Development of Nonlinear Predictor with a Set of Predicted Points for Continuation Power Flow

Abstract

In this paper, a new continuation power flow method is proposed to speed up computational time for drawing P-V curves in power systems. The continuation power flow calculation aims at successively evaluating power flow solutions in changing the nodal specified value of power flow calculation. The P-V curves are useful for static voltage instability. The conventional continuation power flow calculation methods are based on the predictor-corrector method. This paper proposes a new nonlinear predictor in the predictor-corrector method. The proposed method simultaneously evaluates a set of solutions candidates through the nonlinear predictor. The effectiveness of the proposed method is demonstrated in sample systems.
