It is reported that on December 7, with the smooth connection of my country's first batch of Shagehuang large-scale wind power and photovoltaic base projects to the grid, the new energy installed capacity of the Northwest Power Grid exceeded 200 million kilowatts, accounting for nearly 50% of the total installed capacity of the Northwest Power Grid. It has doubled again in three years. Now, Northwest New Energy is accelerating its move towards the main power source, further promoting the construction of Northwest's new power system.

In recent years, the development of new energy in the northwest region has accelerated, and the proportion and growth rate of new energy installed capacity have remained leading. In terms of improving the ability to understand system characteristics, we vigorously promote the actual measurement and modeling of new energy stations, carry out full electromagnetic transient digital simulation analysis of large power grids suitable for the high proportion of new energy in northwest China, and greatly improve the delivery end of high proportion of new energy. Large power grid system characteristics cognition and simulation analysis level. In terms of improving the active support capabilities of new energy, the country's first initiative to optimize the transient performance of new energy has been carried out. The scale of UHV DC near-field transformation in Shaanxi, Wuhan and Qingyu has exceeded 15 million kilowatts, and the cumulative output of new energy has increased by 5.2 million kilowatts.

In terms of improving the level of lean control, the company pioneered data-driven new energy centralized transmission cascade section typical method extraction and quota customization technology, which has been deeply applied in areas such as the Xinjiang-Northwest Network Channel, and has increased the transmission capacity of the network channel by 1.6 million kilowatts. The channel utilization rate is about 8 percentage points. In terms of improving scientific and technological innovation capabilities, it took the lead for the first time in the State Grid Corporation of China's new solar energy system science and technology research action plan, innovative research on improving the transient support capacity of high-proportion new energy at the transmission end, and overall planning to solve the temporary problems of high-proportion new energy and ultra-high voltage DC coupling systems. Stability issues.

At present, Northwest Power Grid has achieved "three improvements" in new energy power generation, utilization rate and power generation proportion for seven consecutive years, and key indicators such as installed capacity penetration rate, power penetration rate and power generation proportion have overall reached "three leading" levels.
