FAST LOAD FLOW METHOD RETAINING NONLINEARITY.

One of the most recognized load flow methods at present is the N-R (Newton-Raphson) method with sparsity techniques and suboptimal ordering. This paper presents a new load flow method which is several to more than ten times faster than the N-R method and has the same memory requirement, mathematical complexity and accuracy as the N-R method. As an example, the convergence time for 118-bus system was only one eighth of the N-R method. Five and one-half pages of discussion of the paper are appended.
