摘要: 综合需求响应(integrated demand response, IDR)是综合能源系统灵活调度的重要途径,对需求响应负荷、能源生产转换设备进行协同优化有利于提升能源利用率并降低用电用能成本。文章首先分析需求响应负荷特性,将需求响应负荷细分为可中断电负荷、可转移电负荷和可调节热负荷;其次采用能源枢纽建模方法对热电联供(combined heat and power,CHP)系统进行建模,并将多类型需求响应负荷纳入其中;在此基础上,构建考虑多类型需求响应负荷的CHP系统运行策略,以日运行费用与能源消耗量最小为目标对调度模型进行求解;最后,在2种不同场景下对算例进行对比,结果显示:需求响应负荷参与调度,可以实现削峰填谷,使得供需更趋于平衡;通过协调各能源设备及需求侧负荷运行策略,系统的日运行费用节约5.4%,能源转化率提高2.6%,实现了CHP系统的经济优化运行。

Abstract:  Integrated demand response (IDR) has been considered a significant way to raise the flexibility of integrated energy system(IES). By co-optimizing demand response load and energy production conversion equipment, IES will increase the efficiency of energy utilization which in turn lowers the cost of both the energy supplies and consumers. Firstly, the characteristics of demand response load are analyzed, and the demand response load is subdivided into interruptible load, transferable load and adjustable heat load. Secondly, the combined heat power (CHP) system is modeled by the energy hub modeling method, and the demand response load is incorporated into it. On this basis, the operation strategy of the CHP system considering demand response load is constructed. The dispatch model is solved with the goal of minimizing daily operating cost and energy consumption. Finally, the results of case study in two different scenarios show that the participation of demand response load can cut the peak and fill the valley and make the supply and demand more balanced. By coordinating the operation strategy of energy equipment and demand-side load, the daily operation cost of the system is saved by 5.4%, and the energy conversion rate is increased by 2.6%. The economic optimal operation of CHP system is realized.

Key words:  integrated demand response(IDR), demand response load, combined heat and power (CHP) system, energy hub, coordination and optimization
