Reliability Assessment of Power Electronics Devices and Systems for Modern Power Applications

Abstract

Renewable energy sources are increasingly becoming predominant factors within the power networks. They are reshaping power systems into more decentralized, self-sufficient structures in conjunction with reducing carbon emissions. The terms “Smart Grid” and “Microgrid” come into play when distributed energy resources assume control. While these advancements enhance technical efficiency, financial viability, planning, operations, and reduction of carbon emissions; they also bring forth novel challenges. Among these, reliability is a significant concern, necessitating a fresh approach to defining and evaluating the dependability of both systems and components. The chapter presents an innovative reliability framework for power electronic devices and systems encompassing these novel facets of contemporary power systems. Notably, evaluating reliability in modern power systems demand the inclusion of local reliability concepts and the integration of diverse electromagnetic and mechanical stability concerns. © 2024 by The Institute of Electrical and Electronics Engineers, Inc.
