Newton-homotopy Algorithm of Ⅲ-conditioned Load-flow

摘要：

　　The ill-condition of the load-flow is caused by a variety of reasons.Among them,heavy load and a long line of radiation type slip(large r/x) are the two important reasons.In connection with the ill-conditon above,Newton-homotopy algorithm is introduced in this paper.The algorithm mixes the locally quadratic convergence of Newton-raphison with wide range convergence of homopoty algorithm,so it improves the ill-condition of Jacobian matrix in the process of load-flow calculating,and speeds the convergence.Finally,several examples show the efficiency of the algorithm.
