Abstract

One of the modern problems of the energy systems of countries with a post-industrial economy is to ensure their sustainable development in the face of growing uneven energy consumption, which is caused by a decrease in the role of industry in the structure of demand for energy products. In Russia, this problem is exacerbated by a significant share of the combined production of energy products, characterized by low maneuverability and hence is poorly adapted to operating under daily fluctuations in demand for electricity.

This paper considers the problem of increasing the stability of the energy system by optimizing the production structure of thermal power plants and proposes a combinatorial algorithm that allows to draw up a plan for structural and technological modernization of the composition of power equipment taking into account the forecast of growth of uneven electricity consumption. To solve this problem, the authors analyze the change in the structure of demand for combined-production products and its further effect on the efficiency of production of the energy system. The analysis has revealed that structural changes in the demand for energy products lead to the increase in uneven daily consumption. As a result, it leads to inefficient use of the heat-generating aggregates of the power system. The results of the study reveal the necessity to develop an approach to optimize the production structure of the energy system of the regions. When optimizing the production structure, the optimality criterion was used – the utilization factor of power equipment production capacity. With the application of the efficiency criterion, the daily consumption of energy production was estimated based on the type of the heating units used. Based on the evaluation results, an algorithm for optimizing the generation of energy products is compiled; through this algorithm, the principles of dynamic programming are realized.

To support the final results of the study, the authors draw attention to the application of the proposed approach in the preparation of investment programs that will ensure an effective level of capacity utilization.
