Abstract

Maintaining the stability of DC bus voltage is the premise of safe and efficient operation of DC energy conversion system. Aiming at the problem that the interaction between AC/DC interconnecting converter and constant power load will reduce the voltage quality of DC bus and cause system oscillation, this paper establishes an impedance model between DC port and constant power of AC/DC interconnecting converter, and studies and analyzes the influence of DC voltage sag control and load power on the stability of DC system. A DC voltage inertial support control method is proposed, which can increase the capacitive component of DC port impedance of AC/DC converter, enhance the inertia and stability of DC system, and improve the ability of bus voltage to resist load fluctuation.
