Abstract

The classical constant-power load model is usually employed for load flow analysis. Since the actual loads of power systems mostly have nonlinear voltage-dependent characteristics, integration of nonlinear load models into load flow algorithm is essential to get better and accurate results of load flow analysis. In
this paper, the conventional load flow algorithm is modified to incorporate the nonlinear model of induction motor load. The algorithm efficiency of the modified load flow has been investigated using the IEEE-30bus
standard system. The results show that the induction motor loads have significant impacts on convergence characteristics of active and reactive power mismatches of the modified load flow.
