Graphical information based power flow algorithm for radial distribution networks

الملخص EN

An efficient load flow solution method for radial distribution network is presented in this paper.

The directed graph of a radial network shows power drawn and path of power flow from the reference node to the leaf end.

A simple technique is used to sort input data and based on network graphical information power flow equations are formulated in matrix form to satisfy the need of distribution automation.

In the algorithm input data are arranged to obtain sorted power injections, losses, branch currents and complex voltages using the novel equations.

The ordered form of collection of input data and formulation of load flow information matrix are found to be excellent convergent over conventional methods.

The methodology proposed here has been successfully demonstrated on an IEEE 15-Node network.

The test results obtained are validated through MATLAB Ver.

7.0.

The proposed method presented in the paper is found to be flexible and efficient.
