Incorporating Power Electronic Converters Reliability Into Modern Power System Reliability Analysis [PDF]

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2021
This article aims to incorporate the reliability model of power electronic converters into power system reliability analysis. The converter reliability has widely been explored in device- and converter-levels according to physics of failure analysis. However, optimal decision-making for design, planning, operation, and maintenance of power electronic ...
