This paper analyzes the operation of a grid-assisted wind power system dedicated to hydrogen production. Several operation modes are evaluated with the aim of establishing control strategies for different requirements such as optimum wind power capture, maximum H2 production rate and maximum clean H2 production. Each operation mode is achieved by specific control of the grid-side power electronic converter. The operation of the wind turbine, the electrolyzer and the electronic converter connected to a common DC-bus are represented on the same voltage–current plane. Basic schemes of controllers are suggested to fulfill operation requirements. Curves of power and H2 production rate as function of wind speed are displayed for each mode. Also, conclusions about contribution of wind energy to clean H2 are drawn.
