Abstract
Increasing the energy efficiency of electricity distribution networks is the commitment of all national and private electricity distribution companies. One of the basic goals is to reduce losses in electricity distribution networks. It is known that losses in the distribution network can be defined as the differences between taken and delivered electricity. Determining losses has several basic tasks. The first task is to determine the difference between the calculated losses and the actual losses, and to determine the reason for this difference and to determine the necessary guidelines for taking measures to reduce losses. The second task is to estimate the loss index for planning and formulating different plans. This paper presents a new approach to reduce the error between calculated and actual losses using a new method based on the Three Mode method. The main purpose of the study was to investigate the power losses in distribution area. The method proposed in this paper significantly reduces the error compared to the classical Three modes method, which is the original contribution of this paper.
