摘要:
      能源联供系统具有一次能源利用率高、经济性好等优势,但因其内部设备种类较多、能量流耦合较强而使得规划问题复杂度提高。对于联供系统的规划问题,首先阐明了供能站外部联络结构以及供能站内部的能源联供模式,针对目前新规划地块负荷供区划分和供能站选址困难的现状,提出了综合加权负荷矩指标并将其应用于维诺图,以解决供区划分和供能站选址的难题;综合考虑不同能源网络规划需求的差异,对冷/热/电能源在子供区内的配送网络采用了不同的规划结构;供能站内各类设备的容量与站间冷热电等能源连接网的规划在优化时相互影响,存在着复杂的耦合关系,文中建立了“站内容量—站间网络”联合规划模型,同时对供能站内各类设备容量和供能站间连接网进行优化规划。最后,在某新规划地块的算例中,仿真验证了所述供区划分和供能站选址方法的有效性,最终的联合规划结果验证了该方法的经济性和实用性。
Abstract:
      The energy co-supply system(ECS)has the advantages of high energy efficiency and good economy, but the complexity of the system planning is increased because of the variety of internal equipment and the strong coupling of all kinds of energy flow. For the planning problem of ECS, the external connective structure among power stations and the specific energy co-supply mode in the power station are illustrated firstly. Aiming at the difficulties of area division for energy supply and site location of power station, a comprehensive weighted load torque index is presented and applied to solve those difficulties based on Voronoi diagram. Considering the different requirements of cold/hot/electric energy distribution networks, different structures are adopted for them. There is complex coupling between the equipment capacity in power station and the cold/heat/electric networks among power stations. So the joint planning model of station capacity-station network is established to optimize the equipment capacity in power station and the energy networks among power stations at the same time. Finally, the effectiveness of the proposed method is verified by simulation in a case of a renewable energy supply planning area, and the final joint planning result verifies the economy and practicability of the proposed method.
