“…In [31], general formulas were developed for cost accounting, using the "cost distribution ratios" of products and residues, here presented in Equations ( 4) and (5). In Equation (4), y ij is defined as the ratio between the exergy produced by the j-th component and used as a fuel by the i-th unit, E ji , and the total product of the j-th component.…”

Exergoeconomics as a Cost-Accounting Method in Thermal Grids with the Presence of Renewable Energy Producers

Thermal grids are efficient, reliable, and sustainable technologies for satisfying the thermal demands of buildings. The capability to operate at a low temperature allows not only for the integration of heat produced by renewable energy sources but also for the storage of surplus electricity from the grid via “power to heat” technologies. Besides, in the future, heat consumers are expected to behave increasingly as “prosumers”, supplying in some periods heat produced by renewable energy plants on site. In this scenario, it is important to propose a method for the cost allocation among producers connected to the grid. In this regard, this paper proposes Exergoeconomics as a possible tool for rational cost assignment. To show the capabilities of the method, some operating scenarios are compared for a cluster of five buildings of the tertiary sector interconnected by a thermal grid. Based on exergoeconomic indicators, such as the exergy and exergoeconomic unit costs, insights into the cost formation process of the heat consumed by users are provided. Sensitivity analyses of heat unit cost to design and operating variables are also performed. Results show that in the presence of distributed producers, the heat unit cost could be approximately 33% lower than in the case of centralized production, due to the lower amount of irreversibility generated. Capital investment accounts for 20–28% of the heat unit cost.

“…District Heating (DH) networks are widely adopted in Northern, Central, and Eastern Europe [4]. Fahl et al [5] estimated that in Europe DH covers about 25% of residential heating demand. Nowadays, DH systems consist of centralized power stations that supply pressurized hot water or steam via pipes to urban areas [4].…”

The object of the research is central heating points (CTP) in Ukraine. The problem that is being solved in the work is the need to modernize and automate existing CTPs. The importance of the problem is the presence of a large number of CTPs in Ukraine, which require urgent modernization of morally outdated equipment and automation of management of their work modes, which must be carried out in stages without removing them from operational status. The need for modernization and further automation of the existing CTPs in Ukraine is substantiated, which is that this will allow increasing the efficiency of the CTPs through the use of modern technical equipment, software and trained specialists in the automated management of the process of heat supply to consumers. And it will also allow to reduce the cost of heat supply tariffs due to the reduction of non-production costs and to reduce the number of service personnel who manage work modes in manual mode. During the martial law, the timely resolution of problems with high-quality heat supply of the population acquires special importance. The result of the conducted research is a theoretical analysis of the quality work of CTPs in the EU countries, realization of their capabilities and prospects for further use in order to transfer their experience to Ukraine. A theoretical analysis of the number and modern technical equipment of CTPs in Ukraine at the present time was also conducted. As a result of the research conducted on the existing CTPs in Ukraine, a survey of their technical condition was carried out, specific directions for the phased modernization and automation of their equipment were developed and proposed, and additional measures were taken regarding the thermal modernization of main pipelines and modern thermal insulation of buildings and structures. The possibility of practical implementation – step-by-step modernization and automation of the CTP, increasing the technical and technological capabilities of the equipment and reducing the tariffs for heat and water supply for consumers.
