Control systems of distributed generation modules aggregated by cascaded boost converters.

Abstract

DC/DC boost converters are usually used to interface the DC output of modern distributed generation resources with the AC system. Distributed generation modules are aggregated to yield the necessary power using either parallel or cascaded architecture. Detailed modeling of an interconnection system incorporating cascaded architecture has not been considered in previous researches. In this paper, suitable control systems for cascaded architecture of power electronic converters in an interconnection system have been studied and modeled in detail. Simulation results indicate the effectiveness of the proposed control systems.
