### Abstract

The load flow multiple solution problem is investigated from the point of view that each load flow equation is expressed as a quadratic form in rectanguler coordinates. Using the fact that any two solutions of the multiple solutions can be represented with the middle point and deviation of those, the existence condition for the multiple solutions is shown by structure-determining vectors. By the above investigations, a heuristic algorithm for finding the multiple solutions is developed, and the problem of close multiple solutions is considered. Both results are examplified for the J. B. Ward & H. W. Hale 6-node and the A. Klos & A. Kerner 3-node systems.
