Abstract:In this paper, some strategies dealing with two main difficulties of Optimal Power Flow Newton approach, i.e. the numerical instability and the identification of binding inequality constraints, are presented. These strategies include: a improved adaptive movement penalty method, a network topology based identification method and a limited times skipping method of trial iteration. The numerical results of several IEEE standard test system and two Chinese real network have shown that these improved strategies play a great role for underpinning the numerical stability, convergence characteristic and computation time saving.
Keywords:optimal power flow  ill condition matrix  trial iteration  movement penalty  network topology
