要約(日本語): When a generator in a heavily loaded power system reaches its reactive power limit, the system will become immediately unstable at the transcritical bifurcation, i.e., the immediate voltage collapse occurs, which is different from the common static saddle node bifurcation. The load power margins would be misleading if this phenomenon were neglected. In this paper, the Interior Point Method is used to evaluate the load power margins with respect to the transcritical bifurcation associated with the immediate instability. The effectiveness of the proposed method is demonstrated through IEEE 118 bus system.
