Wind power transmission rate of Gansu Power Grid increased by 270% in the previous October

Summary: Since the beginning of this year, the Gansu Provincial Electric Power Company has accelerated the construction of the 750-kilovolt power grid in Hexi and strengthened the research on wind power technology to effectively improve the capacity of wind power transmission. From January to October, the wind power output from Gansu Power Grid exceeded 6 billion kilowatt-hours, an increase of 270% over the same period of last year.

The Gansu company researched and developed a wind power prediction system with real-time monitoring of wind energy, short-term and ultra-short-term prediction functions to mitigate the impact of large-scale wind power fluctuations and randomness on the power system; large-scale cluster wind power active intelligent control system, real-time monitoring system Trends and wind farms contribute to the rational adjustment and control of wind farms and conventional power generation output, optimize the power system operation mode, to achieve the maximum total wind power output in Jiuquan and open, fair scheduling. After the project was put into operation, the calculation results showed that wind power generation on the grid increased by 7.05%, and the cumulative increase in power generation was 142 million kwh.

In addition, the Gansu company analyzed Jiuquan wind power resources and output characteristics, completed a large-scale wind power transmission and absorption related technology research, wind power companies to detect wind turbine low voltage ride through capacity transformation effect, help wind turbine manufacturers, wind power companies to improve fan low voltage ride through capability.

It is reported that during the year and in the first half of next year, the Gansu Company will also launch the “National Research and Development of Cluster Control System for Wind Farms and Photovoltaic Power Plants” and “Key Technology and Demonstration Application of Grid-Friendly New Energy Generation”.
