中文摘要:

      综合能源系统作为能源互联网的基础，是提高能源利用率和可再生能源消纳能力的重要技术。需求响应通过引导用户改变用能的习惯和方式，对于优化负荷的分布和提高系统运行的经济性等方面的作用正逐渐得到了重视。通过对用户需求侧进行综合需求响应的精细化建模，以综合能源系统运行总成本为最低，建立了计及可削减负荷、可平移负荷、可转移负荷及可替代负荷的精细化模型，提出了考虑综合需求响应的综合能源系统日前优化调度。算例结果表明，通过综合需求响应可以优化园区的负荷曲线，提高能源的利用率和系统运行的经济性。

英文摘要:

      As the basis of energy Internet, integrated energy system is an important technology to improve energy utilization and renewable energy consumption. By guiding users to change their habits and ways of energy consumption, demand response has been paid more and more attention to optimize the load distribution and improve the economy of system operation. Based on the refined modeling of the comprehensive demand response on the user demand side, a refined model considering the reducible load, translatable load, transferable load and replaceable load is established with the total operation cost of the integrated energy system as the lowest. The day-ahead optimal scheduling of the integrated energy system considering the comprehensive demand response is proposed. The case study shows that the comprehensive demand response can optimize the load curve of the park and improve the energy utilization and the economy of the system operation.
