Play-in time series measurement data with PlayInGen model for Power Plant Model Validation (PPMV)

PlayIn models can be found in the Transient Stability add-on of Simulator. Many dynamic models comprise of differential-algebraic equations that respond to perturbations in a simulation. In contrast, these PlayIn models are used to input time-series data into a transient run at specified time points. In Simulator, a PlayIn Configuration object can be used to store […]
