Microgrids with large‐scale photovoltaic systems constitute a large part of distributed renewable generation in many grids around the world. Managing the performance of such microgrids and especially their interaction with the main power grid is a challenging task, because it requires the control of renewable resources. This paper presents a comprehensive overview of DC‐DC converter structures used in microgrids and presents a new classification for converters. This paper also provides an overview of the control techniques of DC‐DC converters in DC microgrids and the advantages and disadvantages of the control methods are discussed. In connection with the increasing penetration of distributed generation sources (DGS) and renewable sources in power systems and their power management has been raised as a major concern and methods for power management have been investigated in this paper. Finally, a DC microgrid system, which includes a solar system, wind turbine, and battery, is simulated in MATLAB/Simulink software and its performance is analyzed.

“…Dynamic changes from DERs in the network are not considered which can alter the protection settings on which the model is trained. [114,115] Dynamic models for power grid and protection systems that can simulate different cascading failure mechanisms compared to existing quasi-steady state (QSS) models are presented.…”

“…This is because no single mechanism can capture all the aspects of cascading failure resulting in blackouts. The secondary voltage control system has a selective harmonic compensator to reduce harmonics brought on by voltage distortion in [113,114]. Another case is islanded operation caused by voltage harmonics from the DGRs.…”

Microgrid technology offers a new practical approach to harnessing the benefits of distributed energy resources in grid-connected and island environments. There are several significant advantages associated with this technology, including cost-effectiveness, reliability, safety, and improved energy efficiency. However, the adoption of renewable energy generation and electric vehicles in modern microgrids has led to issues related to stability, energy management, and protection. This paper aims to discuss and analyze the latest techniques developed to address these issues, with an emphasis on microgrid stability and energy management schemes based on both traditional and distinct approaches. A comprehensive analysis of various schemes, potential issues, and challenges is conducted, along with an identification of research gaps and suggestions for future microgrid development. This paper provides an overview of the current state of the field and proposes potential areas of future research.

“…Likewise, desperately not only do the central processor and telecommunication schemes retard the fault detection time but the consigning proper signal to the relay. Droop control is a common structure for DCMG protection with no digital communication links employing decentralized commensurate voltage control of segregate converters [18][19][20][21][22]. Nevertheless, this method has some issues • Depending on a central processor, which reduce the reliability • Costly, due to communication link like an aberration of load affiliate voltage, permanent state inaccuracy in voltage amplitude; the current contribution will be decadence due to dissemination of permanent state inaccuracy along resistive connection tie lines.…”

DC microgrids (DCMGs) have significant advantages, but their protection can be a challenge for DCMGs expansion expressly in distributed generation sources’ (DGS) tendance. This paper proposes a quick, and precise strategy to perceive and trip any fault in DCMGs in the free tendance of DGS. A bi‐level multi‐agent system (MAS) is proposed to protect the DCMG and DGs. The MAS first level perceives the fault in DCMG via a discrete wavelet transform (DWT). The multiply of two harvest levels’ summation of DWT is exerted to detect and distinguish DC lines faults. The MAS second level detects the fault in DGS and their switchers to the point of common connection (PCC) via a differential pole (DP) controller. A four bus DCMG containing solar PV and wind sources is implemented, and the results demonstrate that the proposed plan can recognize and trip the fault by 100% of reliability.
