Presentation Contents

• This presentation will provide an overview of leading industry practices, standards and methodologies for evaluation and
  improvement of reliability and resiliency of distribution systems, including the following aspects:
•  Review of IEEE 1366-2012 Standard: including key definitions (outage, interruption, major event days, failure rates;
  mean-times-to-repair; etc.); distribution reliability indices (SAIDI, SAIFI, CAIDI, MAIFI, CEMI, etc.); major event exclusion
  methodology (2.5 beta method); resiliency, resiliency metrics, and application examples.
•  Classic and modern distribution reliability and resiliency improvement practices: including overcurrent protection
  philosophies (fuse saving, fuse clearing); reclosing (single-phase reclosing/lockout, three-phase reclosing/lockout, singlephase reclosing/three-phase lockout); distribution feeder automation (half-loop schemes, full-loop schemes, Fault
  Location, Isolation and Service Restoration (FLISR), fault circuit indicators, and sensors); vegetation management;
  weather hardening; aging infrastructure replacement; outage management and restoration (fault location,
  upstream/downstream restoration); real-time monitoring, protection, automation, control, and operations; utility
  enterprise systems (SCADA, OMS and AMI); and DER applications (microgrids and NWA).
•  Distribution reliability and resiliency modeling and simulation: review of software tools for distribution reliability
  modeling and analysis (CYME, Synergi, etc.); historical data analysis; model calibration; predictive reliability modeling;
  parametric modeling; benefit-cost analysis and prioritization; and development of reliability and resiliency improvement
  roadmaps.
•  Case studies: examples of distribution reliability and resiliency improvement roadmaps for real-life power distribution
  systems
