Solution Reliability Evaluation Of Engineering Systems By Roy Billinton And -

For a power system with total generation capacity C and load L (which varies over time), LOLP = Probability (C < L).

The phrase "Reliability Evaluation of Engineering Systems" is not just a technical term; it is the title of the seminal 1983 (and later 1992) book by and Ronald N. Allan . If modern engineering has a bible for quantifying the unquantifiable—the probability that a bridge will stand, a grid will supply power, or a plant will operate without failure—this is it. For a power system with total generation capacity

But they went further. They developed the in days/year, and the Expected Energy Not Supplied (EENS) in MWh/year. These indices became regulatory standards. If modern engineering has a bible for quantifying

A cut set is a set of components whose failure causes system failure. A minimal cut set is the smallest such set. These indices became regulatory standards
