Under-frequency load shedding (UFLS) is the last line of defense to prevent large-scale blackouts. The conventional UFLS scheme does not distinguish the location of the disturbance, and adopts the equal amount or equal proportion load shedding to distribute the amount of load shedding indistinctively without considering the effect of fault generator position on frequency recovery. Considering this, this paper proposed a UFLS scheme based on power tracing. Firstly, this paper analyzed the power transmission relationship and obtained the transmission path between generators and loads based on the superposition theorem. Secondly, this paper distributed the amount of load reduction according to flow tracking results of the faulty power supply, and developed a UFLS optimization scheme with targeted load shedding. At last, the verification was performed in the IEEE 39-bus system. The simulation results demonstrate the superiority of this scheme.
