Minimization methods for solving steady-state condition equations for an electrical power system

Recommendations are given for increasing the computation effectiveness of minimization methods when solving electrical power system steady-state condition problems, i.e. application of a Cartesian system of coordinates which reduces the complexity of computation of minimization methods and increases the efficiency, scaling of linkage functions for PU-type busbars and of the target function, and application of computation with double precision to exclude the influence of computer rounding errors on the convergence of the minimization methods used for computation.
