摘要
The recently proposed small-AC-signal droop based secondary control is very attractive for microgrids to restore the voltage and frequency of overall system and to share the output power between paralleled distributed generations (DGs). However, the previous work has not discussed the system stability of the novel secondary control method. This paper presents a small-signal model for the microgrids regulated by the novel secondary control method. Then the system stability is analyzed by accessing the eigenvalues of the proposed model. Finally, the correctness of theoretical analysis is verified by both simulation and experimental results.
