 2014. General resilience therefore needs to be established across multiple facets of the level 2 system and necessitates resilience practitioners to embrace complexity-based approaches.…”

ABSTRACT. Essential services such as electricity are critical to human well-being and the functioning of modern society. These services are produced by complex adaptive socio-technical systems and emerge from the interplay of technical infrastructure with people and governing institutions. Ongoing global changes such as urbanization and increasing prevalence of extreme weather events are generating much interest in strategies for building the resilience of essential services. However, much of the emphasis has been on reliable and resilient technical infrastructure. This focus is insufficient; resilience also needs to be built into the human and institutional processes within which these technical systems are embedded. Here, we propose a conceptual framework, based on a complex adaptive systems perspective, that identifies four key domains that require investment to build the resilience of essential services. This framework addresses both the technical and social components of the socio-technical systems that underlie essential services and incorporates specified and general resilience considerations. The framework can be used to guide resilience assessments and to identify strategies for building resilience across different organizational levels.

“…A link is then defined as a connection between any a pair of such nodes. It has been demonstrated that many real world networks show community structure, such as power network [5], communication networks [6], and so on. To the best of our knowledge, synchronization of power network with community structure has not been previously investigated.…”
