Smart grids and microgrids that are connected together are all forms of distributed energy systems that may be controlled by a single central system or by a network of distributed systems.

Abstract

There are a number of technical flaws in the current AC-DC microgrid power management systems. Controlling the voltages of linked microgrids depending on their loading circumstances is a key focus of certain control systems while others are more concerned with regulating the currents of interconnected microgrids. On the other hand, current systems are unable to achieve these objectives. To tackle these issues, an autonomous power management strategy is proposed that evaluates the DC microgrid's individual loading condition before importing power from the associated AC microgrid. DC microgrid voltage may be controlled using this method while using fewer converters. The suggested system is completely self-contained while yet allowing generators and tie-converters to be easily installed and removed. Several operational situations have shown the effectiveness of the proposed control method. The results reveal that the proposed approach is capable of efficiently and autonomously regulating the DC microgrid's power shortfall while maintaining increased voltage resilience.
