摘要(Abstract)：

针对区域综合能源系统因负荷变化及分布式光伏接入导致的供需失衡、节点电压/气压越限和分布不合理等问题,兼顾系统运行成本最低和电压、气压偏移度最小的目标,考虑能源互补,建立了计及负荷和光伏不确定性的区域综合能源系统日前多目标优化调度模型,并使用NBI法构造Pareto前沿以描述多目标问题的解集。模型从调度角度提出了通过系统自我调节、光伏有功削减、无功调节和电转气等控制方案,探讨了不同方案对系统电压、气压控制的效果与运行成本的影响,分析了系统间相互作用与能量流动。最后在算例中对上述多种控制方案进行验证。结果表明,采用无功调节配合储气与使用P2G的方案,能够在日前优化调度中兼顾系统运行成本最优的和电压、气压控制水平最佳的目标。
