摘要:
      综合能源系统(Integrated Energy System, IES)具有多能耦合的特点,可实现电、热、天然气等能源的综合利用,可以最大化地发挥各能源间的协同作用和互补效益。在此背景下,本文构建了一种耦合电能、热能以及天然气能的IES结构,并给出能源耦合度等定义用于IES系统耦合性的定量分析;建立了以成本为目标的IES优化运行模型,优化模型同时考虑了电、热、天然气网络约束;针对系统运行时的电、热、天然气耦合问题,提出一种基于拉格朗日松弛(Lagrangian relaxation, LR)的协同优化方法,实现了IES多能源优化时解耦处理;最后基于71节点的IES测试系统进行仿真分析,验证了本文所述模型及方法的有效性,并对IES优化结果与系统耦合性的映射关系做了定量分析。
Abstract:
      Integrated Energy System (IES) has the characteristics of multi energy coupling, which can realize the comprehensive utilization and maximize the synergy effects and complementary benefits among different kinds of energy, such as electricity, heat and gas. This paper proposes a structure of IES coupled electricity, heat and gas, and presents the energy coupling degree and other definitions used for quantitative analysis of the coupling of IES. Besides, an IES optimal operation model using minimum cost as target is set up, which considers the electricity, heat and gas network constraints. Considering the coupling problem among electricity, heat and gas, a collaborative optimi-zation method based on Lagrangian relaxation (LR) is addressed, which can achieve multi energy decoupling of the IES optimal operation. Finally, a 71 nodes IES test system is used to verify the validity of the model and method de-scribed in this paper, and the mapping relationship between the IES optimization results and system coupling is ana-lyzed quantitatively in addition.
