1. NERC LMTF Update Update on Key Topics
Dmitry Kosterev, Ryan Quint, Mohamed Osman, NERC LMTF
WECC LMTF Meeting
March 2017

2. Key Focus Areas Model benchmarking & uniform software implementation
Data quality checks – global parameters
Default data sets
Guideline on modeling DER in dynamic load models
Guideline on Modeling DER in Dynamic Load Models – APPROVED
Guideline on DER Modeling – UNDER DEVELOPMENT
Guideline on load developing composition data – APPROVED
Load modeling in real-time or operations studies
Industry webinar – COMPLETE
System studies forum

3. Benchmarking
Monitoring software vendors, EPRI, and industry efforts on benchmarking
Supporting coordination between groups as much as possible
Hoping for uniform implementation by June
Would like to inform NERC Planning Committee at June PC meeting!
Once complete, we can move on to other necessary topics
Uniform DER modeling implementation
Pushing DER modeling guidelines into practice

4. Default Data Sets
Continuing discussions and support on default data sets
Plan to expand default sets based on industry experience

5. Load Model Composition Guideline
APPROVED by NERC Planning Committee
Available on NERC PC Reliability Guidelines page

6. Industry Webinar Webinar complete and posted on NERC LMTF webpage
Please share with members with load modeling questions

7. Reliability Guideline: DER in Dynamic Load Models
Guideline on DER Modeling in Dynamic Load Models APPROVED
Sets adaptable framework for DER modeling
Use of U-DER and R-DER for modeling different types of DER
Next phase is to provide guidance/starting point for modeling U-DER and R-DER with actual models and modeling data

8. Survey on Dynamic Load Modeling in the Operations Horizon
Survey developed by NERC LMTF members
Survey sent to NERC LMTF members
Each operating entity expected to provide response
NERC Staff will be following up to ensure responses provided
Focuses
Benefits/needs
Relation to planning realm
Impacts on online transient stability analysis
Inclusion of induction motor load of some sort
Obstacles, challenges, path forward

9. Next Meetings In-Person Meeting:
April 18-19, 2017 in Atlanta, GA (NERC)
Full day/half day
In conjunction with NERC SAMS meeting
