"The government has set ambitions goals to increase wind power in China to about 170GW by 2020, and DEC looks forward to doing our part to help reach this target. However, there will be infrastructure and interconnection challenges along the way that must be addressed," said Mr. He, general manager of Dongfang Electrical Machinery Co. "Advanced storage technology continues to show promise as a potential solution to the variability of wind energy generation, and installing this project with A123 will allow us to gain hands-on experience with grid-scale storage systems. Ultimately, we expect this to help us understand how we can leverage larger-scale energy storage deployments to facilitate the rapid adoption of wind energy across China."



This project will be A123's first energy storage system in China, where only about 72 percent of the country's total wind power generating capacity is connected to the power grid, according to data from the China Power Union. This is largely due to the unacceptable Low Voltage Ride Through (LVRT) capability—during periods of low grid voltage, wind farms are disconnecting and are slow to reconnect when voltage increases—and the general lack of ramp management technology, which results in the inability to predict the output of wind farms and leads to grid instability. http://bit.ly/nKXqcU
