Abstract To eliminate the cascading overload caused by power flow transferring,a multi control-node emergency control strategy based on DC power flow and virtual bus is put forward.The sensitivity of the balancing machineis firstly calculated by GSDF and GGDF in the DC power flow model.Then the balancing machine participates in the emergency control.According to the characteristics of GSDF and GGDF,different types of control-node sets utilize different sensitivity parameters.The network topology of the power system is divided into generalized power flow transferring zones by graph theory.The nodes outside of the zone and the zone connection cut point are proved to have the same GSDF with the lines inside of the zone.Then the outside nodes and the zone connection cut point are the equivalent to the virtual bus,which simplifies the computational area from the total network to the generalized power flow transferring zone with the overload lines.When the control-node set selected by comprehensive sensitivity exacerbates the overload degree of few overload lines,the multi control-nodes can effectively avoid the situation.Considering the redundant power of normal lines,the reverse equivalence adjustment method and the round-trip power prediction method are utilized to determine the adjustment power,which avoids the power flow verification and improve the emergency control speed.The validity and superiority of the method are verified in the IEEE39 bus system.

Key words： Power system cascading overload trips DC power flow virtual bus multi control-node
