| 摘要: |
| 随着分布式电源接入配电网的装机容量增加，配电网公共耦合点功率不确定和节点电压越限成为亟待解决的问题。为提高有源配电网运行的效率和可靠性，提出了基于外部一致性协议的分布式电源协同控制策略。通过不同控制目标将分布式电源分为电压控制组和功率控制组；设计了一致性控制律对有源配电网节点电压以及公共耦合点的功率进行调节和协调控制；采用极限理论证明了配电网分布式电源控制系统的收敛性和稳定性。在IEEE 33节点标称模型中，验证了所提策略具有更快的收敛性和鲁棒性，并在含有多个台区的实际中低压配电网模型中验证了策略的有效性。 |

| Abstract: |
| With the increasing installed capacity of distributed generation connected to distribution network, the power uncertainty of the point of common coupling for distribution network and the limit exceeding of the node voltage have become urgent problems to be solved. In order to improve the efficiency and reliabi-lity of active distribution network, a distributed generation cooperative control strategy based on external consistency protocol is proposed. The distributed generation is divided into voltage control group and power control group by different control objectives. A consistent control law is designed to regulate and coordinate the node voltage of active distribution network and the power of point of common coupling. The theory of limit is adapted to prove the convergence and stability of the distributed power control system for the distribution network. In IEEE 33-bus nominal model, the faster convergence and robustness of the proposed strategy are verified, and the effectiveness of the proposed strategy is verified in the actual medium and low voltage distribution network model with multiple stations. |
