摘　　要：区域综合能源系统冬季供暖期通常受“以热定电”的运行模式制约,区域电网电能调峰能力低,可再生能源利用率低。提出在水源充沛地域引入水源热泵机组,实现热电解耦;同时,结合电制冷机、吸收制冷机、多元储能装置等能量转换设备,形成含水源热泵的区域综合能源系统。构建了各设备机组运行模型并耦合形成系统总体架构,为实现“双碳”目标,综合考虑系统运行经济成本与碳排放成本,建立了区域综合能源系统低碳运行优化模型并给出求解方法。对所提模型及方法进行仿真分析,探讨求解得到的最优运行策略对综合能源系统各方面运行成本的影响,验证了所提模型及运行策略的合理性及有效性。Regional integrated energy systems usually follow the"determining power by heating load"energy-supply principal in winter,resulting in the low load-regulation ability and low renewable energy consumption rate.Water source heat pump units are introduced into areas with abundant water sources to realize thermo-electric decoupling.Combining electric refrigeration devices,absorption refrigeration devices and multi-energy storage devices,a regional integrated energy system with water-source heat pumps is proposed.The overall architecture of this system is constructed by coupling the operation modes of different equipment.To achieve the goals of carbon peaking and carbon neutrality,a low-carbon optimized operation model is proposed on the premise of considering the operation costs and carbon emission costs.Through simulation,the effects of the optimal operation strategy on the operation costs of the integrated energy system at all aspects are studied,which verified the effectiveness of the proposed model and strategy.
