Complex Dissipating Energy Flow Method for Forced Oscillation Source Location [PDF]
IEEE Transactions on Power Systems, 2022 This manuscript was submitted to IEEE Power Engineering Letters. We propose a Complex Dissipating Energy Flow (CDEF) whose projection onto a specific direction, defined from a representative R/X ratio of the system branches, is used to trace sources of Forced Oscillations (FO).
