| Abstract |
A solution to the problem of predicting the cost of electricity for an enterprise is proposed, to determine a favorable voltage level. Mathematical models of forecasting with an algorithm for determining the optimal voltage level have been developed, allowing the consumer to independently plan the costs of electric energy (power) and choose an investment-justified technological connection. Variants of application of research results in cyber-physical systems of a smart city are considered. An experimental study was carried out at an operating facility, confirming the practical feasibility and economic efficiency from the application of the forecast of the cost of electricity and technological connection to a cost-effective voltage level. As a result of the experiment, the cost reduction for the purchase of electricity was 12.8%, and the cost of performing the technological connection to the optimal voltage level paid off in 8 months. The study clearly demonstrates the possibility of free-of-charge improvement of the energy efficiency of all energy-consuming facilities (both in Russia and in the world) through the dissemination of information useful to citizens. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG. |
