“…For operation of the system under optimum wind power capture, the electrolyser harnessed a fraction of the generated power, while the rest was injected to the grid. For operation at the rated power of the electrolyser, it was necessary to be connected to the grid because the energy production from wind was lower during most of the under investigation time [38].…”

“…The power contribution of the wind turbine can be modelled as a voltage‐dependent current source

i_{normalR}

that is function also of the rotational speed

Ω

and, indirectly, of wind speed

ν

, according to the following expression

i_{normalR} = \frac{1}{L_{G}} ()(, \sqrt{3} Φ - \frac{π u_{normalE}}{3 p Ω}),

where

L_{G}

Φ

and

p

are, respectively, the synchronous inductance, the concatenated magnetic flux and the number of magnetic pole pairs of the permanent‐magnet generator [15].…”

“…The electrolyser can also be modelled as a current source

i_{normalE}

with non‐linear output resistance. The current–voltage characteristic is appropriately described by the function

u_{normalE} = h ()(, i_{E}) = n (][, U_{rev} + \frac{r_{e}}{A} i_{normalE} + s_{normale} \ln ()(, \frac{t_{e}}{A} i_{normalE} + 1)),

where

n

is the number of electrolytic cells in series,

U_{rev}

is the reversible cell voltage,

A

is the electrode area and {

r_{normale}

s_{normale}

t_{normale}

} are empirical coefficients that depend on the electrolyte temperature [15].…”

“…A cascade control structure is considered here for this task. Its main objective is to reject the disturbance introduced by the renewable resource that can be modelled as a non‐linear function of wind speed

ν

as was described in a previous work [15]. The cascade control comprises an outer controller that computes the reference for the inner controller, being common practice to design the inner loop much faster than the outer one to avoid undesirable interactions and instability.…”
