Advanced Control Architectures for Intelligent Microgrids—Part I: Decentralized and Hierarchical Control

TLDR

The paper reviews advanced control techniques for microgrids. It surveys decentralized, distributed, and hierarchical control strategies for grid‑connected and islanded microgrids, including recent stability analyses and mains‑grid‑mimicking hierarchical designs.

Abstract

This paper presents a review of advanced control techniques for microgrids. The paper covers decentralized, distributed, and hierarchical control of grid connected and islanded microgrids. At first, decentralized control techniques for microgrids are reviewed. Then, the recent developments in the stability analysis of decentralized controlled microgrids are discussed. Finally, hierarchical control for microgrids that mimic the behavior of the mains grid is reviewed.
