Abstract

The coupling between constant power loads (CPLs) is an important cause of system oscillation in a radial DC microgrid. First this paper deduced the equivalent circuit of a single-source dual-CPL (SSDC) system. Then, by Rouse-Hurwitz stability criterion one of the essential requirments of SSDC system stabilization is obtained, i.e. keep the parameter heterogeneity (PH) between CPLs filters is necessary. The root trajectory of the SSDC system shows that the PH of filter capacitors can improve system stability. Therefore a virtual capacitor control (VCC) of the point-of-load (POL) converter is introduced to produce the PH. The model of SSDC system was built with Matlab/Simulink. The simulation results show that the stability conditions is correct and the VCC can effectively suppress the system oscillation
