中文摘要:

随着电-气-热综合能源系统（IES）内多类型能源转换设备广泛接入，热网动态特性对系统运行影响日益显著，能源低碳转型战略的实施使得碳排放成为IES运行关注的焦点之一。对此，开展考虑热动态和碳交易的电-气-热IES协调调度研究：首先，针对供热网络进行动稳态建模以分析管道出口端温度变化，并基于动稳态潮流分析研究其时间延迟及虚拟储能特性差异；进一步面向当前碳交易市场发展需求在IES运行中考虑碳交易，构建以系统用能成本、运行成本、碳交易成本及弃风弃光惩罚成本等综合成本最低为目标的电-气-热IES协调调度模型，从多环节挖掘节能减排潜力；最后，以10节点电力系统、17节点天然气系统和30节点热力系统的综合能源系统为例进行仿真分析，结果表明：考虑热动态特性和碳交易的IES多网络耦合协调调度，能量跨时空转移特征明显，通过IES灵活运行显著提升IES对内、对外友好互动性，且有效降低碳排放，实现其能源综合、高效利用目标。

英文摘要:

With the extensive access of multi-type energy conversion equipment in IES, the dynamic characteristics of the heat network have an increasingly significant impact on the operation of the system. The implementation of low-carbon energy transformation strategy makes carbon emission become one of the focuses of IES operation. In this regard, this paper carries out a study on the coordinated scheduling of POWER-gas-thermal IES considering thermal dynamics and carbon trading. First, the steady-state modeling of the heating network is carried out to analyze the temperature change at the outlet of the pipeline, and the time delay and the difference of virtual energy storage characteristics are studied based on the steady-state power flow analysis. To further meet the development needs of the current carbon trading market, carbon trading is considered in the operation of IES, and a coordinated scheduling model of power-gas-heat IES with the lowest comprehensive costs such as system energy consumption cost, operation cost, carbon trading cost and wind and light abandoning punishment cost is built to tap the potential of energy conservation and emission reduction from multiple links. At last, the electric power system, 17 to 10 node gas 30 nodes system and thermal system of integrated energy system as an example for the simulation analysis, the results show that considering the dynamic characteristic and carbon trading network coupled coordination scheduling more IES, energy transfer across time and space characteristics significantly, by running a significant boost IES flexible IES internal and external friendly interactive, and effectively reduce carbon emissions and achieve the comprehensive and efficient use of energy.
