Technical And Economical Comparison Of Distributed Energy System Applications

Energy has become the most important issues for the importance of a common world.As one of the most efficient method to solve the problem of energy utilization,distributed energy resources has been paid high attention and made some achievements and the development of applications by developed countries.China as a country which is lack of source of energy,is now actively engaged in the development of distributed energy.but application of distributed energy resources is still in the exploratory stage in our country,this technology need to vigorously promote and support.The study for distributed energy gas combined cooling,heating and power system in the practical application of H hospital as an example of feasibility analysis.Make technical and economic comparison between gas CCHP(Combined Cooling Heating and Power)system and regular design,find out which is more economic,more reliable and with lower price.Firstly,according to the demand of project,the pattern of cold heat and power was predicted,and the load of the system was analyzed according to the meteorological conditions.Secondly,according to the pattern of the hospital buildings,two internal combustion engines are selected,and the investment cost and operation cost of the project are estimated.Third,analyze the basic components of regular design as ordinary users and estimates the cost of investment and operation.Then campare this design to the gas CCHP system.Through comparison of two schemes of H hospital,we can know that the initial investment cost is the short board of the gas CCHP system,which has its own unique advantages on energy efficiency,safety,and environmental protectio.However,these advantages can only be fully developed in the users who meet certain conditions.Therefore,the development and application of distributed energy need to explore a more flexible and more suitable way for the development of China.
