Mathematical Modeling of the Heat Energy Market on a Single Heat Supplier Basis

... at the level of average total costs and on the demand basis for industrial consumers. Hydraulic circuit theory models and methods, as well as basic microeconomic provisions, are adopted as a scientific and methodological basis describing the proposed mathematical models. To solve the energy supply and demand equilibrium problem, an algorithm is developed for both energy tariff options based on univariate relaxation using redundant design schemes and simple iteration. The developed mathematical models ...
