中文摘要:为充分挖掘源-荷侧可调度资源，优化综合能源系统（integrated energy system，IES）的经济性能和低碳效益，提出一种考虑源-荷协调响应的综合能源系统优化调度策略。在能源供给侧，利用余热设备和电-氢耦合系统，构建电、热能灵活转换与输出的源侧响应模型；在负荷需求侧，综合考虑多元负荷的中断、时移等响应特性，并结合电动汽车充电站的运行约束，构建负荷侧响应模型；为评估综合能源系统负荷需求的综合满意程度，提出了一种负荷满意度综合评价指标，通过商业求解器对综合能源系统优化模型进行仿真求解。仿真结果表明，所提策略在保障用能质量的同时有效降低了系统运行成本。

Abstract:To fully exploit the schedulable resources on the source-load side and optimize the economic performance and low-carbon benefits of integrated energy systems （IES）， an optimal scheduling strategy for IES considering source-load coordinated response is proposed. On the energy supply side， a source-side response model enabling flexible conversion and output of electric and thermal energy is established by integrating waste heat recovery equipment and an electro-hydrogen coupling system. On the load demand side， a load-side response model is constructed by comprehensively considering the response characteristics （e.g.， curtailment and time-shifting） of multi-type loads and incorporating the operational constraints of electric vehicle charging stations. To evaluate the comprehensive satisfaction level of load demands in IES， a comprehensive load satisfaction evaluation index is developed. The proposed IES optimization model is simulated and solved using the commercial solver. Simulation results demonstrate that the proposed strategy effectively reduces the system operating cost while ensuring the quality of energy supply.
