| 摘要: |
| 对比现有电网分区运行模式与新型柔性互联运行模式，并阐述柔性直流分区互联装置的基本工作模式；介绍分区互联装置的基本结构，并研究装置在分区间有功支援与动态无功支撑过程中的工作原理；考虑电网N-1静态安全性与暂态电压稳定性，提出分区柔性互联城市电网最大供电能力的定义与模型，并给出一种简化的逼近求解算法。某电网示范工程实际算例验证了所提方法的正确性；与传统分区运行相比，柔性互联后最大供电能力得到提升。 |

| Abstract: |
| The novel flexibly-interconnected operating modes of power grid is compared with the present partitioned operating mode and the basic working modes of flexible DC inter-partition connecting device are analyzed. The basic structure of inter-partition connecting device is introduced and its working principles during the active-power support and the dynamic reactive-power support among partitions are investigated. With the consideration of N-1 static security and transient voltage stability of power grid, the definition and model of total power-supply capability of urban power grid with flexibly-interconnected partitions are proposed and a simplified approximation method is given to solve it. Case study for a pilot project verifies the correctness of the proposed method. Compared with the traditional partitioned operation, the total power-supply capability of flexibly-interconnected partitions is enhanced. |
