As a result, the variation and a closer observation of
grid current is presented in Fig. 12a and Fig. 12b respectively
and corresponding grid output power by Fig. 12c. In order to
cope with the higher power demand with increasing wind
speed, an increase in current is required as the voltage of the
grid remain constant and is found from the simulation result
for the current. Furthermore, it is observable the current
maintain the proper sinusoidal profile as expected from the
PWM inverter. The objective to transfer maximum power to
the grid is no longer questionable as the power corresponds
well with the maximum power with respective wind speeds.
