Wind and photovoltaic energy production are time-sensitive and accidental. If there are clouds or the wind stops, wind and photovoltaic power generation will have to stop, but charging cannot stop, so the power grid must start immediately. thermal units to fill the gap, but it will stop completely. It takes several hours for a thermal power generation unit to start up, so to be able to fill the gap immediately, some units must operate at low load. to be able to deal with this situation. However, these capacities are limited, so the electricity grid must limit the production of wind and photovoltaic energy according to reserve capacity.
1. The first type of photovoltaic wind power regions based on wind volume is as follows. as follows: Inner Mongolia Autonomous Region, except Chifeng and Tongliao cities,Xing'an League, and other areas outside Hulunbuir City: Urumqi City in Xinjiang Uygur Autonomous Region, Ili Kazakh Autonomous Prefecture, Changji Hui Autonomous Prefecture, Karamay City and Shihezi City.
2. The regions of the second type of Volt wind power are as follows according to wind volume: Zhangjiakou City and Chengde City in the Northern Province: Chifeng City, Tongliao City, Xing'an League and Hulunbuir City. in Inner Mongolia Autonomous Region: Zhangye City and Jiayuguan City in Gansu Province, Jiuquan City.
