The Russian Federation has a large territory, which is located in different climatic and zones. There are settlements, which are situated at a considerable distance from each other, in remote areas, given the shortage of basic vital natural resources, such as water, food, and energy. Such regions are located in the Far North, the total area of which is 70% of the entire territory of Russia. These regions are characterized by low population density, lack of fertile soils, inaccessibility of water sources and minerals. 8% of the country's population live and work in these conditions.
An important issue for the people of these regions with harsh living conditions is to find practical solutions to the problems of supply of the population and industry with the necessary resources.
This paper discusses the issue of optimizing the distribution of heat energy and hot water from the supplier to consumers in a decentralized heat supply using P-Graph tools.
The P-Graph software makes it possible to evaluate and compare many options for providing consumers with energy resources and water, taking into account characteristics of the required final product, conditions of remoteness from stations, etc. With the help of P-graph methodology, it is possible to optimize the diagram of supplying energy, water sources to the consumer, minimizing operating costs and negative environmental impact. The P-Graph graphical environment is used to find the optimal structure and 4 algorithms to determine the designs with the lowest operating costs, the most profitable system without taking into account and taking into account the boundary working conditions, the maximum work structure generation.
Two search algorithms were selected to optimize the diagram structure, which determines the less costly options with the most significant profit when supplying consumers with resources, taking into account the harmful effects on the environment. A separate item specifies emission of carbon oxides, CO2 and SO2 the sulfur oxides into the atmosphere. Taking into account the environmental impact in the search for the optimal structure of the resource allocation scheme from sources to consumers allows for a comprehensive assessment of all types of costs at each stage: extraction, transformation, delivery of the final resource to the consumer.
In this paper, the diagram of the distribution of heat energy and hot water flows on the example of sources and consumers of the Tomsk district of the Tomsk region is considered. The structure consists of thermal power plants and individual boiler plants burning coal, natural gas, fuel oil, timber products, etc., and consumers, such as residential sector, communal services and industrial sectors. Some consumers irretrievably consume thermal energy, other return the heating system water back to heating.
As a result of the calculation, the most optimal structure for the generation and distribution of flows of heat energy and hot water from sources to consumers was selected, taking into account savings and minimization of negative environmental impact.
