摘要

This paper presents a new and computationally efficient load-flow algorithm for ac distribution systems using graphical search technique along with matrix algebra. The proposed algorithm is equally applicable to balanced, unbalanced and meshed distribution systems. In contrast with traditional load-flow methods, the developed technique does not require any LU decomposition or bus admittance matrix. The significant feature of the algorithm lies in the formulation of path impedance matrix and loads beyond branch matrix; once formulated, it will remain unaltered for the entire operation. The reconfiguration of these matrices takes place automatically in accordance with the change in input data. Moreover, by storing all the system data in array/matrix form it hoards enormous computer memory. Because of the aforementioned reasons, the developed technique is computationally potent when applied on large-sized distribution systems. The efficacy of the proposed methodology is tested on various standard test systems. It is evident from the test results that the proposed algorithm is robust and time efficient for any size of distribution network when compared with several other existing load-flow methods.
