A Review: Controlling Techniques of DC Microgrids

DC microgrids have emerged as an efficient power system design approach in academia and industry offering the potential to integrate Distributed Energy Resources DERs even in challenging locations such as offshore platforms and rural villages The intermittent nature of DERs poses integration challenges for conventional power systems In contrast DC microgrids can accommodate these uncontrollable behaviours This paper provides a comprehensive overview of controlling techniques for DC microgrids focusing on centralized decentralized and distributed controlling methods Each controlling approach possesses unique advantages and disadvantages that must be carefully evaluated when selecting an appropriate control strategy This paper aims to provide researchers with a comprehensive understanding of the available controlling methods in terms of the communication architecture in DC microgrids facilitating informed decisionmaking on their respective research procedures
