Abstract

This letter presents a novel knowledge-informed deep learning method for the fine-grained localization of forced oscillation sources (FOSs). This method can effectively identify multiple FOSs under anomalous measurements. First, a knowledge-guided block based on dissipated energy flow (DEF) is proposed. In this block, phasor measurement unit (PMU) signals are disassembled and reconstructed in the time-frequency domain to extract DEF knowledge. Subsequently, a spatial-temporal graph attention (ST-GAT) network is employed. Topology information is embedded into this network to capture the spreading patterns of FOSs.
