    摘要:

    针对智慧能源小区热电耦合系统中能量间纵向转换和用能负荷横向搬移的协同用能优化问题,通过负荷侧需求响应用能精细化建模,提出一种计及需求响应的热电耦合系统用能优化方法。在分析典型热电耦合系统结构框架上,通过用能负荷分类及其用能响应过程的数学建模,建立了含热电耦合系统的能源供给侧与用能负荷侧的能量枢纽方程,实现了用能负荷响应与能源供给之间能量转换的量化描述;其次将用能负荷的需求响应程度表示为可转移负荷参与比和可转换负荷参与比,建立了系统运行成本最小的热电耦合系统用能最优化模型,并提出了灵活尺度多次需求响应参与的模型求解方法。最后,算例结果表明,在高可转移负荷参与比和低可转换负荷参与比时,在降低了供给侧峰值段负荷的同时使系统总成本降低,实现了热电耦合系统用能最优化运行。

    Abstract:

    Aiming at the synergy optimization problem of longitudinal transition between energy and lateral shift of energy consumption for thermoelectric coupling system in smart energy community, this paper proposes an optimization method of energy consumption considering thermoelectric coupling system of demand response through refined modeling of energy consumption for demand response on load side. Based on the analysis of the structure framework of typical thermoelectric coupling system, the energy hub(EH) equation is established between energy supply side, energy consumption on load side containing thermoelectric coupling system by the mathematical modeling of load classification and response process for energy consumption, which realizes the quantitative description of energy conversion between load response of energy consumption and supply. Then, the demand response degree of load for energy consumption is expressed as the participation ratio of the transformable load and the shiftable load, the optimization model of energy consumption is established with the lowest system operation cost. A model solution method is proposed that it can be figured out by flexible scale multiple demand response participation. The results of experiments show that the peak of load in supply side and the total system cost can be reduced at the same time with high shiftable load participation ratio and low transformable load participation ratio which achieves the optimal operation of the thermoelectric coupling system.
