Abstract

The continuation power flow (CPF) is the most used static voltage stability analysis method, and consists of four steps: prediction, step size control, parameterization and correction, among which parameterization is a key factor to ensure the success of calculating the continuation power flow. In this work, CPF via current injection expressed in polar coordinates and other different configurations are presented for the complete tracing of the P-V curve without problems relating to the singularity of the Jacobian matrix. From the results, all methods are compared with each other and also with the power injection method commonly used for tracing the P-V curve, showing their efficiency.
