“…Single-bus topology can be considered as the simplest microgrid structure. The system will have only one common bus, and all components such as sources, loads, storage devices, are connected to the bus using various converters [62]. Direct connection of storage devices is also possible.…”

DC microgrids are gaining more attention with the increased penetration of various DC sources such as solar photovoltaic systems, fuel cells, batteries, etc., and DC loads. Due to the rapid integration of these components into the existing power system, the importance of DC microgrids has reached a salient point. Compared with conventional AC systems, DC systems are free from synchronization issues, reactive power control, frequency control, etc., and are more reliable and efficient. However, many challenges need to be addressed for utilizing DC power to its full potential. The absence of natural current zero is a significant issue in protecting DC systems. In addition, the stability of the DC microgrid, which relies on inertia, needs to be considered during system design. Moreover, power quality and communication issues are also significant challenges in DC microgrids. This paper presents a review of various value streams of DC microgrids including architectures, protection schemes, power quality, inertia, communication, and economic operation. In addition, comparisons between different microgrid configurations, the state-of-the-art projects of DC microgrid, and future trends are also set forth for further studies.

“…The designed system is simulated in Simulink and the output waveforms are analyzed. The system proves to improve regulation of DC link voltage, reliable supply to the loads and will be an attractive alternative of power in future for small community, school, hospital, and other sectors [6], [7]. The proposed model of the microgrid consists of solar PV, hybrid energy storage system (consisting of battery and supercapacitor), constant and dynamic loads, as shown in Figure 1.…”

The integration of renewable energy resources to utility grid calls for selection of suitable storage system to store generated energy with reliable supply of demand and selection of efficient control system for smooth control of the grid. Battery is the most common energy storage system. Combining a supercapacitor to it makes the system performance better during transients. This paper proposes a hybrid energy storage system with a battery and a supercapacitor to reduce transient power fluctuations and improve the life span of the battery by reducing the charging/discharging cycles with the incorporation of supercapacitor. The battery compensates constant power fluctuations whereas the supercapacitor compensates the transient power fluctuations. This system design offers improved performance, with better regulation of dc link voltage, frequency regulation compared to microgrid with single energy storage. The dynamic performance of the system under varying load conditions has been improved. The work proposes the power management algorithm, which helps in efficient monitoring and smooth control of the entire system. Integration of supercapacitor to the storage system enhances the performance of the microgrid, increases life span of battery and reduces the stress on battery. The DC link bus voltage is efficiently regulated and the demand is supplied reliably.
