Abstract

The close relation between voltage instability point and loading limit is well
known, thus the calculation of loading provides some information about VOLTAGE STABILITY.
Unfortunately, power system load flows diverge at or near singular solutions. In this paper, a
new method is proposed to overcome this convergence problem by using a transforming
parameter. This method stems from the bifurcation theory. The emphasis is on the saddlenode
bifurcation that sometimes occur in power systems. In addition, based on the proposed
method, a computational algorithm is developed to determine voltage-parameter curves. To
analyze voltage problems such as voltage collapse, this procedure is utilized to determine
loading limit and calculate VOLTAGE STABILITY indexes. The developed techniques have some
advantages such as the use of classic power flow equations with no increase in their
dimension and enlarging the convergence domain by LOCAL ELIMINATION OF SINGULARITY.
