Abstract :
This paper proposes a new continuation power flow method for drawing a P-V curve at a node. The continuation power flow calculation plays a key role to understand the limitation of power flow solutions in varying loads. It is useful for evaluating the critical point of the P-V curve in static voltage stability. However, drawing the P-V curve is time-consuming in large-scale power systems. As a result, a sophisticated technique is required to make the algorithm more efficient in terms of step size and robustness of algorithm. In this paper, a hybrid continuation power flow method of linear and nonlinear predictors is proposed to speed up computational time in drawing the P-V curve. The proposed method is successfully applied to the IEEE 118-node and 300-node systems.
