| 摘要: |
| 为了加强对有源配电网的运行监测和管理，提出了一种分布式电源接入情形下的有源配电网馈线终端单元(FTU)的优化布置算法。首先，结合有源配电网的特征，从状态估计方法的角度分析了有源配电网的可观测性原理。将节点负荷功率作为伪量测值，通过优化FTU布置可以提高网络的可观测性，达到有源配电网完全可观测性要求，并且在优化布置时考虑了FTU分布对有源配电网停电损失的影响。建立了有源配电网的FTU优化布置数学模型，并且采用遗传算法求解所建立的0-1整数规划模型。最后通过33节点和60节点有源配电网仿真算例表明所提优化布置算法可以保证网络的完全可观和供电可靠要求，并且布置方案在网络结构变化时仍然适用。 |

| Abstract: |
| A FTU optimal placement algorithm in the active distribution network is proposed when the distributed generations are accessed to the active distribution network in order to improve the monitoring and management of the active distribution network. Firstly, according to the characteristics of the active distribution network, the principles of the active distribution network’s observability are analyzed from the view of state estimation. The load power is used as the pseudo-measurement and the observability of the active distribution network can be improved by the FTU optimal placement so that the active distribution network can be completely observable. The active distribution network’s power loss influence of the FTUs’ distribution is considered during the optimal placement. A mathematical model of the FTU optimal placement in the active distribution network is established and the genetic algorithm is used to solve the 0-1 integer programming model. At last, the simulation shows that the optimal placement can guarantee the observability and power supply reliability of the network in the 33-bus and 60-bus active distribution network, and the placement is also adapted to the changes of network structure. This work is supported by National Natural Science Foundation of China (No. 51677025). |
