System Identification Tools for Power Systems Using Synchronized Measurements

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. » More ...

Nonlinear Analysis of Power System Oscillations using Models and Measurements

With the growth of renewable energy sources, the transmission flow patterns are changing in power grids all over the world. Moreover, fast dynamic devices that are built into the newer power electronic based energy interfaces and advanced control systems are interacting with the traditional power grid controls in unknown ways. These complex and nonlinear dynamic mechanisms are impacting on the small-signal and transient stability properties of the power system. This project will focus on the study of nonlinear phenomena in the presence of poorly damped oscillatory modes for understanding the impact of the nonlinearities on transient stability properties » More ...

Source Analysis of Forced Oscillation Mechanisms

In this project, we will develop the theory and computational tools for a) analyzing and identifying the source of forced oscillations in a best-case scenario assuming full availability of dynamic models and measurements, and b) gradually reducing the availability of model and measurement information in the formulation toward developing realistic source location algorithms which can be implemented in the near future. » More ...
