Current source inverters offer advantages of voltage boost, short circuit protection, reduced EMI and direct regeneration. While CSI control strategies are less developed than for a VSI, the topologies are functional duals and have much in common in a control sense. In particular, since CSI voltage regulation is the dual of VSI current regulation, current regulation control strategies for a VSI can...
In this paper, thorough analysis is carried out on a microgrid system with a constant power load. Constant power loads make the system to be unstable due to their negative impedance characteristics and this is proved for the microgrid system by deriving the small signal state space model for the system and then observing the location of the system poles. Subsequently, a sensitivity analysis is carried...
