A New Ill-conditioned Power Flow Algorithm Considering the Odditional Nodal Powers

The ill-conditioned load flow algorithm is important to power plan and analysis on security, stability in power system. The new ill-conditioned load flow algorithm based on node lopsided powers is proposed by transforming power flow equations to non-linear programming. It has the all-right astringency arose from the beginning value and no feasible solution in the power flow calculating progress and no larger calculating cost by compared to traditionary power flow calculation. The case study is made at IEEE-30 nodes system and the validity is proved. Key-Words: Ill-conditioned load flow; Optimal multiplier; Newdon power flow; Power system; Nonlinear programming;
