A resilient power system reduces the likelihood
Power Systems'' Resilience: A Comprehensive Literature Review
Several natural hazards have caused unexpected problems to power systems due to climate change, emphasising the position that power systems are not prepared for extremely large-scale events. As a result, the need to study resilience in the context of power systems has been increased. A comprehensive review of the literature on power system resilience (PSR)
Resilience
Resilience refers to the ability of a power system, especially microgrids, to withstand disturbances and quickly recover to its normal operating conditions. This concept is crucial in ensuring that energy systems can adapt and maintain functionality in the face of challenges such as outages, extreme weather, or component failures, thus enhancing reliability and stability.
Methods for Analysis and Quantification of Power System Resilience
Quantification can analyze existing power systems and identify resilience improvements in future power systems. Given that a 100% resilient system is not economic (or even technically achievable), the degree of resilience should be transparent and comprehensible. Several gaps are identified to indicate further needs for research and development.

6 FAQs about [Power system resilience definition]
What is power system resilience?
Enhancing power system resilience means an improvement in the capabilities required at various operating stages of a power system. In other words, it can involve enhancing the system’s anticipative capabilities before an event, as well as its capabilities to resist, withstand, absorb, adapt, and recover after an event.
What makes a power system resilient?
A power system should possess the following five features to be considered resilient: the ability to anticipate, survive, sustain, recover from, and adapt to a given threat event. These five features form the basis for a newly proposed power systems resilience taxonomy, as shown in Fig. 4.
Why is resilience important?
In order to make the power grid more flexible and intelligent and to better withstand natural disasters, the concept of resilience has recently been applied [2, 3]. Extreme events have the potential to cause significant power outages, making it crucial and urgent to enhance the resilience of the power system .
Does power system resiliency compare with reliability?
The technical background of the power system resiliency comparing with reliability is presented. The proposed quantitative metrics from both operational and infrastructure aspects are discussed to understand the requirements better. The potential threats are categorized, such as natural disasters and cyber-threats.
Are power system resilience metrics standardized?
Although several power system resilience definitions, metrics, and evaluation methods have been proposed in the literature, they have not been universally accepted or standardized.
What is a resilient system?
Resilient systems, when dealing with disruptions, are designed to “bend” instead of “break”, meaning they must possess flexibility and survivability. For instance, utilizing emergency power sources to provide temporary support or reconfiguring system configurations will enhance a system’s flexibility .
