The article considers the issue of increasing the energy efficiency of street lighting networks by optimizing of parameters of their elements, the supply conductor section and the number of luminaires in the street lighting network. A substitution circuit for the street lighting network and its mathematical model based on the graphoanalytical method for calculating regime parameters are proposed. The problem of optimizing the configuration of the lighting network is formulated, and its boundary conditions defined by regulatory documents are formalized. As the optimization criteria, the criteria for minimizing the capital and operating costs and maximizing the illuminated area are proposed. To solve the task of finding the optimal balance between minimizing the costs of building and operating a lighting network and maximizing the illuminated area, the research group proposed the method of scalarization that makes it possible to reduce heterogeneous criteria to one supercriteria by normalization and convolution. An algorithm is proposed for the formation of alternative lighting network options taking into account the boundary conditions specified by regulatory documents with the help of which alternatives to the lighting network for different conductor sections were formed, the values of the optimization criteria for each of the variants were calculated. The analysis of the obtained results showed that for the considered problem it is necessary to use the multiplicative convolution of the criteria. The developed approach allows us to solve the problem of determining the optimum section of the conductor of the lighting network with a certain number of luminaires, and also the inverse problem of finding the optimum number of luminaires in a street lighting network for a given section conductor. It is noted that the proposed algorithm can also be used to select the optimal luminaires, supports and other elements of the street lighting network, taking into account the characteristics of these elements in the optimization criteria.
