摘要：To calculate the static voltage stability critical point, an improved continuation power flow method based on traditional continuation power flow is proposed. Considering the quasi secondary features of PV curves, the proposed algorithm uses the least square method for prediction. Fit a quadratic curve combined with all the power flow solutions known in the calculation process. Through the curve we can get the nonlinear prediction of the critical point of voltage stability. And then by using the local parameters method, construct the parameters equation to obtain the actual power flow solution. The paper also proves the validity and rapidity of the improved method.
