| Summary: | The purpose of this project is to review and investigate the capability of Continuation Power Flow (CPF) method in assessing the static voltage stability of a network. CPF is a method that being introduced to overcome the singularity problem in conventional Newton-Raphson method. In order to analyse the effect of contingency to the network, two types of contingency categorised as generation outage and line outage being applied. The effect of both types of contingency on Maximum Loading Point (MLP) and Megawatt Margin (MWM) is focused as the indicator of static voltage stability. Simulation results demonstrated that for every condition of the system, the system should be able to provide its MLP and MWM values. A set of ranking based on its severity to the system then being ranked. This will help any electric utility planners and also the operators to plan for the most suitable remedial actions to avoid the system moves toward voltage instability. The ranking has been divided into three categories such Unacceptable, Significant and Acceptable. The study used IEEE 14-Bus and IEEE 30-Bus Test System as the study case and Matlab and Power System Analysis Toolbox (PSAT) as the simulation software. The simulation results on both system has proven that PSAT able to analyse the static voltage stability. |
