随着交通电气化的快速发展，城市道路交通网和配电网在信息-物理层面呈现强耦合态势，交通-电力融合能源系统发展受到广泛关注。首先分析了城市交通-电力融合能源系统的相互影响关系和耦合机理，在此基础上梳理了典型交通-电力融合能源系统的优化建模方法，比较了不同模型的特点和适用范围，并从交通-电力融合能源系统设施规划和运行优化两个应用层面对相关关键技术进行了总结。最后，分析了交通-电力融合能源系统发展存在的问题和挑战，并对该领域未来的重点研究方向进行了展望。

提出一种考虑用户用电灵活性的社区能源系统双层优化模型，在上层，能源运营商通过优化售电价格来最大化其利润；在下层，建立了反映电热水器蓄热特性的热动态模型以及反映洗碗机和洗衣机的负荷可转移特点的运行特性模型。用户根据运营商提供的电价灵活控制电负荷的开关状态及运行时段，最大程度地降低其用电成本。然后，通过上下两层迭代求解该双层优化问题。仿真结果表明，能源运营商可以发挥其定价的灵活性，优化售电价格；而用户可以利用其需求响应能力，从而降低用电成本；此外，提出的双层优化方法可以将供需双方的灵活性结合起来，使能源运营商和用户受益均衡。

供电能力反映了电力系统所能承载的最大负荷，即在给定的发电机运行方式下，模拟系统中负荷的增长模式，不断检验系统的安全约束条件，从而确定系统所能供给的最大供电负荷。然而，随着以天然气为一次能源的燃气发电机发电比重的显著提升，传统供电能力评估方法并没有考虑燃气发电机的一次能源供应以及天然气系统的运行约束，显然并不恰当。为此，提出了基于连续多能流的电-气耦合综合能源系统供电能力评估方法。首先，建立了电-气耦合综合能源系统的多能流模型；接着引入负荷增长参数，提出连续多能流方法，通过预测-校正追踪多能流解曲线；最后，将所提方法应用于修改的14节点电力系统和14节点天然气系统，仿真结果验证了所提方法的正确性和有效性。
