Abstract

In the microgrid applications, the converters come in all sizes and from different manufacturers, thus their closed-loop dynamics and AC side output filters are not going to be the same. The dispersed locations of these converters also lead to unequal power line impedances seen from the converters. These system parameters asymmetry affects the autonomous load sharing operations both in the steady state and in the transient. This paper discusses the impacts of these parameters asymmetry on the dynamics of the entire system. Based on the dynamic model analysis, this paper also provides some existing methods to address these problems.
