摘要

能量枢纽概念已广泛应用于集成电力、天然气及其他多种异质能源的综合能源系统的数学建模和优化。当多区域互联综合能源系统的基本决策主体转变为多个相互连接且自治运行的能量枢纽时，多个决策主体之间的交互将更为频繁和复杂，对整个综合能源系统进行集中式优化将难以为继。为避免集中式优化方法存在的数据采集量大、模型复杂、与实际运行管理模式不匹配等现实问题，针对多区域电—气互联能源系统的多主体分布自治决策特点，构建了以能量枢纽为基本决策主体的电—气能量流解耦机制，提出了与能量枢纽分布式粒度相适应的多主体协同优化调度模型，并给出了基于交替方向乘子法的分布式求解流程。针对两个耦合能量枢纽的电—气互联能源系统开展的算例测试结果验证了所述方法的有效性和准确性。

Abstract

The concept of energy hub(EH)has been widely applied in the mathematical modeling and optimization of integrated energy systems(IES)with natural gas

electricity and other energy flows. When the decision-maker of a multi-regional IES turns to be multiple interconnected and autonomous EHs

the interaction between multiple decision-makers will be more frequent and complex

which is difficult to centrally optimize the whole IES. To avoid the problems of excessive data requirement

complex models and mismatch of actual operation management mode for centralized optimization method

a coupling mechanism of electricity-gas power flow is established

which takes EH as a basic decision-maker based on the characteristics of multi-agent distribution autonomy decision for multi-regional IES. A dispatching model of multi-agent collaborative optimization is put forward

which is compatible with distributed granularity of EH

and a distributed solution process is given based on alternating direction method of multipliers. The results of the example test aiming at electricity-gas IES with two EHs verify the effectiveness and correctness of the proposed method.
