摘要

综合能源系统(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，文中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的协同优化方法，实现了IES多能源优化时的解耦处理;最后，基于71节点的IES测试系统进行仿真分析，验证了所提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

The integrated energy system(IES)has the characteristic of multi-energy coupling

which can realize the comprehensive utilization and maximize the synergistic effects and complementary benefits among different kinds of energy

such as electricity

heat and natural gas. In this context

this paper proposes a structure of IES to couple electricity

heat and gas. The energy coupling degree and other definitions used for quantitative analysis of the coupling of IES are presented. Besides

an IES optimal operation model using minimum cost as the target is developed

in which the electricity

heat and natural gas network constraints are taken into account. Considering the coupling problem among electricity

heat and natural gas

a collaborative optimization method based on Lagrangian relaxation(LR)is proposed to achieve multi-energy decoupling in the IES optimal operation. Finally

a 71-node IES test system is used to verify the effectiveness of the proposed model and method

and the mapping relationship between the IES optimization results and the system coupling is analyzed quantitatively.
