Hierarchical Structure of Microgrids Control System

TLDR

Advanced control strategies are essential for realizing microgrids. The paper reviews current hierarchical control strategies for microgrids and outlines future trends. The hierarchical control structure comprises primary, secondary, and tertiary levels that manage microgrid performance and economics, with comparative analysis of control approaches and discussion of inter‑hierarchy coordination.

Abstract

Advanced control strategies are vital components for realization of microgrids. This paper reviews the status of hierarchical control strategies applied to microgrids and discusses the future trends. This hierarchical control structure consists of primary, secondary, and tertiary levels, and is a versatile tool in managing stationary and dynamic performance of microgrids while incorporating economical aspects. Various control approaches are compared and their respective advantages are highlighted. In addition, the coordination among different control hierarchies is discussed.
