Automation tools for the verification and validation of transient stability models

In light of some major disturbances in the Western Interconnection over the past two decades, efforts are being made to improve the representation of the system to help prevent the underutilization or overutilization of the grid. Various transient stability software packages are widely used for dynamic analyses to help make key decisions in the planning, design, and operation of the power grid. Prior work and software documentation has shown that software packages implement the same dynamic models differently, which can lead to discrepancies in the simulation results of the same system. Dynamic models associated with the generator, such as the machine model, exciter, governor, and stabilizer, play a significant role in a system's dynamic response. However, in a large system, generator interface signals are affected by many other components of the system. To isolate the response of a generator, a single-machine infinite bus (SMIB) equivalent of a generator is created and its dynamic models are analyzed in detail to identify the source of the discrepancies. This research focuses on improving previous work by creating a graphical user interface (GUI) to automate the simulation and analysis of dynamic models in the SMIB generator equivalents. Once discrepancies in the implementation of models between the software packages are addressed, the PowerWorld simulations are validated against phasor measurement unit (PMU) data collected during a disturbance. This research focuses on the beginning stages of this effort by creating a graphical user interface (GUI) to automate the formation of validation base cases by mapping generator dynamic models from planning cases to real-time cases.
