Abstract

Regional integrated energy system (RIES) is an effective way to achieve the goal of energy conservation and emission reduction of the whole energy system, and regional heating network (HN) is an important energy transmission way in the RIES. This paper focuses on the RIES optimal scheduling problem considering HN. Firstly, the RIES structure model with multiple combined cooling heating and power (CCHP) subsystems is established. Secondly, according to the basic principle of energy transmission through pipelines, a general simplified model of HN considering node flow balance and heat flow constraints is established. At the same time, considering the excellent distribution of solutions in the population method and the operability of the robust optimization over time (ROOT) in solving dynamic optimization problems, an improved ROOT based on particle swarm optimization (PSO) is proposed. Finally, an optimal scheduling model with the goal of minimum daily operating cost is established. The simulation results show that the improved ROOT can reduce the RIES operation cost by 4.58 %, and the operating cost of RIES can be reduced by 6.34 % after the HN is configured. Considering the above two measures, the total operating cost of RIES can be reduced by 10.93 %.

考虑供热网络传输模型的区域综合能源系统稳健优化运行策略研究

区域综合能源系统（RIES）是实现整个能源系统节能减排目标的有效途径，而区域供热网络（HN）是区域综合能源系统中重要的能源传输方式。本文主要研究考虑 HN 的 RIES 优化调度问题。首先，建立了多冷热电联供（CCHP）子系统的 RIES 结构模型。其次，根据管道输送能量的基本原理，建立了考虑节点流量平衡和热流约束的 HN 一般简化模型。同时，考虑到种群法中解的良好分布以及时间稳健优化（ROOT）在解决动态优化问题中的可操作性，提出了一种基于粒子群优化（PSO）的改进型 ROOT。最后，建立了以每日运营成本最小为目标的优化调度模型。仿真结果表明，改进的 ROOT 可使 RIES 的运行成本降低 4.58%，配置 HN 后 RIES 的运行成本可降低 6.34%。考虑到上述两项措施，RIES 的总运行成本可降低 10.93%。
