... the solution obtained is not optimal for the original district heating system model. The paper presents a methodological approach to determining optimal parameters of district heating systems with several heat sources. The approach employs a modified dynamic programming optimization method that provides an optimal solution without decomposition into the heat source service areas. © 2019 входит Статья в журнале

The mathematical statement of the problem is formulated as the discrete-continuous optimization problem. This statement is based on the proposed methods of representing the network model and its elements. An algorithm based on dynamic programming is proposed, which implements a new approach to setting up the computational procedure and is versatile enough for calculating networks that serve various purposes. The results obtained during real network optimization are presented....

For intrastep simulation, we use the model of extreme intermediate states developed at the Melentiev Energy Systems Institute. To increase the optimal results of calculations when transitioning from one step to another, the dynamic programming method is applied. The properties of reversible processes in the case of constructing trajectories by the second method are always observed by the potentiality of one-dimensional motion. The need for the use and applicability of the ...

The algorithm is based on the dynamic programming principles. It is applied in the software package “Dynamics” that realizes the methods of combinatorial modeling to study the long-term options for the development of energy systems. © 2019, Pleiades Publishing, Ltd. нет

In this case we normally solve a complex non-linear programming problem with discrete and continuous variables. ESI SB RAS proposed effective methods to solve it. A method based on dynamic programming was devised for a tree-like network. For ring-shaped networks, there is a multi-loop optimization method which is based on the principle of successive improvement of the solution. An important feature of these methods lies in the fact ...
