Abstract:

Constant Power Loads (CPL) are considered as the most destabilizing loads in DC microgrids because of their negative incremental impedance. Almost tightly regulated converters are considered as CPLs, which makes it very important issue to handle their connection and disconnection to the DC bus of the microgrid in order to have soft current transients. This paper presents a study of the impact of CPLs connection and disconnection into the DC microgrid when the DC source converter is controlled. Two controllers are implemented for this purpose: the first is a linear controller using PI regulators; the second is a nonlinear one, using flatness control and sliding mode control. Simulations and experimental results are provided to show the correctness and validity of the study.
