| 摘要: |
| 提出一种含分布式电源的配电网潮流可行解调节方法。在配电网进行无功控制分区的基础上，定义了配电网分区负载率，然后设计考虑电压自动控制系统AVC站配协调控制的无功平衡优化调节方法。具体包含:配电网无功补偿分区平衡优化调节方法和变电站AVC站配协调调节方法，并且在调节过程中前者优先于后者。对于前者模型采用免疫遗传算法进行求解，对于后者采用直接法进行计算。所提方法通过对配变低压侧无功补偿柜、分布式电源进行无功补偿分区平衡和变电站AVC的电压协调控制，调节出无功分区平衡、各个节点电压满足合格要求、有功网损较低的潮流可行解。成都某实际10 kV 55节点配电网的仿真结果验证了该方法的有效性。 |

| Abstract: |
| This paper proposes a feasible power flow adjusting method for distribution network with distributed power sources. Based on the reactive power partitioned-balance areas of distribution network, load rate of partitioned areas is defined, and then an optimal adjusting method of reactive power balance considering substation coordination of automatic voltage system (AVC) is designed. This method includes an optimal adjusting method for the balance of partitioned reactive power compensation for distribution system and a substation AVC coordinated adjusting method. In the process, the first method is prior to the following method. For the former model, the immunity genetic algorithm (IGA) is employed, and for the other model, the direct solving method is used. The proposed method in this paper could obtain a feasible power flow solution with reactive power partitioned-balance, bus voltage magnitudes satisfying security constraints, and the lower real power loss, by means of using the adjusting strategy on reactive power compensation cabinets of distribution transformer on low voltage side and distributed power sources for both the balance of partitioned reactive power compensation for distribution system and coordinated control with substation’s AVC. Finally, a 10 kV 55-bus real system of Chengdu is simulated, verifying that the proposed method is effective. This work is supported by National Natural Science Foundation of China (No. 51577018). |
