在"双碳"目标驱动和大规模新能源接入电网的背景下,燃气机组、电转气、热电联产机组等耦合设备的灵活调节能力被逐渐挖掘,这也使得电力、天然气、热力系统的耦合程度逐渐加深,传统的独立调度方式不再适用.实现电-气-热综合能源系统的协同调度,是提高能源利用率和应对新能源不确定性的重要手段.首先分析了三类能源系统在优化调度研究中常用的能流模型及耦合设备建模,然后从电-气-热综合能源系统应对新能源不确定性方法、耦合系统建模、优化求解算法和系统安全域四个方面阐述现有研究进展.最后,对目前电-气-热综合能源系统协同调度研究面临的关键问题进行总结,并对后续综合能源系统协同调度的发展方向进行了展望.
In the context of the"dual carbon"targets and large-scale renewable energy integration,the flexible adjustment capabilities of coupling devices such as gas-fired units,P2G,and combined heat and power units are gradually being explored,which have also enhanced the coupling of power systems,natural gas systems,and district heating systems.Therefore,the traditional independent scheduling mode may not be applicable.The coordinated scheduling of integrated electricity-gas-heat systems(IEGHS)is an important means to improve energy utilization efficiency and respond to the uncertainty of new energy.The commonly used energy flow models and coupled device modeling for three types of energy systems in optimization scheduling research are analyzed.The current research progress is reviewed from the aspects of coping with renewable energy uncertainty,model of coupling system,optimization solution algorithm and security region of IEGHS.Finally,the challenges of the current IEGHS studies are summarized,and an outlook on the direction of subsequent research is given.
