Abstract

Microgrids provide a viable way to integrate renewable energy sources, enhance energy security, and boost grid resilience. However, substantial operational and technological challenges exist in achieving smooth synchronization with the larger power grid. The primary challenges associated with microgrids, and grid synchronization are examined extensively in this paper. These difficulties include phase and frequency coordination, problems with power quality, methods for islanding and reconnecting, infrastructure for communication and control, and regulatory barriers. The research examines new developments in smart grid technology, sophisticated control algorithms, and creative finance strategies that may enable more seamless synchronization and help microgrids reach their full potential. The research also proposes a method for managing energy while emphasizing the importance of implementing an effective energy management plan, particularly in energy storage systems. A method is suggested for managing energy storage and controlling energy storage system charge and discharge in a microgrid connected to a solar system, using linear programming optimization methods to minimize variable electricity prices and compare it with heuristic optimization approaches. In order to overcome the remaining obstacles and clear the path for the broad deployment of microgrids, the article ends with suggestions for future research and development projects.

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
