Abstract

The optimization of heat sources in populated areas is associated with the optimization of their structure. The optimization problem is of linear discrete nature and is hard to formalize [1]. The aim of the optimization is to identify the types, sites and mix of equipment of the heat sources. Moreover, this optimization problem is closely related to the scheme and parameter optimization since the equipment mix of heat sources and their connection to existing (newly constructed) consumers determine the heat network configuration. The emerging new trends in the technological development of heating systems require a significant correction of stating and solving typical technical and economic problems to design these systems, which, in turn, predetermines the transition to a new level of their methodological support [2]. The paper proposes a mathematical formulation of the problem of optimal development of heat sources and considers a methodological approach to solving it, including effective load distribution between heat sources, and calculation of the optimal heat network configuration, given the minimum environmental impact of heat sources.

Highlights

  • The optimal expansion of heat sources in the stage of the heating system development implies the selection of sites, types and mix of equipment of the heat sources together with effective load distribution between them, and selection of an optimal configuration of the heat network connecting the heat sources and the consumer

  • One way to solve this problem is to use an optimization method based on joint consideration of all possible combinations of heating system components with a wide variation in capacity, location and number of sources [3, 4], which is as follows: In the first stage, the sites for the heat sources and optimal load distribution between them are sought

  • To solve the problems of the first stage, the methods of structure and parameter optimization, developed in Melentiev Energy Systems Institute SB RAS [5], are applied. They suggest building a redundant scheme of the heat network, creating a redundant set of sites for placement of heat sources and solving the optimization problem

Summary

A methodological approach to optimization of heating systems

The optimal expansion of heat sources in the stage of the heating system development implies the selection of sites, types and mix of equipment of the heat sources together with effective load distribution between them, and selection of an optimal configuration of the heat network connecting the heat sources and the consumer. To solve the problems of the first stage, the methods of structure and parameter optimization, developed in Melentiev Energy Systems Institute SB RAS [5], are applied They suggest building a redundant scheme of the heat network, creating a redundant set of sites for placement of heat sources and solving the optimization problem. This approach is based on three specialized algorithms: MSG to generate maximum structure [11, 12], SSG to generate final structures [11, 13], and ABB to determine the optimal structure [14, 15] using the algorithm of nodes and branches According to this approach, various options for the heat source equipment mix are considered in a single scheme that contains a finite number of components with their possible interconnections. The software implementation based on the joint application of the two above-proposed approaches seems to be effective for the development of an approach to the construction and optimization of redundant schemes of the heat sources structure
