China News Service, Xining, November 9th (Li Jiangning, Wang Guodong, Lu Guoqiang) According to China State Grid (hereinafter referred to as State Grid) Qinghai Electric Power Company on the 9th, on November 8th, the first 10 million-kilowatt new energy base in Qinghai Hainan The batch of 11 new energy distributed dimming cameras have all been put into use, marking the official formation of the world's largest new energy distributed dimming camera group, which can boost the local new energy consumption capacity by 1.85 million kilowatts.
Qinghai Power Grid is the provincial power grid with the highest proportion of new energy installed capacity in China.
In view of the large installed scale and high proportion of new energy in Qinghai and Hainan, the small installed scale of conventional power supplies and relatively weak voltage support capabilities, in order to further explore and solve the technical problems that restrict the large-scale development and utilization of new energy, the national power dispatch control The center, together with the planning and design department, the Northwest Branch of the State Grid, Qinghai Electric Power, the relevant scientific research institutes, and the owners and manufacturers of new energy stations, proposed four new energy collection stations in Xinyang, Xiayang, Xuming, and Zhuyu in Hainan, Qinghai. The solution of installing 21 distributed dimming cameras will greatly improve the level of new energy transmission under the premise of ensuring the safe and stable operation of the power grid.
"This is the first time in the world to explore the large-scale installation of distributed dimming cameras on the power supply side. It has important demonstration and leading value for promoting the large-scale development and utilization of new energy and building a clean, low-carbon, safe and efficient energy system." According to the National Electric Power Dispatching Control Center Dr. Zhang Yi introduced that, compared with traditional reactive power compensation devices, distributed dimming cameras have the advantages of strong voltage support at the moment of failure and fast transient response. They can be used as stabilizers on the power supply side of the power system. An important part of energy power system.
It is reported that the Qinghai Hainan Distributed Distributed Camera Project officially started equipment installation in May 2021. State Grid Qinghai Electric Power Company actively coordinated with all parties to comprehensively promote the distributed controller for network connection, commissioning, grid connection test and operation management, etc. The work effectively guaranteed the smooth grid connection of the first batch of 11 distributed dimming cameras.
According to the construction plan, by the end of 2021, all 21 distributed cameras are planned to be put into production. By then, the new energy transmission capacity in Qinghai and Hainan will be increased by 3.5 million kilowatts. 10,000 tons, reducing carbon dioxide emissions by 5.742 million tons, with significant energy-saving and emission-reduction effects.
