A novel approach of three phase unbalanced radial distribution systems modeling for power flow calculations

Abstract EN

A novel approach of three-phase unbalanced radial power distribution systems (URDS) modeling for power flow calculations is presented in this paper.

It solves a simple algebraic recursive expression of voltage magnitude and all the data are stored in vector form.

The algorithm uses basic principles of circuit theory and can be easily implemented.

Mutual coupling between the phases has been included in the mathematical model.

The proposed algorithm has been tested on several practical unbalanced radial power distribution networks.

The results obtained with the proposed methodology on the 8bus and IEEE 13bus unbalanced radial distribution systems are in agreement with that in the literature and show that the proposed model is valid and reliable.
