Multi-time scale low carbon operation integrated energy system considering multiple integrated demand responses

为挖掘需求侧资源响应潜力,文中提出一种计及多重需求响应的综合能源系统(integrated energy system,IES)多时间尺度低碳调度策略。首先,考虑到需求侧资源在不同时间尺度下的响应差异性,建立计及价格型和激励型的多重综合需求响应(integrated demand response,IDR)模型。然后,为减少源、荷预测误差对IES运行的影响,分别构建日前低碳经济调度模型和日内双时间尺度滚动优化平抑模型。最后,算例仿真设置不同场景进行对比分析。结果表明,相比传统IDR,多重IDR能有效挖掘用户响应潜力,提升系统经济性。此外,计及多重IDR的多时间尺度调度策略能有效缓解源、荷误差带来的功率波动并降低系统碳排放量,实现IES低碳、经济和稳定运行。

In order to tap the response potential of demand-side resources,a multi-time scale low carbon scheduling strategy for the integrated energy system(IES)with multiple demand responses is proposed.First of all,considering the difference in response of demand-side resources at different time scales,a multiple integrated demand response(IDR)model considering price and incentive is established.Secondly,in order to reduce the impact of source and load forecasting errors on the operation of IES,the day-ahead low carbon economic scheduling model and the intra-day double-time-scale rolling optimization flattening model are constructed respectively.Finally,different scenarios are set up for comparative analysis in the simulation of a numerical example.The results show that compared with traditional IDR,the multiple IDR can effectively tap user response potential and improve system economy.In addition,the multi-time scale scheduling strategy taking into account IDR can effectively alleviate the power fluctuation caused by the source and load error and reduce the carbon emissions of the system,so as to realize the low carbon,economic and stable operation of IES.
