Real-time protection of Renewable Energy-Based microgrids for Power quality enhancement. A case study of Rwamagana Solar Power Plant

Abstract

With an emphasis on Rwanda's power system specifically, this study tackles the crucial requirement for efficient real-time protection techniques in the context of microgrids powered by renewable energy. The research utilizes a thorough methodology that includes a review of relevant literature, analysis of case studies, and a comparative assessment of various protective strategies. The main goals are to determine which real-time protection technique is best and to make suggestions for improving Rwanda's grid stability and dependability. Microgrid operators, technical specialists, legislators, and local communities comprise the research population, guaranteeing a comprehensive grasp of protection challenges. Using the Rwamagana solar power plant as a case study, useful insights into protection shortcomings, respondent competencies, and preferences are provided. Based on criteria like selectivity, cybersecurity precautions, response time, dependability, and affordability, the comparison analysis assesses several real-time protection strategies. The results show that a hybrid technique that combines virtual inertia with droop management and smart inverter control works very well and is in line with Rwanda's power system features and sustainability objectives. The importance of the suggested protective strategy in achieving steady grid functioning and customer satisfaction is emphasized in the conclusion. Future studies should focus on performance assessments, economic studies, the creation of cybersecurity protocols, scaling adaption, integration with energy storage, regulatory issues, and human factors analysis. This study adds to the growing body of knowledge on microgrid protection and provides policymakers, energy experts, and researchers with insightful information. The results offer a road map for enhancing real-time protection tactics and promoting a robust, sustainable, and dependable energy future as Rwanda moves closer to integrating renewable energy.
