Abstract
Given that a continuous power supply is fundamental to the economy and human well-being, development of a self-sustained electrical system that can withstand sudden disturbances by employing both renewable energy and storage technology is of significant importance. Most of the existing reliability approaches hardly represent a particular method of analyzing system adapting ability to remain self-sufficient in the short-term after the occurrence of sudden disruptions. In addition, existing reliability indexes are developed based on past experience, hardly covering the prediction of disruption risks. As such, a new electricity reliability quantification approach dedicated for sudden disruptions was established and the newly proposed electricity reliability prediction index was evaluated. The developed index was applied to determine optimal capacity sizing in the context of energy security. The availability of such electricity reliability predictions will allow the facility engineer to make wiser decisions to maintain a continuous power supply even after the occurrence of sudden disturbances. The developed algorithm can be readily implemented in any electrical system network including microgrid and rural electrification.

The objective of this paper is to develop the methodology for evaluating system adapting ability to remain self-sufficient in a short-term period after the occurrence of sudden disruptions, to establish a new electricity reliability index dedicated to the power security aspect, and apply the developed index into determining optimal capacity sizing in the context of energy security
Summary
In a recent times electricity grid systems have been reconsidered in response to the occurrence of extreme events. Self-sustained distributed grid systems were developed on the basis of local electricity production for local consumption. Utilization of both renewable energy and storage technology is highly matched with the concept of a self-sustained distributed grid. Storage technologies such as batteries are useful to address the issues of renewable energy including intermittencies. Given that continuous power supply is fundamental to the economy and human well-being, the development of self-sustained electrical systems to withstand sudden disturbances by employing both renewable energy and storage technology is of significant importance in all energy intensive sectors
