In order to improve the accuracy and rapidity of the disturbance source location, a new method based on variational mode decomposition (VMD) for forced power oscillation disturbance source location is proposed. Using the active power and frequency of the transient phase of an oscillation, the dominant mode of electrical components is extracted by VMD. Then, the oscillation energy using the variation is calculated to achieve the disturbance source location. Taking the forced power oscillation accident caused by too strong primary frequency modulation as an example, the effectiveness and feasibility of the proposed method is verified.
