Electrical engineer; Executive, Procurement, Beximco Pharmaceuticals

Md. Shahriyar Rahman is an electrical and electronic engineer (B.Sc., Ahsanullah University of Science and Technology) working in procurement at Beximco Pharmaceuticals, after teaching electrical engineering at Daffodil Polytechnic Institute and earlier roles in data analysis and electrical systems design. The research focuses on power systems and renewable energy: green hydrogen as a grid-flexibility resource, physics-informed digital twins for inverter-dominated grids, and reproducible research for smart grids, resilience and renewable integration.

From Laboratory Efficiency to Lifecycle Value: A Reproducible Research Roadmap for Smart Grids, Power-System Resilience, and Renewable Integration

Coordinated storage, converter, communication, and data-driven control of renewable-rich power systems rely on coordinated and integrated components, but performance under controlled conditions will not ensure long-term deployment value. The review is structured and based on journal publications from 2020-2025 to link the performance of the smart grid, resilience of power systems, lifecycle assessment, and reproducibility. It is a synthesis that is based on six stages of validation, five dimensi

Physics-Informed Digital Twins for Inverter-Dominated Renewable Grids: A Critical Review of Stability, Operational Constraints, and Cyber–Climate Resilience

Models of inverter dominated renewable grids must be able to capture the time-varying operating conditions while maintaining a clear representation of fast control interactions, limited energy reserves, and uncertain measurements. Decisions that can be supported by physics-informed digital twins can unlock their engineering value, but also represent a path to integrate electrical models with adaptive learning. This is a critical integrative review that brings together 45 selected publications on

Green Hydrogen as A Grid-Flexibility Resource: Degradation-Constrained Co-Optimization from Electrolyser Physics to Power Markets

While controllable electricity demand is a benefit of green hydrogen production, aggressive price-responsive electrolysis puts equipment under operational stress and makes hydrogen delivery more complicated. This study proposes a degradation-aware co-optimization framework that connects proton-exchange-membrane (PEM) electrolyser efficiency, start-up and ramping, renewable procurement, hydrogen storage, and electricity charges. A reproducible mixed-integer model is used to compare the operation
