Source location of forced oscillations based on bus frequency measurements

Abstract

The paper proposes a technique to locate the source of forced oscillations in power systems. The only requirement is the availability of bus frequency measurements as obtained, for example, from phasor measurement units. The proposed technique is model-agnostic, optimization-free, non-confidential, and independent from the source and the frequency of the forced oscillations. Accuracy and robustness with respect to noise are demonstrated through two examples based on the IEEE 14-bus and New England 39-bus systems, as well as a case study based on a 1,479-bus dynamic model of the all-island Irish transmission system.
