Abstract
The quality of the environment as well as public health is convincingly coupled with the functioning of a power subsector. The power subsector plays a pivotal role in the sense that it emerges as the key cross-sectional element for the society’s functioning (production, services, healthcare, education and others). A modern society consists of infrastructure systems that are primarily dependent on continuous electricity supplies. Each and every element of the electric power infrastructure is unique, and thus, its malfunction can disrupt the functioning of an important part of the electric power infrastructure. In conjunction with ensuring the functioning of electric power infrastructure, our attention must be drawn to the resilience issue. As far as the resilience of electric power infrastructure is concerned, it can resist weather-related events ensuring there are no disruptions in continuous electricity supplies. First, in the introductory part, the article presents the legal framework in the Slovak Republic. Second, it describes the current state of the electric power infrastructure of Slovakia. Third, it handles the state of the level of security risk assessment. Later on, in the literature review, besides turning to the issue of resilience assessment, the authors focused on the area of resilience of power engineering. Furthermore, the article scrutinizes resilience assessment in Slovakia, and it briefly examines approaches towards natural threats. In addition, the article demonstrates several approaches towards flood resilience. Having used different methods, the primary concern is to devise a framework for resilience assessment. Therefore, the included case study examines aspects of the proposed framework for resilience assessment. In conclusion, our aim was, in most respects, to outline an innovative methodological framework for increasing the resilience of electricity infrastructure.
Highlights
The beginnings of theoretical research and development of resilience are associated with the work published by Holling [1] in 1973
Database of specific methodologies coupled with exemplar instances by virtue of case studies with assumptions behind security, protections, vulnerability and resilience contributed to the national know-how
The element/object is characterized by a high level of absorption. This means that all necessary material and physical resources are sufficient so that the object/element can withstand the effects of an emergency and be able to provide basic services until the adverse effects of the emergency disappear
Summary
The beginnings of theoretical research and development of resilience are associated with the work published by Holling [1] in 1973. Various approaches were engaged to explain as well as to assess resilience. For the purposes of the article, we underscore the definition which approaches resilience as the ability to absorb, adapt and recover, in a timely manner, from the elements’ outage after an adverse event has occurred. In this context, our primary objective, based on elaborated analysis of information resources, is to suggest the methodological framework for the resilience assessment of electric power infrastructure. An example of such a weather-related event in practice was strong winds associated with a hurricane that attacked parts of our country on 24 October 2018
