摘要：
The complex impedance characteristic of DC network in AC/DC hybrid distribution system is easily to induce high-frequency oscillation. This paper reveals the influence of the DC line on the stability and upper limit of transmission power of the system by researching the relationship between the DC distribution line and the dominant eigenvalues of the system. A distributed active damping strategy is proposed, and the sensitivity of the active damping controller to the oscillation under different access positions is analyzed. Finally, time domain simulation verifies the correctness of the theory and the effectiveness of the proposed control strategy.
