Energy Efficiency of Combined Autunomous Energy Supply Systems Based on Ground Source Polygeneration Plants in the Conditions of the Extreme Continental Climate of Kazakhstan

摘要

In recent years, an interest in autonomous energy generation among consumers in rural, remote and difficult to access areas has been growing in Kazakhstan. One of the ways to provide modern energy services is the creation of energy efficient and reliable local energy systems based on combined generation of energy. In this study, we propose a new structure of energy-generating equipment adapted to the extreme continental climate a ground source polygeneration plant. The proposed structure makes it possible to exclude the direct combustion of fuel and provides a high energy efficiency of heat, cold and electric energy generation in conditions of significant load irregularities throughout the year. A mathematical model for calculation of the energy performance of ground source polygeneration plant in real conditions is presented and specialized software as a tool for designing autonomous systems of energy supply on the basis of GSPP was developed. For configuring and calibrating of the mathematical model, the results of experimental studies of the experimental plant created by the researcher in Almaty University of Power Engineering and Telecommunications were used.
