In this paper, simple approximate formulas
are established to estimate active and reactive power losses in distribution
networks. The developed formulas based on load profiles are derived from
Elgerd’s power loss formulas. A simple model is also proposed to estimate the
load profile while considering several parameters, such as the average load
demand and the load limitations. Derivation of the load model and the loss
formulas are presented along with their applications on two distribution
networks. The results show that the loss formulas, which depend on the proposed
load profile, can estimate the power losses in distribution networks with high
precision.
