摘要
园区综合能源系统在满足用户冷、热、电等多种能量需求的前提下,可提高系统效益、能源利用效率和可再生能源消纳比例。该文构建基于风光气的园区综合能源系统,并建立燃气轮机精细化数学模型,研究多场景下综合能源系统互补调度特性,得到多目标优化调控方案。结果表明环境温度对燃机性能及综合能源系统的调控方案有较大影响。基于夏季典型日制冷工况和冬季典型日供热工况,以总成本费用最低为目标函数,对燃机、热泵、电锅炉容量进行优化。分别以运行总成本最低和一次能源利用效率最高为目标函数,研究供热和供冷模式下,综合能源系统的优化调控方案。
The park integrated energy system(IES)may improve the system benefit,energy utilization efficiency and the proportion of renewable energy consumption under the premise of meeting the users’various energy demands such as chilling,heat and electricity.The manuscript investigated a park integrated energy system based on wind-solar-gas,and a refined mathematical model of gas turbine was established.The complementation characteristics of IES under multiple scenarios were studied,and a multi-objective optimal regulation scheme was obtained.The environmental temperature has a great influence on the gas turbine performance and the regulation scheme of IES.The capacity of gas turbine,heat pump and electric boiler was optimized with the lowest total cost as the objective function for the typical heating and chilling modes.The optimal regulation schemes of IES under heating and chilling modes are investigated with the objective functions of the lowest total operating cost and the highest primary energy utilization efficiency.
