摘　　要：为了更好地展现园区综合能源系统中多种能源网络耦合互补、协调配合的特点,有效提高系统运行的经济性,提出了在电、热、冷、气4种网络负荷约束下考虑综合需求响应的冷热电联供型园区综合能源系统优化运行模型。首先在某园区建立电、热、冷、气4种能源网络,以及建立系统内部多种能量转换设备和储能装置的数学模型,同时考虑供热/供冷系统具有的热惯性,在此基础上,以综合能源系统建设运行成本与综合考虑价格型、激励型、替代型需求响应补偿成本之和最小为目标函数构建优化调度模型,并采用MATLAB平台中的Gurobi求解器对所提模型进行求解。通过算例分析可以得到:在能更好体现多能耦合互补特点的4种网络构成的园区综合能源系统中,综合考虑价格型、激励型、替代型需求响应的方式起到对负荷进行“削峰填谷”的作用,能更好地缓解系统高峰时期的供能压力,更有效地降低园区综合能源系统的日内运行成本,使得系统运行的总成本降低5.7%,有效提高了系统运行的经济性。In order to show the characteristics of coordination and cooperation of various energy networks better in the park integrated energy system,and effectively improve the economy of the system operation,an optimal operation model of the park integrated energy system based on combined heating and cooling power supply is proposed,which considers the comprehensive demand response under four kinds of network load constraints.Firstly,four kinds of energy networks of electric heating and cooling are established in a park,and mathematical models of various energy conversion equipment and energy storage devices inside the system are established.Meanwhile,the thermal inertia of heating or cooling system is considered.On this basis,the optimal scheduling model is carried out with the optimal economy of the system,and the Gurobi solver in MATLAB platform is used to solve the proposed model.Through the analysis of examples,it can be concluded that the comprehensive demand response mode can plays the role of“peaking and valley filling”on the load,and can alleviate the energy supply pressure better than the mode without considering the comprehensive demand response during the peak period of the system,and can more effectively reduce the daily operating cost of the integrated energy system in the park,the total operating cost of the system is reduced by 5.7%,so that the economy of the system operation is improved.
