Analysing Power System Component Failures under Two-state and Three-state Weather Models

Power transmission and distribution systems are highly susceptible to disruptions caused by the physical environment, particularly during extreme weather events. Extreme weather has a significant effect in power system and this vulnerability can lead to cascading failures and widespread power outages. To improve the system resilience, it’s crucial to assess the impact of weather conditions on component failures. This paper explores the influence of weather on power systems by evaluating two models: a two-state weather model and a three-state model. By analyzing these models, this article aims to understand the effect of varying weather severity on component failure rates and overall reliability of power systems. Also, through this work the results are compared according to the weather conditions and repair times.
