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
