Design, Operation, and Control of Remote Microgrids - Integrating Standards and Advanced Simulations for Sustainable Energy Solutions: A Case in Vietnam

The design, operation, and control of remote microgrids are essential for providing reliable and sustainable power in off-grid or isolated areas. This paper presents a comprehensive study on remote microgrid systems, focusing on key components such as generation and storage technologies, load management, substations, and microgrid controllers to ensure stable and efficient operations. The study emphasizes the role of Battery Energy Storage Systems and diesel generators in maintaining grid stability, particularly during emergencies and varying load conditions. To assess system performance, a detailed simulation model was developed using the MATLAB/Simulink platform. This model incorporates essential elements such as the microgrid controller, operator control room, and system-level monitoring. The simulations evaluate system behaviour under various scenarios, including feeder switch operations, the Battery Energy Storage Systems load pickup after generator failure, and islanding during low-load conditions. These simulations were designed to test the microgrid's ability to autonomously manage energy, enhance resilience, and maintain operational stability under different operating conditions. The results demonstrate the effectiveness of advanced microgrid control strategies in optimizing energy management, minimizing disruptions, and ensuring reliable operation in remote areas. This study provides valuable insights into the development and deployment of remote microgrids, offering a strong foundation for sustainable energy solutions in underserved regions. The planning and design align with industry standards, which are detailed in the relevant section of this paper.
