Research on voltage control method of flexible DC distribution network based on improved droop curve
Aiming at the problem of large DC voltage fluctuation caused by excessive active power fluctuation in the traditional DC distribution network voltage control method, a novel DC distribution network voltage control method combining variable slope droop curve and translation droop curve is proposed based on the DC distribution network structure. The DC voltage control model of the converter under the novel DC voltage control strategy is established, and the stability of the model is analyzed. The steady-state and transient control effects of the proposed control method are analyzed by simulation, and the superiority of the proposed method is verified. The results show that compared with the traditional control method, the proposed control method can more effectively adjust the system voltage, prevent the voltage from exceeding the rated value and improve the voltage quality of the system. This study provides a certain reference for the development of DC distribution network.
