Summary

Currently, the Colombian power system is transitioning to a technology-diverse grid with both synchronous and inverter-based generators (IBRs). This transition introduces new challenges to maintain stability, reliability and quality features. One of these challenges is related to the system’s ability to damp electromechanical oscillations, a function traditionally provided by

Power System Stabilizers (PSSs) in synchronous generators. While Power Oscillation Damping

(POD) has been implemented in power-electronic devices, the Colombian regulatory framework does not define POD requirements for IBRs. This paper reviews POD characteristics and proposes an implementation strategy to damp conventional electromechanical oscillations in the Colombian power system. It outlines an observability-based approach to select POD input signals and uses correlation analysis to quantify how candidate signals affect damping. The findings and proposed actions, based on IBR operational experience, provide guidance that may be transferable to other power systems undergoing an energy transition.
