Software and information simulation complex of multi-node integrated and autonomous power and heat supply systems

Abstract

A software and information complex for modeling multi-node integrated and autonomous power and heat supply systems is proposed. The main difference of the proposed software and information complex is the possibility of a detailed consideration of the influence of economic and technological parameters contained in the power system of individual power units and nodes. These parameters can be presented both in the form of matrices on the sheets of the software and information complex, and in the form of separate attached files available for automated input by the software and information complex. The main advantages of the complex, which distinguish it from the known ones, include versatility, which makes it possible to study various models of energy systems in a short time. This versatility is ensured by the fact that the complex is developed using a combination of standard Microsoft Excel software and SolverStudio – an add-in for Excel 2007 and later versions on Windows, which allows you to explore a variety of optimization models using a large list of optimization modeling languages. With the SolverStudio add-in in the information package, the user can develop, edit, save, and debug an optimization model in an Excel workbook. The connection of source data, sets, parameters, constants and variables used in the model is conveniently organized. After editing the parameters and source data, the model is launched. Simulation results can be displayed both on model sheets and displayed as separate files. Another advantage of the software and information complex is the ability to conveniently compare many models, due to the fact that each of the worksheets can have its own model. The developed software and information complex makes it possible to calculate in detail the energy, technological and economic indicators of the optimal use of power system components, to determine the permissible limits of the operating parameters of power units of autonomous and integrated power systems. The results of these calculations make it possible to select appropriate measures for the future renewal of technologies for the production of electric and thermal energy. The ease of use and editing of both individual parameters and program texts used in modeling the development of power systems improves the quality of the resulting development scenarios. The proposed software and information complex can be used to study the prospects for short-term and long-term development of Ukraine, as well as the energy system integrated with the power systems of neighboring ENTSO-E member countries, which is relevant in these conditions.
