    摘要:

    对社区综合能源系统需求侧潜在的大量可控负荷,提出了考虑需求侧可控负荷的含储能社区综合能源系统优化调度模型。首先,分析了综合能源系统的框架并以此建立了包含能源生产、转换、存储等模块的数学模型。其次,根据需求侧电、热可控负荷的响应类型建立了三类负荷响应模型。最后,以社区综合能源系统在一个调度周期内综合运行成本最小为目标,构建考虑可控负荷的社区综合能源系统优化调度模型。通过算例仿真结果表明,可控负荷及储能设备的参与对提高系统经济性具有积极的影响并能有效减小系统负荷的峰谷差值,验证了文中所提模型的合理性。

    Abstract:

    ABSTRACT: Aiming at the potential large number of controllable loads on the demand side of the community integrated energy system, an optimal dispatch model of the community integrated energy system with energy storage considering the demand side controllable load is proposed. First, the framework of the integrated energy system is analyzed and a mathematical model including modules of energy production, conversion, and storage is established. Secondly, three types of load response models are established according to the response types of demand-side electric and thermal controllable loads. Finally, with the goal of minimizing the comprehensive operating cost of the community integrated energy system in a dispatch cycle, an optimal dispatch model of the community integrated energy system considering the controllable load is constructed. The simulation results of calculation examples show that the participation of controllable loads and energy storage equipment has a positive impact on improving system economy and can effectively reduce the peak-to-valley difference of system load, and the rationality of the model proposed in the article is verified.
