摘　　要：针对不同类型灵活性资源调节特性差异对系统运行的影响问题,提出一种考虑灵活性资源多时间尺度协调互济的综合能源系统优化调度策略。首先,从指令响应速度、累积调节范围和调节速率三个角度,对系统内不同能源类别、不同调度环节的灵活性资源所具有的调节特性进行挖掘。其次,考虑气、热能量的传输惯性,对供热区域热惯性以及气、热管网的动态特性进行建模,挖掘气、热能源系统与电力系统协同调度过程中的调节潜力。继而,建立综合能源系统多时间尺度协调调度模型,实现灵活性资源在多时间尺度上的协调互济。最后,通过算例仿真验证了所提调度策略能够在不同时间尺度调度中协调不同调节特性灵活性资源出力的同时,也为短时间尺度的调度预留更大的功率调节空间,更好地响应风功率在不同时间尺度上的随机波动。In this study,an optimal scheduling strategy of an integrated energy system considering the coordination and mutual aid of flexible resources on multiple time scales was proposed to address the issue of the impact of differences in the regulatory characteristics of different types of flexible resources on system operation.First,the regulation characteristics of flexible resources in different energy forms and scheduling links were analyzed from three perspectives:command response speed,cumulative adjustment range,and adjustment rate.Second,considering the transmission inertia of gas and heat energy,the thermal inertia of the heating area and dynamic characteristics of the gas and heat pipe network were modeled.Thus,the regulatory potential of gas and heat energy systems could be exploited in the process of cooperative scheduling with a power system.Subsequently,a multi-timescale coordinated scheduling model of the integrated energy system was established.The coordination and mutual aid of flexible resources on multiple timescales were realized.Finally,the simulation results show that the proposed scheduling strategy can coordinate flexible resources with different regulation characteristics in the scheduling of different timescales,which can reserve more power adjustment space for shorter timescale scheduling to better address the random fluctuations of wind power on different timescales.
