System-Level Design for Reliability of Microgrids Considering Power Electronic Failures
In IEEE International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2022
Abstract
This paper investigates and quantifies the consequences of ignoring power converter failures in the system-level design of microgrids. To achieve this goal, the process of converter-level reliability modeling, calculating the availability, and finally obtaining the system-level reliability indices are explained. A model-based and mission profile-based system-level design methodology has been used, which considers both reliability and cost. Further, the methodology has been implemented in a case study, once considering and once ignoring the power electronic failures. Accordingly, it has been shown that ignoring the converter failures can lead to an unreliable system-level design and jeopardizes its cost-effectiveness in the long run.
