Forecast of Energy Storage Applied in Wind Power Integration

Now, the wind power in China develops quite rapidly and the installation of wind power is accounting more and more in power generating installation. Wind power, as a typical kind of renewable energy, is intermittent and unstable so that causes concerns about the damage it may do to power grid when integrate the large-scale wind power. According to that, integration is the main restraint for China to develop wind power. Energy storage, as an emerging technology, has been applied, tested and operated for a few years. It can solve integration problem efficiently and improve the efficiency of wind power integrating with the power grid. Hence, there is a large demand of energy storage on the wind power market. This paper chose grey forecast method to predict the installation of wind power in the near future. Then based on the forecast result, this paper selected low, medium and high rate of energy storage for the wind power system, and finally it predicted the demand of energy storage in the wind power integration from 2012~2015. This paper provided quantitative number and made it possible to plan further development.
