The supply of electricity to remote regions is a significant challenge owing to the pivotal transition in the global energy landscape.To address this issue

an off-grid microgrid solution integrated with energy storage systems is proposed in this study.Off-grid microgrids are self-sufficient electrical networks that are capable of effectively resolving electricity access problems in remote areas by providing stable and reliable power to local residents.A comprehensive review of the design

control strategies

energy management

and optimization of off-grid microgrids based on domestic and international research is presented in this study.It also explores the critical role of energy storage systems in enhancing microgrid stability and economic efficiency.Additionally

the capacity configurations of energy storage systems within off-grid networks are analyzed.Energy storage systems not only mitigate the intermittency and volatility of renewable energy generation but also supply power support during peak demand periods

thereby improving grid stability and reliability.By comparing different energy storage technologies

such as lithium-ion batteries

pumped hydro storage

and compressed air energy storage

the optimal energy storage capacity configurations tailored to various application scenarios are proposed in this study.Finally

using a typical microgrid as a case study

an empirical analysis of off-grid microgrids and energy storage integration has been conducted.The optimal configuration of energy storage systems is determined

and the impact of wind and solar power integration under various scenarios on grid balance is explored.It has been found that a rational configuration of energy storage systems can significantly enhance the utilization rate of renewable energy

reduce system operating costs

and strengthen grid resilience under extreme conditions.This study provides essential theoretical support and practical guidance for the design and implementation of off-grid microgrids in remote areas.
