The MATLAB and Simulink product family from MathWorks provides tools
that support automation and scaling of power plant model validation
(PPMV) to help address technical standards such as NERC MOD 26.

NERC Regulation (MOD 26/27)
Generator/Exciter Modeling & Validation
Challenge: Build a good dynamic model for a
Generator/Excitation System that matches the
actual equipment in the field and validate it
through offline/online testing

Offline Power Plant Testing
Establish a test harness to perform offline
power plant model validation using step
tests or other input data.
Continuously verify your model validation
by using multiple sets of input data to
estimate a single power plant model.
18
Online Power Plant Performance Monitoring
Establish a test harness to perform online
power plant model validation by replaying
synchrophasor data through your
simulation model.
Continuously verify your model validation
by using multiple sets of input data to
estimate a single power plant model.
