摘要
针对数据中心高能耗、高碳排放问题,提出了一种风险规避下面向建筑的数据中心综合能源系统低碳规划模型.首先,根据运行特性,建立了数据中心的全生命周期碳排放模型.其次,为解决碳排放计算不精确和可再生能源不确定性带来的风险问题,提出了基于动态碳排放因子的减碳策略和可再生能源间歇性风险度量方法(RIRM),以总成本最低和风险最小为目标函数,对数据中心综合能源系统内设备容量进行最优配置.最后,通过算例仿真验证了所提方法的低碳性和经济性,并将RIRM与条件风险价值(CVaR)进行了比较分析.
Abstract
Aiming at the problem of high energy consumption and high carbon emissions in data centers,a low-carbon planning model for building-oriented integrated energy systems of data centers under risk avoidance is proposed.First,a full life cycle carbon emission model of the data center is established based on operational characteristics.Then,in order to overcome the risk issues of imprecise limitations of carbon emission calculations and indeterminacy of renewable energy,a carbon reduction strategy based on dynamic carbon emission factors and RIRM method are proposed,with the lowest total cost and the lowest risk as the objective function,and the data center integrated energy system is optimally configure the equipment capacity.Finally,the low-carbon nature and economy of the proposed method were verified through numerical examples,and the proposed RIRM method is analyzed and compared with CVaR.
