    Abstract

    In this study, a novel Enhanced Adaptive Phasor Power Oscillation Damping (EAPPOD) strategy is proposed, which is capable of compensating time-varying data transmission latencies between Phasor Measurement Unit (PMU) sites and the control center, and also mitigating the Low-Frequency Oscillations (LFO) of inter-area signals. The proposed method can handle general communication delay-related problems and fulfill LFO mitigation tasks in modern power systems, and in this study this method is integrated with the Doubly Fed Induction Generator (DFIG) Rotor Side Control (RSC) scheme to achieve the control purpose. The control signal is produced for the purpose of minimizing the amplitude of the phasor component disaggregated from the measured signal, using a novel signal decomposition algorithm. It is then transmitted to the active power regulation scheme in the DFIG RSC structure to modulate the power reference value, so as to realize LFO mitigation. Improving upon the recently established APPOD method, the EAPPOD strategy incorporates a series of integral newly designed methods, including average assignment, phase tracking and magnitude attenuation, to overcome the limitations of the APPOD method operating in varying-latency situations, and consequently to achieve a better LFOD performance. The newly proposed EAPPOD method will thus benefit both online power system monitoring and LFOD enhancement.
