The present paper considers methods of predicting load losses under varied types of electrical energy loss characteristics. The method of forecasting electrical energy losses with the use of one-factor (planned electrical supply to network) and multi-factor (planned values of electrical supply to network, energy output from electric power stations, etc.) characteristics of power and energy losses is proposed. Static models of nodal loads and parameters of equivalent network are used. The paper substantiates the application of multi-factor characteristics for assessing electrical energy losses during regulatory period. The paper provides the solution of the system of nonlinear equations describing long-term balance plans for electrical energy and gives the results of predicting load losses of electrical energy.

The paper present modes of operation of 10(6) kV distribution networks, which are determined by the loads of consumers. The network scheme is based on an open circuit, which allows you to perform calculations for each 10(6) kV distribution line (feeder) separately. The calculation of power losses in the electric network is carried out by the method of average loads. The paper determines the integral characteristics of the operational parameters of the head branch, determines the parameters of the equivalent power loss of the feeder equivalent circuit, and the equivalent circuit determines the energy loss in the feeder. The paper compiles the equivalent circuit of the considered network section, calculated the parameters of the equivalent circuit elements and determines the total power loss in all linear sections. The paper presents an algorithm for calculating the steady state using the example of a feeder and shows the sequence of calculation of current distribution in the branches of the equivalent circuit.
