This paper studied the influence of the adding infinity bus imbalance to the objective function to be minimized to solve the problem of the power flow calculations by means of Newton’s method in optimization. Infinity bus influence on the trajectory of pulling the operation point into existence domain was analyzed by means of a range of the test model calculation performing. It is estimated the infinity bus arguments influence on the trajectory of pulling the operation point into existence domain. A thorough analysis of the test calculation results shows the considerable decreasing the influence of the initial estimates accuracy on the steady-state calculations result.
