Improved Newton´s Load Flow Through a Minimization Technique

Newton´s method [1] is altered to obtain a faster convergence than with the normal approach. The method is derived by comparison with the non-linear programming approach [2]-[4] to the solution of the load flow problem. A control of the convergence process is an additional feature of the proposed algorithm. By means of this control, the method converges for cases when the normal Newton´s method diverges. Numerical examples show evidence of these characteristics. The alteration is simple to implement on existing Newton programs.
