PV- Curve Analysis of 3 Bus Power System using Matlab

Abstract: P-V curve analysis is use to determine voltage stability of power system network. Newton-Raphson method is used for load flow analysis. In this paper P-V curve is drawn for different load power factor condition. Newton-Raphson method along with determinant of power flow Jacobian matrix helps in calculating loadability limit and critical voltage collapse point at selected load bus. Results were obtained using MATLAB applications software. Keywords: PV Curve, Voltage Stability, Singularity of Jacobian, Power Transfer.
