A modal analysis based on reactive power compensation on 6-bus Oman electrical grid

This paper covers the modal analysis application (MATLAB 2019a) for improving voltage profiles by optimum positioning of capacitor banks 6-bus Oman Electrical System because electricity TransmissionCompany (OETC) is suffering drop in these 6 buses especially during summer season as a peak period. The Newton-Raphson (N-R) method will help to determine required reactive power each load bus and well ideal position or point capacitors. process aims maintain Q-V relations electrical grid correlating lowest Eigen-values related Eigen-vectors obtained Jacobian matrix. It depends on Eigen-values, if they are positive then system’s stable otherwise it not stable. In system, potential collapse could be anticipated checking participation factors group minimal Eigen-values. general, critical weak associated with lowerEigen-values. system attributable weakest network avoided determining providing at suitable locations which lead improve stability margin.
