Key Features

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.
