A flexible current-tracing algorithm in load-tracing in bulk power systems

The acyclic property of complex current digraphs is proved in power systems considering some reasonable hypotheses in this paper. A flexible current-tracing algorithm other than the power-tracing algorithm is then introduced based on the concepts of graph theory. A sparse technique is used in this algorithm, making use of the high sparsity of the involved matrix. IEEE standard 14-bus test system results are presented at the end of this paper to verify the conclusions.
