An Analysis of the Obstacles Faced by Microgrids and their Potential

Abstract

Because of the worldwide energy problem, worries about fuel depletion, power outages, and global warming are growing more and more serious. Distributed generators from renewable sources like solar and wind may help solve these issues. Microgrids are a hotbed of study because they serve as a vital link between scattered renewable energy providers and the rest of the grid. The integration of microgrid technology at the load level has been the focus of recent study in the area of microgrids. Traditional power grids are obsolete because of the difficulty of protecting and controlling several linked dispersed generators. Alternatives to the traditional grid, such as a microgrid, are viable because they offer a small platform for the integration of micro resources distributed generators and storage devices at the end users. It is possible to design a microgrid to work either in grid-connected or stand-alone mode depending on the generation, integration potential, and the needs of the consumers. An entirely new power framework is being created by integrating distributed energy resources-based microgrids with traditional power systems. However, the grid's management, protection, operational stability, and dependability are key challenges. However, microgrids have not yet been put into practice in real time or commercialized. An in-depth assessment of the different issues related to microgrids in terms of both technical and economic factors and problems is presented in this review paper.
