| 摘要: |
| 以4端口柔性环网控制装置为例，系统地分析了柔性环网控制装置在10 kV交流配电网中的组网方式和运行控制策略，并进行了系统仿真。在仿真过程中，为了解决复杂电力电子装置在电力系统大时间尺度仿真时速度较慢的问题，采用了一种柔性环网控制装置的简化模型。研究和仿真结果表明，柔性环网控制装置的应用有助于提高配电网的性能，如能够实现交流配电线路的闭环运行、对潮流的优化控制、系统故障时不停电负荷转移、对负荷的就地无功补偿和降低系统备用容量。 |

| Abstract: |
| The connection mode and control strategy of a four-port FLNC(Flexible Looped Network Controller) in a 10 kV AC distribution network is systematically analyzed, and the system is simulated. During the simulation process, a simplified model of FLNC is adopted to improve the large time scale simulation efficiency for the power system connected with complicated power electronic devices. Research and simulative results show that the application of FLNC can effectively enhance the performance of distribution network in aspects of the realization of the closed-loop operation of AC distribution network, optimized power flow, uninterruptible load transfer, reactive power compensation, and decreased system reserve capacity. |
