Electricity and a dependable power supply are essential to contemporary life, as individuals rely on electrical systems to support nearly every facet of their daily routines. The constant availability of electricity is vital for households, businesses, and essential services, establishing power networks as a fundamental backbone of modern society. Nevertheless, disasters or calamities, some of the earliest challenges encountered by humankind, present considerable threats to these systems. As communities become more dependent on electricity, it is vital to tackle these issues from the viewpoint of electrical power systems. This paper introduces the Electricity Power Supply Network Simulation Model to examine the effects of accidental disasters on regional power networks and their ability to withstand such events. The main goal is to examine the percentage variation in power flow and the level of power loss in different node failure situations. The study investigates instances of single-node failure, and partial node failure, in which merely a segment of a node's capacity is affected. Furthermore, a streamlined network diagram is created to illustrate the power demand system in Kosovo, offering insights into the weaknesses and functionality of the electrical grid during disaster related interruptions.
