Owing to the stochastic nature of wind speed, time-variable of parameters, system lagging and system nonlinearities the power generated by wind turbines changes rapidly.

由于风速的随机性、风电机组参数的时变性和系统的非线性，以及系统的复杂性引起的时滞性，造成风电机组输出功率的不稳定。

Because of the physics of how force is generated by wind blowing past a sail, tall thin sails generally have more power when the boat is sailing into the wind.

根据风吹过船帆时产生动力的物理原理，当船只航行在风里时，高而薄的帆通常产生更大的力。

The apartment is powered by solar panels and an unspecified source of wind power. It relies on an array of fuel cells to store the generated electricity.

房子主要由太阳能电池板和不知何处而来的风能供电，并装有一排燃料电池储存电力。

The pump storage hydro scheme is designed to "soak up" excess power generated by wind and wave farms, using it to pump water up to a reservoir.

As more turbines are approved, the National Grid is legally obliged to extend the power infrastructure - and that's why there are plans for pylons and a sub-station to be built in Powys so that the power generated by wind farms is taken to the rest of the country.

BBC: What are the wind power issues?

If the wind intensifies very quickly, the amount of power generated by the wind turbines increases rapidly, injecting excess power into the generation system.
