IEEE Power & Energy Society (PES) Power System Relaying and Control (PSRC) Committee

PES Power System Relaying and Control (PSRC) Committee is responsible for the development of standards, guides and reports covering different aspects of protection and control of electric power systems.

We are pleased to share an update on PSRC’s subcommittees and working groups, who are diligently working on numerous Standards, Guides, papers, etc. for our industry.

Technical Paper Coordinator Report:  At the IEEE general meeting in July 2023, 21 papers were accepted.  Also, PSRC hosted four panel sessions:

  • Integrating Relay Models with RMS Dynamic Simulations – Protection Perspective
  • Developing AI/ML applications for power system protection & control – Opportunities and Challenges
  • Augmenting power system protection & control – Industry perspectives and case studies of practical AI/ML applications
  • New developments to mitigate power line induced wildfire ignitions

Associate Management System: PSRC members should create a new profile on memberplanet.  If you haven’t created your profile, please do so.  It is required to update you on PSRC activities and maintain voting member status on any roster.

IEEE 1547:  Call to action for IEEE PSRC members for IEEE 1547-2018 and 1547.4-2011 Revisions that are underway, and for participation in P1547.10:
