摘　　要：综合能源园区是推进能源系统低碳发展的关键应用场景。针对电、气、冷、热耦合的综合能源园区,给出一种供需互动的园区综合能源系统日前优化方法。基于离散混合自动机(discrete hybrid automaton,DHA)架构,搭建考虑多种运行模式的综合能源系统设备级模型与系统级模型;通过搭建用户空调负荷预测模型,给出基于调节价格的园区需求侧负荷响应机制;通过搭建供需互动的园区综合能源系统双层优化模型,计算在低成本模式与低碳模式下的园区综合能源系统日前优化结果。算例仿真验证了所提建模方法在描述设备运行模式的优势,计算园区供需互动带来的经济效益,并评估园区在低碳运行模式下的减排能力。最后,讨论通过清洁机组与储能设备的升级改造实现零碳园区的可行性,以及在设计规划阶段需要考虑的评估指标。Parks with multiple energy systems have become a key application scenario in achieving carbon neutralization. This paper proposes a day-ahead optimization model of the multiple energy system, which has electricity, natural gas, cooling and heat integrated. Based on the discrete hybrid automaton, this paper proposes equipment level and system level modeling methods of the park multiple energy system, which considers the complexed operation mode. This paper also proposes a regulated price-based demand-side response mechanism through an air conditioning load forecasting model. And a bi-level optimization model of the park multiple energy system with the interaction of supply and demand is given. A typical park case with multiple energy system is used to verify advantages of the modeling method, calculate the economic benefits brought by the demand-side response, and evaluate the maximum carbon emission reduction capacity of the park. Finally, the impact of the upgrading of renewable energy unit and energy storage equipment on the carbon neutralization is discussed.
