Oscillation collaborative control method for AC/DC hybrid distribution network under distributed dispatching

The current conventional cooperative control method of AC-DC hybrid distribution network oscillation mainly constructs the dispatching model by centralized dispatching, which leads to poor cooperative control performance due to the lack of analysis of oscillation influencing factors. In this regard, a cooperative control strategy of AC-DC hybrid distribution network oscillation based on mixed integer linear programming is proposed. The factors affecting the oscillation effect are analyzed from three aspects: power intensity, operating power and oscillation control parameters of the distribution network. The tide calculation equations of DC distribution network and AC distribution network are constructed respectively, and the cooperative control function is constructed and solved by distributed scheduling method. In the experiments, the performance of the proposed method is verified for the cooperative control. The experimental results show that when the proposed method is used to control the oscillation situation, the power exchanged in the distribution network is significantly reduced, and the cooperative control performance is more desirable.
