The development of the energy internet promotes the efficiency, economy and security of the energy system. In the Integrated Electrical and Natural Gas Network (IEGN), linepack reserves not only secure the safe operation of the natural gas network, but also could be employed by gas turbines to provide fast-response flexibility. It plays an increasingly significant role in balancing the electrical network with renewable energy sources and multi-energy utilizations. Besides, the linepack reserve also guards the coordination between networks, and the normal function of multi-energy utilizations, including combined cooling, heat and power, aka trigeneration plants. To promote the safety and coordination of the IEGN, this paper novelly integrates the linepack reserve into the dispatch process and proposes a multi-objective optimal dispatch model for the IEGN with trigeneration plants to simultaneously promote its economy, safety and efficiency. NSGAII is employed to solve it. Finally, case studies demonstrate its effectiveness.%能源互联网的发展提高了系统的能效、经济性和安全性.储气备用不仅维护了气网自身的安全运行, 还能支持燃气轮机出力快速变化, 提供电网额外的灵活备用, 这对平衡电网中的可再生能源和多能源负荷具有重要意义.此外, 气电网络间的高效协调互补, 与包括冷、热、电三联产设施在内的多能源应用的运行也有赖于充足的储气备用.为促进气电互联网络安全高效地运行, 创新地将储气备用纳入调度优化, 提出了一种含有三联产设施的气电互联网络的多目标最优调度模型, 并使用NSGAII进行求解.算例分析显示了所提方法的有效性.
