| 随着新型电力系统源荷不确定性日益上升,面向短周期应急保供电需求的备用资源规划方案可能在长周期电力系统运行场景下存在冗余,造成了电网规划资源的浪费,因此考虑长短周期的源荷储两阶段备用资源规划方法是兼顾电力系统保供电能力和运行经济性的重要手段。首先,分析引发备用资源规划冗余的关键不确定性因素,包括新能源、负荷与线路故障的不确定性,构建基于机会约束的源荷储两阶段备用规划模型。然后,基于两阶段规划问题的解耦特性,提出了两阶段备用规划模型的单阶段近似求解方法,通过内嵌保供电能力约束,实现了源荷储备用规划模型的高效求解。最后,采用改进的IEEE-30节点测试系统验证所提方法的有效性。算例结果表明,所提源荷储两阶段备用资源规划方法在不显著增加计算时间的情况下,可使系统平均功率缺额降低约54.7%,备用规划成本降低约26.7%,新能源弃电率降低约60.4%。因此,所提方法能够有效提升系统保供电能力,改善新能源消纳效率,促进电力系统安全经济运行。 |

| With the increasing uncertainty of source-load in the new power system, the allocation of reserve resources designed for short-term emergency power supply may be over-configured in long-term power system operation scenarios, resulting in a waste of grid planning resources, so proposing a two-stage reserve resource planning method that considers both long-term and short-term cycles is an important means to balance the supply security and operational economy of the power system. First, the key uncertainty factors that lead to redundant reserve resource planning are analyzed, including the uncertainties of new energy sources, loads, and line failures. A two-stage reserve planning model based on chance constraints for source-load-storage is then constructed. Subsequently, based on the decoupling characteristics of the two-stage planning problem, a single-stage solution method for the two-stage reserve resource planning model is proposed. The power supply guarantee constraint is embodied to further achieve the effective solution of the source-load-storage backup planning model. Finally, the effectiveness of the proposed method is verified in the modified IEEE-30 bus test system. The case study results show that, without significantly increasing the computation time, the proposed two-stage reserve resource planning method for source-load-storage can reduce the average power shortage by about 54.7%, lower the reserve planning cost by about 26.7%, and decrease the new energy curtailment rate by about 60.4%. Therefore, the proposed method can effectively enhance the system's power supply capability, improve the efficiency of new energy consumption, and promote the safe and economic operation of the power system. |
