| English 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. |
