| Energy shortage and serious pollution are important factors restricting the development of the world economy today,and the issue of energy conservation and emission reduction has become a strategic issue that has been highly valued at home and abroad.With the development of China’s economy,rural agricultural parks,as large-scale agricultural facilities in China,have also achieved considerable development.However,the rapid development of facility agriculture has led to a rapid increase in its energy consumption,coupled with the characteristics of complex building types and large differences in energy consumption levels in agricultural parks,making agricultural parks have great potential for energy conservation and emission reduction,and have become a hot research topic in energy optimization.In addition,traditional energy supply system only analyze the overall performance of the system through the static characteristics of the equipment during optimal design,lacking analysis of the dynamic characteristics of the equipment,and not taking into account the actual operating mode,resulting in frequent occurrences of building more and using less.Therefore,this article aims at solving the existing problems of excessive energy consumption and low energy utilization in agricultural parks,combining with Thermolib simulation software,starting from the optimization design,operation control,and simulation platform construction of the integrated energy supply system in agricultural parks,through research on intelligent optimization algorithm optimization design,energy consumption simulation simulation,equipment dynamic model analysis,and simulation platform development,in order to achieve the goal of reducing the system cost of agricultural parks Reduce carbon emissions,improve energy utilization,and promote the consumption of renewable energy,thereby achieving energy conservation and emission reduction in agricultural parks.The main research work of this article includes:(1)This article considers the characteristics and industrial advantages of rural agricultural park scenery resources and biomass resource endowment,and designs a new type of comprehensive energy supply system for agricultural parks;At the same time,Thermolib thermodynamic simulation software is used to simulate and analyze the thermal equipment in the integrated energy supply system of agricultural parks,and a steady-state model is established.Based on this,the dynamic and steady-state characteristics of the thermal equipment in its thermodynamic library are analyzed.(2)On the basis of comprehensive consideration of government subsidy policies such as surplus grid access and demand response in agricultural parks,a integrated energy supply system integrated optimization design method is proposed.The optimization design is divided into two levels: upper and lower.The upper level optimizes the capacity of system equipment with the goal of economy and environmental protection,and feeds back the capacity optimization results to the lower level as optimization constraints;The lower level also optimizes the operation and scheduling of system equipment with the optimization goals of economy and environmental friendliness,and feeds back the optimized system operation costs from the lower level to the upper level,achieving interactive feedback between the two,thus forming an integrated optimization design.(3)A simulation platform for the integrated energy supply system of agricultural parks was built using Thermolib simulation software.Four different operating schemes for the integrated energy supply system of agricultural parks were proposed,including "integrated optimization design+operation optimization","integrated optimization design+following thermal load","following thermal load+operation optimization",and "following thermal load+following thermal load".The schemes were compared on the simulation platform,and through the simulation platform of the integrated energy supply system in the agricultural park,analyze the changes in operating conditions of the system equipment during operation,and analyze its dynamic characteristics.(4)The research in this paper is applied to a large rural agricultural park,and the integrated energy supply system simulation platform of the agricultural park is used to compare various operation schemes,to verify the progressiveness of the integrated optimization design method;At the same time,during the comparison of various schemes,the operating conditions of each equipment are monitored through the simulation platform of the integrated energy supply system in the agricultural park,and the dynamic characteristics of each equipment are analyzed. |
