Abstract :
Electrical utility reliability indices, such as SAIFI, SAIDI, CAIDI, CAIFI, and MAIFI are adequately defined in IEEE Std 1366-2012 [1] and serve the purpose for which they were developed. However, the explosive growth of the electronics industry moving toward an “internet of things,” along with the data center development necessary to support such explosive growth has had significant impact on an aging power distribution system. As the utility world evolves toward the notion of “smart grid,” several new reliability metrics are needed to evaluate the electrical power to the customer´s side of the meter.
