Currently, the district heating systems (DHSs) are intensively promoted both nationally and globally. The advantages of using these systems in urban areas compared to individual heating systems are practically indisputable. Still, it is essential that the calculation underlying the assessment of the economic profitability of the projects to connect the new heat consumers to DHS be made correctly by taking into account all the necessary investments and the benefits obtained from the additional amount of energy sale. The article presents the methodology for the optimal regression model selection that can be applied to predict the additional electricity produced in cogeneration mode in case of the new heat consumer connection to the DHS, based on the actual data of the thermal and electrical energy supplied to network from a CHP in the Republic of Moldova. At the same time, it is demonstrated that between the thermal energy supplied to a new consumer connected to DHS and the additional electricity produced in the cogeneration mode, there is a direct and linear correlation. |
