• Integrated Renewable Microgrid: The system combines multiple energy sources and components—PV emulator, wind turbine emulator, battery bank, AEM electrolyzer, and fuel cell—into a cohesive microgrid, enabling hands-on understanding of energy flow and hydrogen-based electricity generation.
• PV and Wind Emulators for Controlled Testing: PV Emulator: A programmable solar panel emulator replicates I-V characteristics under varied conditions such as irradiance and temperature. It allows real-time scenario simulation using LabVIEW-based software.
• Wind Turbine Emulator: Simulates turbine behavior using mathematical models and a motor-generator setup to mimic real wind profiles and mechanical responses.
• Hydrogen Production with AEM Electrolyzer: An Anion Exchange Membrane (AEM) electrolyzer generates green hydrogen using distilled water and renewable electricity. It is strategically integrated at the microgrid’s Point of Common Coupling (PCC) to enable real-time balancing of renewable energy with hydrogen production.
• Fuel Cell-Based Electricity Generation: Stored hydrogen is supplied to a proton exchange membrane fuel cell (PEMFC), converting chemical energy into electrical energy. The output powers residential loads through a charge controller, battery bank, and inverter setup.
• Battery Storage and System Balancing: The lithium-ion battery bank stores excess energy, stabilizes microgrid operation, and acts as a buffer for load management and peak shaving.
• Real-Time Monitoring and Control: The system features LabVIEW software for monitoring parameters like voltage, current, power, hydrogen production rate, and fuel cell efficiency, enabling users to adjust inputs and observe system dynamics instantly.
• Robust Safety and Automation Features: Includes hydrogen drying units, pressure regulators, auto shut-off valves, and leak detectors, ensuring safe operation across all subsystems.

• The Green Hydrogen Microgrid is a laboratory-scale integrated energy system designed for hands-on education and advanced research in hydrogen-based microgrids.
• Renewable sources such as solar PV, wind emulators, or programmable DC supplies feed power into a common DC microgrid bus.
• An open-architecture microgrid controller manages energy flow between sources, loads, hydrogen subsystems, and storage elements.
• Surplus renewable power is routed to an electrolyzer, where deionized water is converted into green hydrogen through electrolysis.
• The generated hydrogen is stored in certified vessels with pressure regulation, safety valves, and hydrogen leak detection.
• During energy deficits, stored hydrogen is supplied to a PEM fuel cell to generate electrical power.
• The system provides open-source software access, allowing users to modify control logic, energy management algorithms, and dispatch strategies.
• Direct access to DC–DC converters, DC–AC inverters, and protection hardware enables real-time control, algorithm testing, and hardware-in-the-loop experimentation.
• A comprehensive data acquisition system supports performance analysis, efficiency studies, and microgrid optimization research.
