In recent years spectral analysis of system response to random load changes has become a standard engineering tool at the Bonneville Power Administration. Analysis of random fluctuations in power on the Pacific AC Intertie has provided information about the influence of system operating conditions upon the effectiveness of Pacific HVDC Intertie modulation, and about dynamic behavior of the western power system generally. This technique has also been used to estimate the required size for a superconducting electromagnetic storage device which will provide backup to HVDC Modulation, and has detected a major system mode 6 months before it was first observed in a transient disturbanceread more

Initial results in electromechanical mode identification from ambient data
TL;DR: In this paper, the authors analyzed field collected ambient noise by solving the Wiener-Hopf linear prediction equations to estimate the modal frequency and damping, and compared the results with results from a Prony analysis on a ringdown resulting from a 1400 MW brake insertion under the same operating conditions as the ambient data.

Application of Prony analysis to the determination of modal content and equivalent models for measured power system response
TL;DR: In this paper, the frequency, damping, strength, and relative phase of the modal components present in a recorded signal are estimated using Prony analysis and a model construction based on response data obtained through large-scale tests of the western US power system.

Performance of Three Mode-Meter Block-Processing Algorithms for Automated Dynamic Stability Assessment
TL;DR: In this article, the performance properties of three mode-estimation block-processing algorithms from the perspective of near real-time automated stability assessment are demonstrated and examined, and issues addressed include: stability assessment requirements, automated subset selecting identified modes; using algorithms in an automated format; data assumptions and quality; and expected algorithm estimation performance.

Identification of Processes in Closed Loop -- Identifiability and Accuracy Aspects
TL;DR: In this paper, it is shown that prediction error identification methods, applied in a direct fashion, will give correct estimates in a number of feedback cases, and that the accuracy is not necessarily worse in the presence of feedback.

Emergence of a New Swing Mode in the Western Power System
R. L. Cresap,J. F. Hauer +1 more
TL;DR: In this paper, the authors show that low frequency synchronizing oscillations between the Pacific Northwest and Pacific Southwest have long been a characteristic of the western power system and that these oscillations are due to a swing mode involving the whole western loop.

TL;DR: The technique relies on the introduction of a pseudo-random binary signal into the system of such low level as to be unnoticeable at the output terminals of the system under test.
