  "textContent": "The present application proposes a method of locating oscillation sources of wind power integrated system based on energy spectrums. The method include: collecting information of voltage and current at the terminal of each generator and obtaining a dynamic energy curve of each generator over time; choosing the generators whose curve shows an upward trend in the dynamic energy over time curve into alternative generators; obtaining and processing energy spectrums of synchronous generator, DFIG with PLL, and/or an analogical energy spectrum of DFIG with virtual inertia among the alternative generators; selecting generator with maximum proportion of dominant oscillation mode as an oscillation source reference generator; and Calculating the similarity coefficients between energy spectrums of each remaining candidate generator and the oscillation source reference generator, determining the oscillation source generators.",
