Abstract

This paper discusses the dynamic interaction of multi-paralleled inverters within a weak grid. Interactive current and common current models are proposed to explain the interaction among these inverters, which are studied with both open loop and closed loop analysis. An aggregated model is proposed to describe the totality of multi-inverters. Additionally, system stability is explicitly studied and classified as interactively and commonly stable. The study is validated by simulations and experiments.
