Abstract :
Stability issue of DC bus in power system with multi-sources such as renewable and distributed energy sources is investigated. A simple design with cascade control for individual Buck converter, Boost converter and ICFFB converter to operate stably under constant power load is presented. Integration of these converters into the DC power system and solution for subsystem dynamic interactions are analyzed and verified by simulation.
