NERC-WECC Coordination MVWG meeting, San Diego March 2016

WECC LMTF Approach Old Approach New Approach Phase 1 (done) Phase 2 Implement AC stalling Implement a bunch of other improvements also New Approach Phase 1: implement structural improvements (test through beta implementations, i.e. CMPLDW1a, CMPLDW1b, CMPLDW1c etc.) Efficient data representation Improved tripping Distributed generation Robust initialization Phase 2: enable AC stalling (need to better understand phenomenon, make take a while)

Future Vision 1-2 years 2-5 years 5-10 years 10+ years Consistent, robust rules for initialization (phase 1 and phase 2) Efficient data management Improved Protection Modeling Load Model Data tool development Benchmarking between software programs (phase 1 and 2) 2-5 years Electronically Coupled Load Component Model Flexibility (Plug and Play Capability) Improved Air Conditioner Models Updates to Distributed Solar Generation and Energy Storage Models Model Validation studies 5-10 years Collecting and Coordinating load model data Adopt CLM for steady state studies 10+ years Promote CLM as standard load model for bulk grid studies (IEEE wide) Collecting and coordinating load model data (i.e. getting climate zones and feeder types right, getting DG right, getting protection and control parameters right)

WECC LMTF Priorities Priority 1: Robust initialization rules Priority 2: Improved Protection Modeling Priority 3: Efficient Data Management Priority 4: Benchmarking between programs Priority 5: Distributed Generation

NERC LMTF task list WECC MVWG participation. Certain tasks WECC LMTF will take the lead on here. Other tasks NERC will focus on

Coordination NERC LMTF meets 2-3 times per year NERC LMTF will coincide with WECC LMTF meeting once per year WECC will take lead on certain topics
