Voltage Stability Investigation of the Nigeria 330KV Interconnected Grid System Using Eigenvalues Method

Journal Title: American journal of Engineering Research - Year 2017, Vol 6, Issue 4

Abstract

Voltage stability investigation of the Nigeria 330kV grid Power Network was carried out using Eigenvalues method. The power system Jacobian matrix was derived using Newton-Raphson power flow solution iterative method to determine the eigenvalues for the voltage stability evaluation of both the existing 28-bus and improved 52-bus Nigeria 330kV power networks. Positive and negative eigenvalues quantifying the power system voltage stability were identified. For a steady state power system, positive and negative eigenvalues showed stable and unstable systems respectively. The eigenvalues voltage stability method was developed, formulated and implemented on the existing 28-bus and proposed improved 52-bus Nigeria 330kV power networks. The various eigenvalues, eigenvectors, participation factors and weak buses contributing to system voltage instability were determined using Matlab/SIMULINK Power System Analysis Toolbox (PSAT) for these power networks.
