A New Approach to Calculating Electrical Energy Losses on Power Lines with a New Improved Three-Mode Method

Increasing the energy efficiency of the electricity sector is the commitment of all national transmission operators. One of the main goals is to reduce losses in electrical networks. Electrical networks are one of the most important parts of the electric grid. Delivery reliability and the quality of electricity directly depend on the electrical networks. It is well known that losses in the transmission network can be defined as the difference between the electricity taken and delivered. Determining the losses in overhead power lines has several basic tasks. One task is to determine the difference between calculated losses and actual losses, to determine the reason for the difference between calculated and actual losses, and to present the necessary data for taking measures to reduce losses. The second task is an estimation of the loss index for planning and formulation of various plans. The purpose of this paper is to present a new approach to reduce the difference between calculated and actual losses by modifying the method in three modes, or a new approach to calculating the loss index. The proposed method in this paper significantly reduces the error in relation to the classic three-mode method, which represents the original contribution of this work.
