摘要

通过需求响应计划和建筑用能的灵活调度增强电网稳定性和供需平衡。基于一栋小型办公建筑的光伏发电、储能设备及地源热泵系统进行用能调度策略的设计,引入两个参数量化建筑柔性用能潜力,根据最大化光伏利用率、优先满足用户刚需、电价低谷时段储能这3个优先级原则开发一个建筑用能管理模块。在TRNSYS中应用该模块建立有用能调度策略的案例3,并与两个参考案例进行对比分析。结果表明,在一个供暖季节内,系统运行成本分别减少了65.4%、56.7%;地源热泵机组运行COP平均值从3.97提高到4.22;建筑日平均负荷转移率高达51.38%。在峰谷电价的市场机制下,对挖掘建筑柔性用能潜力、激励用户采用需求响应计划和提高电网稳定性具有重大意义。

Abstract

Enhancing grid stability and supply-demand balance through demand response programs and flexible dispatch of building energy use. The energy-use scheduling strategy is designed based on the photovoltaic （PV) power generation, energy storage equipment, and ground source heat pump （GSHP) system of a small office building. Two parameters are introduced to quantify the potential of flexible energy use in the building, and a building energy-use management module is developed based on the three prioritized principles of maximizing the PV utilization, prioritizing the user's immediate needs, and storing energy at the time of low electricity price. The module is applied in TRNSYS to build a case 3 with a useful energy scheduling strategy in comparison with two reference cases. The results show that the system operating costs are reduced by 65.4% and 56.7%, respectively, within one heating season; the average value of COP for the operation of the ground source heat pump unit is increased from 3.97 to 4.22; and the average daily load transfer rate of the building is as high as 51.38%. Under the market mechanism of peak and valley tariffs, it is of great significance to tap the potential of flexible energy use in buildings, incentivize users to adopt demand response programs and improve grid stability.
