This paper presents modeling and control analysis of a combined Wind-H2 system connected to an electrical grid and supplying a local electric load. The system consists of a wind farm for electricity generation and an electrolyzer to produce hydrogen for a filling station. A computer program has been developed in MATLAB for simulating the operation and control of the integrated system. Energy balances and hydrogen flow balances are calculated for each time step based on a system model and the specified control strategy. The input of this program are hourly wind speed, characteristics of wind turbine generators, hourly load demand, maximum grid capacity, rated power of electrolyzer, and minimum operating power of electrolyzer. The hydrogen produced will be supplied to a filling station where local vehicles can be filled. Hydrogen production is evaluated and the number of cars served per year is estimated.
