Title: Distribution system versus bulk power system: identifying the source of electric service interruptions in the US

Abstract

This study reports on the results from efforts by the Institute of Electric and Electronics Engineers (IEEE) Distribution Reliability Working Group (DRWG) and the U.S. Energy Information Administration (EIA) to improve the usefulness of reliability metrics by developing and then applying consistent, yet distinct measures of the continuity of supply based on the portion of the electric power system from which power interruptions originate: the lower voltage distribution system versus the high-voltage bulk power system. The modified metrics better support reliability planning in the US because they separately measure the effectiveness of actions to improve reliability made by the two distinct groups of firms (and their regulators or oversight bodies) that are responsible for planning and operating each portion of the US electric power system. The authors then present for the first time quantitative information on the reliability of each portion of the US electric power system. When reliability is measured using the system average interruption duration index and the system average interruption frequency index, they find that the distribution system accounts for at least 94 and 92%, respectively, of all interruptions. They also find that these relationships have been stable over the recent past.

Evaluating the Performance of the IEEE Standard 1366 Method for Identifying Major Event Days

Journal Article Eto, Joseph H. ; LaCommare, Kristina Hamachi ; Sohn, Michael D. ; ... - IEEE Transactions on Power Systems

IEEE Standard 1366 offers a method for segmenting reliability performance data to isolate the effects of major events from the underlying year-to-year trends in reliability. Recent analysis by the IEEE Distribution Reliability Working Group (DRWG) has found that reliability performance of some utilities differs from the expectations that helped guide the development of the Standard 1366 method. This paper proposes quantitative metrics to evaluate the performance of the Standard 1366 method in identifying major events and in reducing year-to-year variability in utility reliability. The metrics are applied to a large sample of utility-reported reliability data to assess performance of themore »« less

Spatiotemporal Variability of Electric System Reliability Metrics

Conference Singh, Nagendra ; Omitaomu, Femi

As urbanization continues to grow, urban density also rises, placing significant stress on critical infrastructure. Cities often face challenges in investing in new infrastructure or upgrading existing ones. One area of infrastructure that has come under strain is the electric grid, leading to prolonged power outages. According to data from the U.S. Energy Information Administration, the average duration of power outages has steadily doubled from 2013 to 2021, primarily due to extreme weather events. The IEEE has developed a series of reliability metrics to assess the reliability of the electric system. However, these metrics are only applied at the utilitymore »« less

A Quantitative Assessment of Utility Reporting Practices for Reporting Electric Power Distribution Events

Journal Article Hamachi La Commare, Kristina - 2012 IEEE Power & Energy Society General Meeting

Metrics for reliability, such as the frequency and duration of power interruptions, have been reported by electric utilities for many years. This study examines current utility practices for collecting and reporting electricity reliability information and discusses challenges that arise in assessing reliability because of differences among these practices. The study is based on reliability information for year 2006 reported by 123 utilities in 37 states representing over 60percent of total U.S. electricity sales. We quantify the effects that inconsistencies among current utility reporting practices have on comparisons of System Average Interruption Duration Index (SAIDI) and System Average Interruption Frequency Indexmore »« less

A procedure for evaluating interrupted energy assessment rates in an overall electric power system

Journal Article Goel, L ; Billinton, R - IEEE Transactions on Power Systems (Institute of Electrical and Electronics Engineers); (United States)

There is an increasing interest in economic optimization approaches for power system planning and expansion. Evaluation of the cost associated with different system configurations and the corresponding reliability worth at the customer end is generally termed as reliability cost/worth assessment. The actual or perceived costs of customer interruptions can be used to determine the worth of electric service reliability. This paper presents a method for evaluating an Interrupted Energy Assessment Rate (IEAR) at each system customer load point considering the influence of outages in all parts of the electric power system. The developed IEAR can be used with the availablemore »« less

Delivery point reliability measurement

Conference Chowdhury, A A ; Koval, D O

Reliability is one of the most important criteria which must be taken into consideration during the planning, designing and operating phases of any industrial, commercial or utility power system. Two distinct reliability assessment methodologies are frequently used to evaluate the reliability performance of power systems. They are: (1) historical reliability assessment, i.e., the collection and analysis of system outage data, and (2) predictive reliability assessment, i.e., combining historical outage data and theoretical models to estimate the performance of various power system operating configurations. This paper will focus on the historical assessment of the sustained frequency and duration of single circuitmore »« less
