电气传动 2023年 第53卷 第2期ELECTRIC DRIVE 2023 Vol.53 No.2摘要：为降低规模化养殖业用能成本及碳排水平，提出了考虑围护结构动态特性的低碳养殖场综合能源系统优化调度方法。首先，从“源-网-荷”全环节构建了低碳养殖场的综合能源系统模型，并通过线性化处理以提高求解速度；为了挖掘我国北方冬季养殖场热负荷的灵活性调节能力，建立了牲畜舍围护结构的热动态模型，可在保证牲畜温度舒适度的前提下，通过动态调整流经牲畜舍内散热器的水流量，参与系统运行调度；进而，以养殖场综合能源系统运行成本最小化为目标，构建了养殖场综合能源系统的优化调度模型；采用一个典型养殖场综合能源系统算例对所提方法进行验证。结果表明，基于所提方法得到的优化调度方案可最大限度利用养殖场中的沼气资源进行电能和热能的联合供给，同时通过对养殖场热负荷灵活性的利用可有效降低养殖场综合能源系统的运行成本。关键词：低碳养殖场；综合能源系统；优化调度；散热器；灵活性中图分类号：TM721文献标识码：ADOI：10.19457/j.1001-2095.dqcd24059An Optimal Scheduling Method for Low-carbon Farms Considering Characteristicsof the Livestock HousesCHEN Wanqing1，CHEN Keren1，SHI Pengjia1，JIN Xiaolong2，WANG Huiyuan2（1.

Key Laboratory of Smart Grid ofMinistry of Education，Tianjin University，Tianjin 300072，China）Abstract: To reduce the energy cost and carbon emissions due to the large-scale farming，an optimal schedulingmethod for integrated energy systems（IES）in low-carbon farm considering thermal dynamic characteristics of thelivestock houses was proposed. First，the mathematical models of the integrated energy systems in a low-carbon farmwere formulated from the perspective of "source-network-load"，and the nonlinear models were linearized by certainmathematical methods to speed up the solving process. Second，the thermal dynamics of the livestock house withcontrollable indoor radiators was modeled to explore the ...
