摘要:  针对当前综合能源系统(integrated energy system, IES)研究中未详细考虑含电-热-气-冷-汽子系统(power, heat, gas, cooling and steam subsystems, PHGCSS)协调运行效果的现状,研究计及能源子系统关键特征变量的IES日前稳态优化问题。首先,基于多类型负荷需求设计能源集线器(energy hub, EH)及能量耦合方式。在EH基础上提出耦合PHGCSS的能源站模型构架。然后,分别建立IES中PHGCSS稳态数学模型。在考虑峰谷分时电价机制基础上分析蓄电、蓄热、蓄冷对并网运行的IES日前稳态优化的影响。其次,在不同负荷结构下建立含PHGCSS日前稳态非线性优化模型。最后,通过算例分析验证对IES进行稳态优化计算和稳态运行分析的有效性,结果表明,所提模型与方法适用于含PHGCSS的IES日前稳态优化分析及日前动态经济调度,能够合理反映IES的运行特性。

Abstract: In view of the fact that the key characteristic variables of coordinated operation of power, heat, gas, cooling and steam subsystems (PHGCSS) are not fully considered in integrated energy system (IES), optimal day-ahead steady-state analysis of IES considering the key characteristic variables of energy subsystem is studied. Firstly, on the basis of multi-type load demand, energy hub (EH) and energy coupling mode are designed. On the basis of EH, the model architecture of energy station with PHGCSS is proposed. Secondly, the steady-state mathematical models of PHGCSS in IES are developed. On the basis of peak-valley time-of-use power price mechanism, the influence of power storage, heat storage and cooling storage on optimal day-ahead steady state of IES is analyzed. Then, a nonlinear optimization model for day-ahead steady-state IES is proposed under different load structures with PHGCSS. Finally, the numerical case verifies validity of optimal calculation and steady-state operation analysis for IES. The models and methods are suitable for optimal day-ahead steady-state analysis of IES containing PHGCS and dynamic economic dispatch, which can reasonably reflect operation characteristics of IES.
