Part 2: Brief presentations from SC/WG/TF liaisons on 100% Renewables

Selected in-depth reports from IEEE PES SC/WG/TF related to 100% Renewables (or towards 100% renewables penetration levels) and other relevant wind and solar reports:


Deepak Ramasubramanian – PSDP’s Task Force on Modeling and

simulation of large power systems with high penetration of inverter-based generation –

focus on low inertia issues

  • Approved at last GM, first in person on 8/7 (also Webex) – 2 year timeframe
    • Focused on kinds of simulation models needed – when to use different models (e.g. Pos seq, dynamic phasor, EMTP) and which are the right models (generic, user-defined, etc.)
    • Not trying to advocate for any specific approach, but laying out pros and cons of different types
    • Suggestion of starting on this w/issue paper (Guohui)


Manish Patel – EDPG’s P2800 on transmission-level interconnection

of inverter-based resources

  • Started earlier this year
    • 270 interested parties – OEMs/vendors/consultants speak up most, need tx planners/protection eng to ensure balance
    • 11 subgroups
    • Want to go to ballot by summer 2020
    • 1 is entity std, 2800 is individual 0 2800.1 is still open to participation but entity voting
    • Related IEC activities – SC8A JWG4 – testing standard


Ryan Quint Update on SPIDERWG

  • System Planning impacts of DER WG – looking at bulk system planning side of DER integration
    • Built on DERTF (provided overview of issues rather than fixing the problem)
    • Coordinating w/NATF, EPRI and others
    • Published 2 reliability guidelines on modeling DER – current status quo
    • Four subgroups (200 people) – Modeling, verification, studies, coordination

Discussion focused on technical issues (how to represent distribution, need for individual vs aggregated data, and verification methods)


Babak Enayati – T&D’s Distribution Subcommittee and Distributed

Resources Integration Working Group

  • Look at technical interconnection stds/requirements – integration into dist system plus transmission impacts
    • Sponsored 1547.2 – guide for applying, and 1547.9 – storage
    • Technology agnostic – anything directly connected to dx
  • 2 active task forces – microgrids, energy storage
  • 2 new TFs
    • Interconnection of DER – gaps, bottlenecks, etc. – guide for how to do this
    • Anti-islanding protection – existing and new methods for protection
  • T&D committee only has dist committee
    • Babak to propose more involvement for transmission
  • How is it coordinated w/SPIDERWG?
    • Coordinated through 1547, 2800, etc.


Charlie Smith – ESIG’s Towards 100% Workshop

  • Follow on from IIESI activities to broader roadmapping exercise
    • 100% instantaneous as bookend, but really looking at high penetrations
    • Loosely coordinated fashion across different entities
    • 5 workshop tracks – outcomes
      • ID needs for operating seamlessly
      • Move beyond 80% to 100% annual energy – how to analyze?
      • Putting pieces together – where we are, what needs to be done, etc.


Guohui Yuan – DOE Solar Integration program

  • New goal for cost reduction – 3c/kWh LCOE
  • System integration – affordability, resiliency, reliability, cybersecurity
  • Annual budget $250m – $50m to system integration
  • 80 active projects in SI (300 in SETO)
  • Approach – services, planning and ops, controls and enabling tech
    • DOE Grid Mod Initiative – across all DOE programs (EERE, OE, FE, NE, CESER)
    • Coordination w/DOE and IEEE – looking at gaps and research needs
  • Moving from high TRL projects to lower TRL/early stage so less direct utility engagement


Gary Kobet – IEEE/NERC’s Impact of Inverter Based Generation on

Bulk Power System Dynamics and Short-Circuit Performance – focus on protection


  • Technical report identifying problems (TR-68)
    • Tutorial given in April
    • BC Hydro reported issues
    • Protection covered in one section and subgroup
  • How relay elements respond, UFLS with low inertia, frequency tracking, relay scheme selection
  • Examples of problems for different types of relays
    • Elements based on current level – w/IBRs hard to tell
    • Even distance elements have current thresholds
    • Can you use different relay schemes?
  • Which cases should be run?
    • Run simulations for short circuit ratio
    • Short circuit program modeling – EPRI and others working on this, no longer a gap
    • PSRC WG C32 – paper on gaps/recommendations
  • How many challenges would fall off list if negative sequence was produced by IBRs
    • P2800 could provide some guidance/requirements on this
  • These issues are already killing projects where relays would have to be completely changed out, etc.


Gaps, Needs, Next Steps (all)

  • Supersessions for 2020
    • Submit Charlie for ESI, YC for big data
  • For reviewing papers – better to pass onto relevant committees or keep w/WSPCC?
    • Can we come up with number and scope for what we are willing to review?
  • Proposing our own session – we have until Nov. Ideas include:
    • High penetration projects and how they work
    • DOE program on critical infrastructure w/DER
    • PV+storage hybrid
  • Follow up – conference call among officers in next 1-2 months
