An Analytical Method of Current Distribution Factors Based on Circuit Theory

This paper proposes a current distribution theory based on classical circuit theory. According to interface power flow, the distribution current from source to branch circuit can be clarified by using current distribution factors through network structure parameter. This method is conducive to economic dispatch and power flow analysis. Besides, this paper proves that kcl of the electricity network is still applicable to every node through using the current distribution factors. It ensures the correctness of the method. Finally, the proposed method is tested on the classical IEEE9-bus system. The results of example show that the algorithm is correct and useful.
