“…The review and classification of topologies of the hybrid AC/DC microgrids has been discussed with a focus on the interconnection of the different networks and the conventional grid [27], while an overview of the AC and DC microgrid technologies has also been presented detailing the elements and issues involved in the implementation and development, viz. protections, power converters, economic analysis, and availability [28].…”

“…Some of the papers have presented the overview of microgrid systems [8,[13][14][15]20,[22][23][24]27,28,33,34] focusing on the various technologies and recent developments and their potential application for rural electrification and islanded purposes; a review of renewable energy resources for microgrid application was also presented [19]. Some other papers have focused on the review of control strategies of microgrid and autonomous applications with the aim of achieving proper and effective coordination of a cluster of microgrids in electrical systems for optimal operation [6,7,9,11,12,17,21,25,26].…”

Abstract:There is a growing interest in the application of microgrids around the world because of their potential for achieving a flexible, reliable, efficient and smart electrical grid system and supplying energy to off-grid communities, including their economic benefits. Several research studies have examined the application issues of microgrids. However, a lack of in-depth considerations for the enabling planning conditions has been identified as a major reason why microgrids fail in several off-grid communities. This development requires research efforts that consider better strategies and framework for sustainable microgrids in remote communities. This paper first presents a comprehensive review of microgrid technologies and their applications. It then proposes the STEEP model to examine critically the failure factors based on the social, technical, economic, environmental and policy (STEEP) perspectives. The model details the key dimensions and actions necessary for addressing the challenge of microgrid failure in remote communities. The study uses remote communities within Nigeria, West Africa, as case studies and demonstrates the need for the STEEP approach for better understanding of microgrid planning and development. Better insights into microgrid systems are expected to address the drawbacks and improve the situation that can lead to widespread and sustainable applications in off-grid communities around the world in the future. The paper introduces the sustainable planning framework (SPF) based on the STEEP model, which can form a general basis for planning microgrids in any remote location.

“…The power electronic interface of winds turbines, fuel cells, and PV modules with an existing AC microgrid is discussed in [5]. In [6], a comparative analysis on the component integration with AC and DC microgrids is performed. It is recognized that these components are inherently DC, or require an intermediate AC-DC-AC conversion stage.…”

“…To effectively deal with the output fluctuation of these renewable sources, this study also used batteries to form a dc distribution power system. Such a dc distribution power system was considered because renewable and alternative power sources could be connected to the integrated dc power network in a simpler manner than ac systems [23]. This section describes the modeling methodology that has been used in this study for the power output of wind generator and PV modules.…”

Abstract:The need for reduction in power consumption for public facilities has increased after the occurrences of multiple blackout events. In an effort to enable the development of green and smart social infrastructure, this paper introduces a design for a sustainable and efficient transportation system (SETS). For this design, renewable power sources and efficient electric drives are considered to be crucial technologies. Considering the subway station as an illustrative example, a power system design that uses wind and solar energy as major power sources is studied. The adjustable speed electric drive system that uses synchronous reluctance machines for ventilation systems contributes to increasing the overall power consumption efficiency. The effectiveness of the proposed SETS system is verified through a set of various field measurement data and simulation results. While the verification results demonstrate that operation of SETS is enabled by effective integration of renewable sources and efficient ventilation systems, future research directions have also been identified.
