Distributed Generation ModelingDistributed Generation Modeling CMPLDWg
REMTF proposed a simplified version of PVD1 to be added to the CMPLDW to create a CMPLDWg model
Initial testing with PSLF beta version has been performed
More work is planned to simplify the CMPLDW model, and will be coordinated with LMTF, SRWG, NERC MVWG and the program vendors
Proposed CMPLDWg for dynamic modeling
CMPLDWg = CMPLDW + DG
• Simple version of PVD1

System Model ValidationSystem Model Validation
System Model ValidationSystem Model Validation A priority of M&VWG is to continue efforts on enabling
the ability to transfer information between the WSM and planning base cases to be used for stability studies and perform system model validation.
M&VWG has a contract with GE to convert the WECC dynamic database to an “element code” definition with WSM. This would be a one time effort, and allow validation studies to be done using the WSM powerflow case and the new dynamic data file. This will lead to the ultimate goal where the planning model will also use a node-breaker model.
M&VWG is participating in the newly created TSS WBRTF effort
MVWG conducted model validation studies for Palo Verde and Arlington generation outage that occurred on July 4, 2012, and Chief Joseph breaker insertion.
Correlation was good and the composite load model did not show significant difference from the ‘interim’ load model
System Model ValidationSystem Model Validation Eric Allen, NERC, provided an update that most of the
efforts identified under NERC MVWG are currently under SAMS.
One of the NERC priorities is for each interconnection to be able to quickly prepare a model validation base case following a disturbance event. This effort will support the goal to reduce this time from weeks to hours.
DOE and BPA have funded research work by University of Wisconsin in developing methods for power system model validation to better match features of events. Additional effort will be put into prony analysis of the disturbance event.

Power Plant Model Validation
Power Plant Model Data Task Force Reviewed the list of suspected errors identified and
discussed at the PPMDTF conference call. Each item was assigned for follow up with the data owners to correct or verify the data that is suspect. If there are additional errors suspected, continue to send them to
Kent. Data checking and processing of new data
John Undrill provided a demo of the tool, which is continually being improved with new checks, delaying the user interface improvements
“DataCheckingConversionProgram.zip” is available on the WECC website in two locations
MVWG > PPMDTF > Documents Library > For Generators > Generator Testing Program
Excitation Models – OELExcitation Models – OEL IEEE working group expects to go to
ballot in 2013 with an OEL model (not the same as OEL1 and slightly different from IEEE OEL95)
More discussion is needed to determine which model WECC will recommend to be the approved OEL model
PSLF is continuing to connect the ES models with the OEL1 model
Excitation Models - UELExcitation Models - UEL UEL1 and UEL2 already exist Availability in the programs:
Available in PSSE version 32Will be available in next release of PSLFWill be implemented in PowerWorld
Thermal Governor Model
Revision of the thermal governor recommendation may be needed to reflect the appropriate participation from gas turbines based on the latest disturbance validation
Additional review to be performed
Hydro Governor Model
PSLF hyg6d model includes the model of the hydro-servo in Kaplan turbines
Model is being shared with PSSE and PowerWorld
Hyg6d is planned to be up for approval at the March 2013 MVWG meeting
Power Plant Model ValidationPower Plant Model Validation
Power Plant Model Validation (PPMV) version 1B using PSLF play-in function is available on the WECC website in the MVWG PPMDTF Documents site
It is encouraged to install more PMUs at power plant point of interconnections

SVC Modeling Efforts successfully validated the generic
SVS models with six SVS installations in North America, including three in WECC

validated PDCI Modeling
Sylmar model still needs to be validatedCelilo is expected to be replaced in 2016, the
