Constrained Load Flow Using Recursive Quadratic Programming

The present paper will discuss the efficient, practical and definitive algorithm for dealing with constrained load flow problems. Algorithms based on mathematical programming and algorithms based on the load flow calculation methods have been studied since earlier days. However, on account of numerous control variables to be determined and of inadequate calculating efficiency, the guarantee of unfailing solution is yet to be achieved. In the calculating procedure herein 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 on-line power system operation but also as simulator software for training system operators.
