“…The comparison results are hardly surprising: the knowledge of the system model used in the proposed method helps to improve the location results in some cases. It is straightforward to use system model to generate model responses to locate oscillation source, which is also the basic idea for the model‐based approaches in Wang and Sun and Chevalier et al In contrast, the energy‐based method should be praised for requiring only measured responses to locate oscillation source.…”

“…Tang et al, Maslennikov et al, and Feng et al have developed the classic energy‐based method into more robust methods and achieved more detailed location results. A model‐based method which uses effective generator impedance to locate oscillation source is proposed in Chevalier et al It represents a source generator as an effective admittance matrix and an effective current source. Generator current spectrums obtained by the impedance matrix can indicate the presence of oscillation source.…”

Summary In this paper, the problem of locating forced oscillation source at device level is addressed, using unknown input observer (UIO)‐based method to realize oscillation source isolation. Firstly, a linear power system model suitable for oscillation source detection and isolation is derived. Typical oscillation sources, namely, oscillation sources from prime movers and speed governors, excitation systems, are included in the model as unknown inputs. Then, a systematic method using UIOs and fault isolation scheme to locate oscillation source is proposed. Using the disparities between the model responses generated by UIOs and the recorded responses, the proposed method establishes a one‐to‐one relationship between a residual and an oscillation source. The location of oscillation source at device level is accomplished on the basis of the different sensitivities of residuals to oscillation sources from different devices. The detectability of oscillation source and the numerical check are also discussed. The effectiveness of the proposed location method is verified by several simulation examples. The results show that the location of oscillation source by the proposed method is effective and is accurate to control the device that the oscillation source originates from.
