Non-Minimum-Phase Dynamics in the Electric Power Transmission Network: Identification, Analysis, and Preserving Model Reduction (S-68G)

Summary Implementation of synchrophasors and integration of power electronics are enabling a wide range of controls for managing oscillations and transients in power grids all over the world using diverse feedback control mechanisms. The evaluation and design of these controls requires understanding input-output processes in the network. Over the years, evidence has accumulated that some input-output transfer functions in the power system are non-minimum-phase (i.e., involve right-half-plane zeros), which may significantly complicate control designs. This project will carry out a systematic study of the presence, analysis and handling of non-minimum phase behavior in the power grid models towards facilitating effective future control designs.
