My comment from another thread on this issue;
“Heres a very important point from the article. The power generated is not usable at this time, and no answer is in sight.
In contrast to a steady one-source input, like from a nuclear or coal-fired power plant, a wind farm has many smaller sources with the output of each constantly varying with conditions like wind direction, wind speed and blade angle. Such variations lead to destabilizing energy-oscillations in the whole system that cannot be handled by the current converters. To make matters worse, the engineers have yet to fully understand the nature of the problem and to come up with any solution for it.
Large Batteries make swell flux capacitors.
There are wind farms all over the world. Do they all have this problem?
