摘　　要：含可再生能源的电—气—热互联多能源系统可实现多能源网络互联与多能源优化利用,有效解决资源匮乏与能源浪费等问题。能量枢纽是多能源耦合的关键,但现有的能量枢纽优化配置问题未考虑系统运行可靠性的影响。因此,重点研究多能源系统中计及可靠性的能量枢纽优化配置问题。首先,针对风机、变压器、热电联产、燃气锅炉、电储能、热储能等设备组成的能量枢纽,建立了一种新型多能源系统容量协同优化配置的混合整数线性规划模型。然后,根据该双层优化模型计及能量枢纽的运行可靠性,引入失负荷期望等可靠性指标作为约束。最后,为了确定配置方案,结合优化策略进行整体规划,同时得到各机组能量分配情况,对算例进行仿真分析。结果表明,提出的模型有利于负荷供应可靠性的提升。The multi-energy system with electricity-gas-heat interconnection with renewable energy can realize multi-energy network interconnection,multi-energy optimization and utilization,which can effectively solve the problem of resource scarcity and energy waste.Energy hub is the key to the coupling of multi-energy system,but the existing energy hub optimization configuration does not consider the impact of system reliability.The optimal allocation of energy hub for reliability in multienergy system has been concerned.Firstly,a new multi-energy system capacity co-optimal configuration is established for the energy hub composed of wind turbines,combined heat and power units,gas boiler,storage devices,heat storage devices and other equipment,and a hybrid integer linear programming model is proposed.The two-layer optimization model takes into account the reliability of the energy hub,and the loss of load expectation and other reliability indicators.Finally,in order to determine the planning program,the overall planning is combined with the optimization strategy and the proposed method is applied in a region simulation analysis.The obtained results show that the proposed method can improve the reliability of load supply.
