摘要：

An index of shedding load allocation considering the reactive power variation and voltage deviation of nodal load is deduced based on the first-order model of induction motor, which denotes physically the equivalent susceptance change of nodal load, reflecting the proportion of induction motor in the nodal load and the influence of load model on the transient voltage stability. It is used to allocate the shedding load to each node and an adaptive load shedding scheme considering the system frequency, load voltage and reactive power response is proposed. The simulative results of IEEE 39-bus system show that, compared with the classical adaptive load shedding scheme, the proposed scheme can better guarantee the voltage and frequency stability of power system after big disturbance. ©, 2015, Electric Power Automation Equipment Press.
