Core Viewpoint - The article emphasizes the importance of Inner Mongolia's clean energy resources and the development of a stable and reliable power grid system to efficiently transmit this energy across the country, aligning with the "14th Five-Year Plan" for a clean, low-carbon, safe, and efficient energy system [1][3]. Group 1: Energy Infrastructure Development - Inner Mongolia is the largest province in China for installed renewable energy capacity, playing a crucial role in supporting the national power grid during peak demand periods [3]. - The Zhangbei-Success 1000 kV UHVAC project is set to be operational by October 31, 2024, establishing a UHV transmission corridor between two key substations, enhancing the safety and stability of power transmission [5][7]. - The project will expand the UHV substation capacity by 9 million kVA, enabling the transmission of over 70 billion kWh of electricity annually, equivalent to the annual consumption of 19 million households, with 72% coming from renewable sources [7]. Group 2: Technological Innovations and Challenges - UHV technology is critical for reducing power losses during long-distance transmission, as it allows for higher voltage and lower current, minimizing heat losses [3]. - The development of GIS (Gas Insulated Switchgear) technology is essential for ensuring the safe and stable operation of the power grid, although pre-warning for GIS faults remains a global challenge [9][11]. - A new panoramic perception laboratory for long-term operation of UHV GIS has been established to simulate typical working conditions and detect internal anomalies, utilizing advanced detection technologies [11]. Group 3: Green Energy Transactions - Inner Mongolia has established itself as the leader in green electricity trading in China, having formed cooperative agreements with eight provinces for green electricity delivery [13]. - The region has developed eight UHV transmission corridors and supporting grid projects aimed at delivering clean energy to North and East China, with a total of 26 UHV supporting facilities under construction during the "14th Five-Year Plan" [14]. - As of now, Inner Mongolia has transmitted over 630 billion kWh of electricity, with approximately 145 billion kWh being clean energy [14].
