Estimation of the Efficiency of Operating Modes of a Cogeneration GTU Operating in Climatic Zones with Temperate Continental Climate and Sharply Continental Climate with Uncertainty of Prices for Energy Products
The authors assessed the efficiency of the operation modes of a cogeneration gas turbine unit during operation in climatic zones with temperate continental climate and sharply continental climate with an uncertainty in prices for energy products. The authors' methodology makes it possible to carry out optimization studies of the operating modes of a cogeneration gas turbine unit, taking into account the determination of the dependence of changes in the prices of electric and thermal energy. The technique allows you to find a price range, on the basis of which a Pareto-optimal set of decisions is built. This will help determine the options for technical solutions and ensure the competitiveness of the gas turbine unit with other heat and power generating plants and choose the most efficient of these options. This helps to determine the options for technical solutions and to ensure the competitiveness of the gas turbine unit with other heat and power generating units and to choose the most efficient of these options. To determine the maximum and minimum boundaries of the heat price range, two optimization problems are solved: the problem of minimizing the energy price to determine the maximum heat price and the problem of minimizing the exergy price to find the minimum boundary of the heat price range. The problem of minimizing the price of electricity is solved for a given heat price and rate of return on investment for constructing a Pareto-optimal set of solutions for the obtained price range. The data obtained can be used to select the optimal technical solutions for operation in regions with different climatic characteristics, to select the optimal combination of circuit-parametric solutions that ensure the competitiveness of the products of this cogeneration gas turbine unit.
