Application Research Of Distributed Energy System Based On Gas And Solar Energy And GSHP

The progress of The Times is based on energy.Since the 21 st century,The demand on the energy environment have significantly changed,and the way to solve the energy environment problem effectively becomes the key of human development.As a kind of energy utilization form which can effectively solve energy environmental problems,the distributed energy system gradually becomes an important direction for the future energy development of all countries.This paper establishes a kind of multi-energy complementary distributed energy systems,which use the micro-gas turbine generator set as the main equipment,and supplemented by Solar thermal system and GSHP(ground source heat pump)system,to increase the proportion of renewable energy in energy consumption and improve the overall energy utilization.The main work of this article is as follows:1)Aiming at analysed the different forms of various distributed energy systems in detail,and introduced the basic concept and the typical process flow of multi-energy complementary distributed energy systems,detailed expounds its main characteristics,determined the multi-energy complementary distributed energy system has many advantages,such as multi-energy coordination,complementary advantages and so on.2)This paper introduced the principle of equipment configuration of multi-energy complementary distributed energy system briefly,and analyzed the evaluation indexes of multi-energy complementary distributed energy system from three aspects,which is energy utilization,environmental performance and technology economy.And proposed a comprehensive performance evaluati on index based on weighted average principle,which provides a more accurate basis for the equipment configuration,performance evaluation and operation optimization of the multi-energy complementary distributed energy system.3)By using the DeST software,this paper simulates a centralized apartment with a nearby general hospital in Zhengzhou,obtained a hourly load data of cooling and heating power load.According to the data,the distributed energy system was built,and not only determined the design and selection scheme of the main equipment but also the system construction scheme.Analyzed the energy saving,technical economy and environmental protection of the system.4)Based on the original distributed energy system,coupling GSHP(ground source heat pump)system,constructed a multi-energy complementary distributed energy system,and analyzed the energy saving,technical economy and environmental protection of the system.Compared with the original distributed energy system,the coupling system has poor economical,but it has better energy conservation and environmental protection,and it's comprehensive performance is also better.
