Regularized methods of calculating steady-state operating conditions of electric power systems

摘要

Regularized methods of calculating steady-state operating conditions of power systems are presented. These methods are based on a combination of the diagonal relaxation method with Newton's method, and with linear and nonlinear minimization methods. The proposed methods possess qualitatively better reliability and convergence rate compared with those of the source methods. The regularized methods developed have the convergence rate (in terms of the number of iterations) 2 to 3 times better than that of the source combination methods when solving well-conditioned problems. For poorly conditioned problem this factor can vary from 2 to 7.
