Stability analysis and nonlinear current-limiting control design for DC micro-grids with CPLs

Stability analysis and nonlinear current-limiting control design for DC micro-grids with CPLs

In this study, a DC micro-grid consisting of multiple paralleled energy resources interfaced by both bidirectional AC/DC and DC/DC boost converters and loaded by a constant power load (CPL) is investigated. By considering the generic dq transformation of the AC/DC converters' dynamics and the a...
