Maximum power transmission and inadequate voltage control are the two main aspects associated with voltage security analysis. Once critical buses are found by the assessment function, enhancement control actions may recommended. This paper presents a sequential iterative methodology to reinforce system conditions. A 34-bus system is used to show the adequacy and efficiency of the power flow reduction through the "critical branch" of the "most loaded transmission path". Both concepts are introduced in this paper.
