Summary: With large-scale integrations of renewable energy sources, the dynamics of the power systems is becoming more complex in power grids all over the world. Fast dynamic controls and switches that are built into the newer power electronic based energy interfaces are interacting with the traditional power grid controls in unpredictable ways. These complex and non-smooth dynamic mechanisms are impacting on the small-signal and transient stability properties of bulk power systems. This project will focus on the development of novel system identification tools that will use synchronized measurements to derive insight on the input-output properties of power system components. The project will assess which of the internal linear and nonlinear features of the models of specific inverter-based resources can be characterized and estimated using external measurements. For improving adaptive control designs, efficient probing signals will be designed for online estimation of transfer functions. An open-source model identification toolbox will be developed for verifying and validating the dynamic performance of power system components using available synchrophasor measurements.
