System of Integrated Energy Supply of Separate Facilities from Renewable Energy Sources

Abstract

KEY WORDS: integrated power supply of separate facilities, renewable energy sources, alternative energy ABSTRACT:The relevancy of the study is due to low efficiency of using solar and geothermal energy in the existing process schemes. In this regard, this article is aimed at revealing the possibilities of using solar and geothermal energy for the integrated energy supply of separate facilities from renewable energy sources. The mathematical simulation method based on the theory of graphs of energy system operation, which makes it possible to analyze the efficiency of the integrated use of solar and geothermal energies for the heat-cold supply of separate facilities, is the main approach to studying this problem. Energy consumption throughout the year and the emergency energy source capacity in "peak" modes were determined based on the developed mathematical model of managing the system of integrated power supply of separate facilities from renewable energy sources plotted with the use of the theory of graphs. The article materials are of practical value for the designers of the systems of integrated heat-cold supply of separate facilities.

Synthesis of modeling and optimal management of smart grids

“…A hybrid system, as illustrated in Figure 3, incorporates renewable energy sources into an electrical system, involving more than one energy source, with at least one being renewable. This hybrid system may also incorporate a storage device [13][14][15][16][17]. The efficiency of a hybrid system depends on many fundamental factors.…”
