Simulation And Economic Analysis Of Integrated Energy System Based On The Coupling Of Solar Energy And Biomass

Large scale use of renewable energy can effectively reduce the use of fossil fuels.In this paper,a modern comprehensive intelligent green farm in China is taken as the research object.A comprehensive energy system model is established by using ebsilon software,which is coupled with solar energy and biomass energy.After solar energy heating,circulating water drives biogas,after purification and purification,it enters into micro gas turbine for combustion and power generation.High temperature flue gas drives LiBr absorption chiller to generate cooling capacity,and after utilization The flue gas from the waste heat recovery unit is used to heat domestic water.In this paper,the thermodynamic analysis of the system is carried out,and the influence of key factors on the comprehensive energy system is further studied.The main contents are as follows:First of all,based on the analysis of thermal system,a model of integrated energy system with solar energy and biomass energy complementary was established in a modern integrated smart green farm in China.The performance of the system was simulated by ebsilon software,and the accuracy of the model calculation was verified under the design condition.Secondly,based on ebsilon software,the performance analysis of solar energy and biomass energy complementary integrated energy system is carried out.On the one hand,analyze the energy flow and exergy flow loss of the system,so as to facilitate the subsequent improvement and improvement of the system;on the other hand,study the impact of key factors(environmental temperature,sunshine radiation,air-fuel ratio at the entrance of micro gas turbine,etc.),key processes(solar energy collection,constant temperature anaerobic fermentation of biomass,micro gas turbine power generation,LiBr absorption refrigerator)on the system Influence,simulate key factors and key processes,and draw corresponding conclusions.In addition,the whole life cycle of solar energy and biomass energy complementary comprehensive energy system is evaluated from two aspects of technology evaluation and environmental evaluation,and it is concluded that the system has certain benefits in energy conservation and emission reduction when it is running.
