U.S. Wind to Hydrogen Modeling, Analysis, Testing, and Collaboration
Approach: Simulation
models and data
preparation
TurbSim & OpenFAST to
create power profiles
Generate AC output profiles
Estimate DC output with a
rectifier efficiency
Data Flows
Wind speed (mean) = {4, 6, 8, 10, 12, 14, 16, 20} m/s

RSCAD model sends current
setpoints to the electrolyzer
system
Up to 50 us (target: 40 ms)
Synchronized sensor
measurements and storage
Open-loop simulation
OpenFAST and RSCAD are
decoupled: 1) prepare offline
data and 2) feed it into the
RSCAD model
