Abstract: For the planning, operation and design of the modern power systems, the effect of the network reconfiguration of the identified weaker lines are nowadays investigated. Gradually increasing the load, saddle-node bifurcation (SNB) is determined using modified continuation power flow (MCPF) algorithm. Judging three different sets of the security limits, the weaker buses are detected from the power flow solution at the SNB point. The three different reconfigurations are implemented on the identified weaker lines for the standard IEEE-14, 30 and 57-bus test systems separately. The optimal location and the suitable lines for the reconfiguration are demonstrated with the results. Using the network reconfiguration, the significant improvement of the SNB points or load margin, weaker buses, voltage profile, line losses for the different cases are proved showing results.
