中文摘要:

      综合能源供应商作为多能源供应主体，可以参与市场化交易。为探索综合能源供应商在电力市场环境下新的盈利点，构建了考虑需求响应的多主体互动机制，并充分考虑光伏出力、多元用能需求、市场电价以及需求响应资源潜力的不确定性，采用区间优化方法构建了表征综合能源供应商日前运行优化问题的混合整数线性规划模型，得到综合能源供应商的购能、设备运行以及需求响应资源调用等策略。算例验证结果表明，需求响应机制可以有效降低购电成本，增加综合能源供应商的运行收益。

英文摘要:

      Integrated energy service provider, as a multi-energy supply entity, can participate in market transactions. To explore new profit sources for integrated energy service provider in the electricity market environment, a multi-agent interactive mechanism considering demand response has been constructed. This mechanism takes into account the uncertainties of photovoltaic output, diverse energy demand power, market electricity price, and demand response resource potential. By employing interval optimization methods, a mixed-integer linear programming model is developed to represent the day-ahead operational optimization problem for integrated energy service provider,yielding strategies for energy procurement, equipment operation, and demand response resource utilization. Case studies are verified that demand response mechanism can effectively reduce purchased cost and increase the operational revenue of integrated energy service provider.
