A Low-carbon Planning Method for Distribution Network Considering Multi-station Integration of Energy Station, Substation and Data Center
在“双碳”目标下,多站融合为配电网低碳规划带来了新的机遇。因此,该文提出了一种综合考虑能源站、变电站和数据中心多站融合的配电网低碳规划方法。首先,建立了多站融合框架,并对数据中心能耗与需求响应特性、能源站电-热-冷能源转换过程和变电站余热回收过程进行建模。其次,考虑能源站和配电网电-热耦合关系,建立了多站融合下能源站支撑的配电网低碳规划模型,采用概率期望方法表征光伏出力和负荷的不确定性,并基于交替方向乘子法(alternating direction method of multipliers,ADMM)实现模型求解。最后,基于改进的IEEE-33节点进行算例仿真,结果表明,多站融合与需求响应措施能够显著降低配电网投资成本与运行成本,并减少配电网碳排放。
Abstract
With the "dual-carbon" goal
the multi-station integration opens up new opportunities for low-carbon planning in distribution networks. In this context
this paper presents a low-carbon planning method for distribution networks by integrating energy stations
substations
and data center. First
a multi-station integration framework is developed to model the data center’s electricity-heat-cooling energy consumption and demand response
energy station’s energy conversion processes
and substation’s waste heat recovery. Second
a low-carbon planning model is created based on the electric-thermal energy coupling between the energy station and the distribution network. This model uses probabilistic expectations to address uncertainties in photovoltaic outputs and loads
which the ADMM algorithm solves. Finally
a simulation using the improved IEEE-33 node confirms that multi-station integration
combined with demand response
significantly reduces both investment and operating costs
as well as carbon emissions of distribution network.
