Reliability Assessment of DC Circuit Breakers and AC/DC Hybrid Distribution Systems Using Weibull Distribution

Due to the recent surge in inverter-based renewable energy sources and DC loads, investments research in DC distribution are progressing. To harness DC systems in industrial settings, it is imperative to establish various systems that ensure continuous power supply, especially during main power outages. In this paper, we aim to assess the reliability of optimally managed operational power components through the analysis of failure histories using the Weibull distribution function. Furthermore, this study seeks to ascertain whether satisfying the appropriate reliability criteria for DC circuit breakers enhances the reliability of AC/DC hybrid systems compared to traditional AC systems.
