A new formulation and its solution method for a maximum loading point in electric power systems.

摘要

This paper proposes a new efficient formulation and its solution method for a maximum loading point or saddle node bifurcation point in electric power systems. This point, corresponding to a tip of the P(Q)-V curve, is characterized by singularity of the load flow Jacobian. The proposed formulation is of dimension n+1 , instead of 2n+1 in the standard formulation, for n-dimensional load flow equations. The proposed method uses 1-dimensional singularity condition, obtained from a reduction of the standard n+1-dimensional singularity conditions.
