Implication

Computational modeling study demonstrates significant risk underestimation in aging power grids, highlighting the need to integrate wear-out failure distributions into system planning.

Key Points

To develop and evaluate a calculation approach that incorporates aging-related component failures into existing power system reliability evaluation tools.
Formulated unavailability models for aging failures using normal and Weibull probability distributions structured identically to standard repairable failure rates.
Evaluated differences between the two distribution models and applied the methodology to a case study of the BC Hydro North Metro power grid.
Aging failures significantly reduced overall reliability indices, with the most severe reliability degradation occurring in mature or older power infrastructure.
Omitting aging failures from reliability assessments severely underestimated operational system risk, leading to potentially misleading planning decisions.
