With the launch of a new generation of new-energy power prediction system which includes artificial intelligence (AI) technologies, the electricity production from renewable energy sources in Northwest China’s Xinjiang Uygur Autonomous Region now has been equipped with a “weather forecast” function which can help keep up to date with energy output and electricity generation for a period of time in the future.
By integrating AI and other technologies into the new-energy power prediction system, a more refined prediction model can be established to improve the accuracy of power prediction according to the differences in Xinjiang’s terrain, wind and solar resources, and power generation characteristics, said the State Grid Xinjiang Electric Power Co.
Thanks to the advanced technologies, the accuracy rates of ultra-short-term, short-term and medium-term forecasting of wind power in Xinjiang can reach 96 percent, 92 percent, and 81 percent respectively, exceeding the national standard. The prediction accuracy of photovoltaic power generation in each period could reaches about 98 percent, data from the company showed.
There are 618 new-energy stations in Xinjiang that have so far connected to the new generation of power prediction system.
The updated system using AI and other technologies is quite powerful as it can not only provide accurate data support for grid development planning and various power generation plans, but also scientifically optimize the maintenance plan of power transmission and transformation equipment and conventional power supplies, and expand transactions in the power market, a representative from the State Grid Xinjiang Electric Power Co said.
Xinjiang has outstanding natural resource advantages, and its reserves of wind energy resources rank among the strongest in China.
China has been steadily forging ahead with renewable energy development amid its transition to a low-carbon economy, striving to meet peak carbon dioxide emissions by 2030 and achieve carbon neutrality by 2060.
In 2021, China generated 2.48 trillion kilowatts of electricity from renewable energy sources, which accounted for 29.8 percent of the country’s total electricity consumption. Wind farms and photovoltaic stations both saw capacity exceed 300 million kilowatts, data from the National Energy Administration revealed.
