A Data Center Distributed Energy Systems And Economic Analysis Of Energy Efficiency

In energy conservation and emissions reduction,energy intensive and increase energy efficiency policy context,such as distributed energy become a new trend of comprehensive utilization of energy,also contributed to the distributed energy technology unceasing innovation.Distributed energy the energy body can provide electricity for area for user facilities,cold,heat,electricity and other energy,achieve the integrated configuration and optimization of the energy.At the application level,the advantages of distributed energy has a relatively low one-time investment,high energy efficiency and reliable system convenient maintenance,etc.Can provide users with a good economic benefit of high quality energy supply.The load characteristics and energy usage characteristics of data center are analyzed,and the energy security problem of data center is analyzed.The energy supply conditions of the research project are analyzed,including the supply of electric energy,natural gas.cold source and heat sources.On the basis of the analysis of energy supply conditions,the energy supply scheme is compared and the energy supply scheme is determined.The data center is characterized by large power consumption,large heat dissipation,high demand for power supply and cold supply.From the analysis of energy demand,the demand of power load in data center is stable,and the cold load should be stable all day of year.The distributed energy system can improve the efficiency of energy utilization according to the energy usage characteristics of data centers.The technology,economy and uncertainty of distributed energy system are analyzed in this paper.According results of calculation and analysis,the investment of the project is greater,followed by the electricity price,and then for the natural gas price and cold price.The paper calculates the annual cost of electric,cold and thermal load,and divides the load into fixed load and variable load.The fixed load can be measured relatively accurately.The main factors that affect the economy are concentrated in the construction of reasonable and refined equipment operation and maintenance,as far as possible through reasonable equipment allocation and technology to achieve energy saving.The data center project adopts the distributed energy system,which can improve the supportability of the energy supply system,and has a high comprehensive utilization rate of energy and a better economic performance.
