A short review of existing methods for the analysis of fuel and heat supply reliability is presented that substantiates the key approaches to solving the problem of comprehensive analysis of heat supply reliability.

This chapter presents new methods and software system SOSNA intended for the parameter optimization of heat supply systems. They make it possible to calculate large-scale systems which have a complex structure with any set of nodes, sections, and circuits. A new methodological approach to solving the problem of the parameter optimization of the heat supply systems is developed. The approach is based on the multi-level decomposition of the network model, which allows us to proceed from the initial problem to less complex sub-problems of a smaller dimension. New algorithms are developed to numerically solve the parameter optimization problems of heat supply systems: an effective algorithm based on the multi-loop optimization method, which allows us to consider hierarchical creation of the network model in the course of problem solving; a parallel high-speed algorithm based on the dynamic programming method. The new methods and algorithms were used in the software system SOSNA.

Heat Energy Market

The paper is aimed at working out the mathematical models and methods to solve the problems of operation of developing heat supply systems in a competitive market environment. The formation of new principles of functioning in this field is conditioned by the market mechanisms emerging due to the interaction between different owners of heat economy facilities within the single system. Today heat energy markets are represented by a great number of enterprises with different types of ownership that operate heat energy sources and heat networks. It is obvious that such a situation explicitly causes conflicts of interests among the heat energy market participants and unbalances the responsibility for production reliability, heat energy supply efficiency and its quality among the participants of centralized heat supply (heat sources – heat networks - consumers). A reasonable solution to this problem can make it possible to determine optimal conditions for operation of the developing heat energy market, and their implementation can increase technical, economic and energy efficiency of heat energy. These problems are solved by using the methods of hydraulic circuit theory, nonlinear dynamic programming and two level programming. The studies performed allowed the creation of mathematical models and methods for optimal construction of efficient heat supply systems, organization of their operation that ensure the realization of full energy saving potential in the field of heat supply to consumers, taking into account the interests of all participants of the heat energy market.

The procedure of forming a transport (parametric) reserve for heating systems of cities and settlements in cases of increasing line diameters with a constant network configuration is considered. For functioning heat supply systems, the formation of a reserve will ensure uninterrupted and safe operation. Safe operation is supposed to be ensured through analysis and prevention of possible emergency situations. The development of mathematical models of the transport reserve is based on the energy equivalent of subscriber subsystems of heating systems, which distinguishes the obtained mathematical models from existing analogues. To evaluate the impact of parametric optimization results on economic indicators, a computational experiment was conducted. As an object of study, the design scheme of a residential microdistrict was considered. The analysis of the obtained results of the computational experiment proved the operability of the obtained mathematical models of transport reservation for functioning heat supply systems. It is possible to make transport reservation for systems of any sizes and configurations or for the studied fragments of these systems. For practical application, it is of interest to calculate the parametric reserve of individual houses that have autonomous boiler rooms.
