Successful development of wind power forecasting system

10-06-22

National Grid has been regarded as "rubbish" of wind power, suddenly become "hot demand."

Wind generators speed Internet access in the same time, directly under the China State Grid Power Research Institute has developed for the electric power grid dispatching wind forecasting system, and accelerate the roll out in the grid extension.

"To improve the use of time and access to wind power capacity must be used in the scheduling side wind power prediction system." Enhanced North China Electric Power University, said meters.

As the national grid behind the powerful promoter, promoting Power Research Institute's forecasting system can be described as smooth sailing, and wind power companies are starting more and more worried, would fall into the power grid control.

Control wind

Prediction System Power Research Institute Science network has penetrated into the province's power generation plans under development.

February 20 this year, National Grid issued a "wind-power forecasting system functional specification," and demanded access to wind power forecasting functions must have.

Currently, the system has been in Jilin, Jiangsu, Ningxia, northwest, Gansu, Liaoning power grid into operation, the Northeast and Heilongjiang grid wind power forecasting system being system debugging, Xinjiang, Shanghai, Zhangjiakou grid wind power generator forecasting system being forecast modeling. Led development of this system is responsible for the national network of wind power experts, Huizhu that application of the system's network to 11 provinces, the total number of forecast wind fields more than 80, with a total installed capacity of wind power forecasts more than 6 million kilowatts.

Energy Power Research Institute in the new joint venture by the Dongrun ring will introduce the system of material was clearly written, Power Grid Corporation Hui Purchase Forecast Zhunque of wind power, limit the wind farm power prediction Buzhun or take penalties Cuoshi .

"To improve the use of time and access to wind power capacity must be used in the scheduling side wind power prediction system." Enhanced North China Electric Power University professor meters, said, "Now, this work only two units, North China Electric Power University, China Power Research Institute conducting research and testing. "

It is understood by the national power Long Yuan Wind Power Company commissioned, North China Electric Power University, developed the system in the country Longyuan Kawai wind power put into trial operation, and is Weihai, Chengde develop wind farms and other places debugging.

North China Electric Power University professor Liu Xingjie said prediction system put into operation, so Longyuan wind power generation efficiency of at least doubled. "This is just calculate the wind field itself due to the use of the system to achieve results, but also multiple access to the Internet did not calculate power." Liu Xingjie said.

However, this part of the issue over to the power of china wind generators has not authorized, Inner Mongolia Electric Power Dispatching Center refused to recognize and statistical forecasting system by a set of wind power generating capacity increased. Does not recognize the reason is the Inner Mongolia Electric Power Company to use its development of wind power forecasting system for the whole network will wind up unified control.

For the same purpose, the State Grid Power Company as the center in order to extend the prediction system, we request that wind power companies will own all the core data reported to the Power Grid.

According to the detailed requirements specifications, system requirements for power companies forecast wind power to provide history, historical wind towers, historical numerical weather prediction, detailed information on wind power group, running six data records and topography.

An anonymous engineer of Hebei Wind Farm, said: "These are our trade secrets. This standard is to make us their arms, put all their secrets to the unconditional power, in exchange for more power generation schemes. this continues we not become a power-controlled enterprise. but in order to generate electricity, no way. "

Contradiction

Although wind power generators is now the national grid on the enthusiasm high, but power generation groups in Inner Mongolia, Gansu, the beginning of construction of wind power, the country does not support network. The power company also wind power as "spam," trying desperately to reduce and limit wind power online.

EPRI vice president of new energy by working late Wing Ning said that as wind power is intermittent. This "wind and electricity, no wind, no power," power, which makes the wind power output will change with the occurrence of external energy fluctuations, fluctuations. Fluctuations in wind power will impact.

"Wind power trouble is technically and wind turbines economically resolved." North Dianlitaixue of wind power in the Ph.D Yu Yang said, wind power Bingbu terrible, "Dianwangwanquan have capacity to accommodate this Bufen digestive power, Wu Xu Ewaixiujian The new power plant, the cost increase only moderately. "

China State Grid Power Research Institute has commissioned 10 million kilowatts at the Jiuquan wind power base in site visits and testing, Huizhu participated in this trial, "Jiuquan planning is 12 million kilowatts, currently under construction, 500 million kilowatts, but we test The result is that when more than 4 million kilowatts of wind power to grid, cause voltage instability, leading to the collapse of the western power grid. "

Yu Yang that, the national grid is now eager to Jiaqiang right uncontrolled development of wind power's Guan Li, Tong Guo Zhidingruogan You Keneng in law's policy on wind power to run, and Wang, Tiaoduojinhang control.
