Weakest bus, most loaded transmission path and critical branch identification for voltage security reinforcement

Maximum power transmission and inadequate voltage control are the two main aspects associated with voltage security analysis. Once weak buses are found by the assessment function, enhancement control actions be may recommended. This paper presents a sequential iterative method to reinforce system conditions. A simple illustrative 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.
