CONSTRAINED LOAD FLOW USING RECURSIVE QUADRATIC PROGRAMMING.

The authors discuss an efficient and practical algorithm for dealing with constrained load flow problems. Algorithms based on mathematical programming and algorithms based on load flow calculation methods have often been previously studied. However, because of numerous control variables to be determined and because of inadequate calculating efficiency, a guarantee of unfailing solution is yet to be achieved. In the calculating procedure described, the extents of adjustments are not determined simultaneously for all the control variables; the control variables considered likely to produce greater adjusting effect are selected one by one and are adjusted successively. This adjustment method, as a consequence, is useful not only for online power system operation but also as simulator software for training system operators.
