Inertia and the Power Grid: A Guide Without the Spin
www.nrel.govInertia is only one of several grid services that help maintain power system reliability. Understanding the role of inertia requires understanding the interplay of inertia and these other services, particularly primary frequency response, which is largely derived from relatively slow-responding mechanical systems. 3.

RELIABILITY OF SYSTEMS WITH VARIOUS ELEMENT …
ocw.mit.eduThe reliability of a series system is easily calculated from the reliability of its components. Let Yi be an indicator of whether component i fails or not; hence Yi = 1 if component i fails and Yi = 0 if component i functions properly. Also denote by Pi = P[Yi = 1] the probability that component i fails.
Probability Distributions Used in Reliability Engineering
crr.umd.eduengineering with statistics. The reliability engineer’s understanding of statistics is focused on the practical application of a wide variety of accepted statistical methods. Most reliability texts provide only a basic introduction to probability distributions or only provide a detailed reference to few distributions.
