Abstract: There are difficulties in analyzing the stability of microgrids since they are located on various network structures. However, considering that the network often consists of passive elements, the passivity theory is applied in this paper to solve the above-mentioned problem. It has been formerly shown that when the network is weakly strictly positive real (WSPR), the DC microgrid is s...

Direct current microgrids (MGs) are an emergent option to satisfy new demands for power quality and integration of renewable resources in electrical distribution systems. This work addresses the large-signal stability analysis of a DC-DC bidirectional converter (DBC) connected to a storage device in an islanding direct current (DC) MG. This converter is responsible for controlling the balance o...

DC microgrids initiated the change of a paradigm regarding concept about electrical distribution networks, especially in context distributed generation associated with renewable energies. However, this new reality opens area research, which several aspects must be carefully studied. Indeed, bipolar design is one principal dc microgrid configurations considering its characteristic wiring. Althou...

Distributed generation takes center stage in today's rapidly changing energy landscape. Particularly, locally matching demand and generation in the form of microgrids is becoming a promising alternative to the central distribution paradigm. Infrastructure networks have long been a major focus of complex networks research with their spatial considerations. We present a systemic study of solar-po...

The increasing demand for energy and the high penetration of distributed resources require evolution current electrical systems toward smarter more reliable electric grids. In this regard, microgrids (MG) play a vital role in integrating (DER), loads, storage systems. However, microgrid architectures lack versatility flexibility terms control, limiting their expansion. This paper presents multi...

Microgrids are small-scale power networks that include renewable energy sources, load, storage systems, and management systems (EMS). Lithium-ion batteries the most used battery for in microgrids due to their advantages over other types of batteries. However, protect from explosion manage charge discharge based on state-of-charge (SoC) value, this type requires use an system. The main objective...

Direct-current (DC) microgrids have gained worldwide attention in recent decades due to their high system efficiency and simple control. In a self-sufficient energy system, voltage control is an important key dealing with upcoming challenges of renewable integration into DC microgrids, thus storage systems (ESSs) are often employed suppress the power fluctuation ensure stability. this paper, pe...

The continued commissioning of DC microgrids in an effort to achieve net-zero carbon levels the atmosphere demands large-scale deployment converters make power from renewable energy sources, such as solar PV, usable. To control these inherently non-linear using classical linear methods, averaged modelling techniques are employed. These methods laborious and easily become intractable when applie...

This article proposes an adaptive coordinated control strategy for the networked AC/DC microgrids (MGs) to enhance frequency and dc voltage stability of system while keeping proper power sharing. First, a based on synchronverter virtual machine (VDCM) converters connecting AC DC MGs is proposed, which consisted governor inertia regulator besides sharing controller. Following, in order performan...
