TL;DR: Several ideas for modeling, analysis, and system-level design of such systems, including power flow control, protection, stability, and subsystem interactions, are presented, especially in the presence of renewable energy sources.

TL;DR: A state-feedback quasi-static SRF-PLL model is proposed, which can identify and quantify the inherent frequency self-synchronization mechanism in the converter control system and explain the PLL instability issues and the related islanding-detection methods in early publications and industry reports.

TL;DR: In this article, an impedance-based analysis method was proposed to analyze the grid-synchronization stability issue in paralleled three-phase converter systems, which showed that the multivariable generalized inverse Nyquist stability criterion (GINC) can be used to predict the system stability based on the grid and inverter impedances in the synchronous d-q frame.

TL;DR: In this article, a two-stage topology using a full bridge in series with a bidirectional synchronous rectifier dc-dc converter as a single-phase ECC for dc nanogrid was investigated.

TL;DR: In this paper, a hierarchical dynamic decoupling of generation, distribution, and consumption by using bidirectional electronic power converters as energy control centers is discussed. But, the authors do not consider the potential for the use of new power electronics technologies in electrical energy generation and consumption.
