戈壁崛起“能源绿洲”

Core Viewpoint - The establishment of the "Shagohuang" renewable energy base in Hami, Xinjiang, aims to leverage abundant wind and solar resources in desert and Gobi areas, contributing significantly to China's clean energy transition and enhancing energy supply stability [1][2][3]. Group 1: Project Overview - The "Shagohuang" renewable energy base covers an area of approximately 1,651 square kilometers with a total installed capacity of 14.2 million kilowatts [3]. - The project employs a "wind-solar-fire-storage integrated" model, allowing for the complementary operation of various energy sources and storage technologies [3][5]. - Once fully operational, the base is expected to deliver 36 billion kilowatt-hours of green electricity annually through the Hami-Chongqing ±800 kV UHV project [3]. Group 2: Resource Utilization - Hami has a land area of 142,100 square kilometers, with Gobi desert covering 94,600 square kilometers, providing ample underutilized land for large-scale renewable energy development [2]. - The region experiences nearly 200 days of wind speeds exceeding level 8 annually and boasts 3,100 to 3,300 hours of sunshine per year, making it one of the sunniest areas in the country [2]. Group 3: Energy Stability and Storage - The base features the largest "Shagohuang" grid-type energy storage system in the country, designed to ensure the safe and stable operation of the power system [4]. - The grid-type storage system enhances the ability to actively stabilize the grid, addressing the intermittent nature of renewable energy generation [5][6]. Group 4: Economic Efficiency - The project focuses on optimizing technology to enhance power generation efficiency and reduce transmission losses, ultimately providing low-cost electricity to consumers [8]. - The integrated control room allows for real-time monitoring and optimal dispatch of both renewable and coal power, potentially increasing renewable energy absorption capacity by 3% [9][10]. Group 5: Technological Innovations - The base is implementing a medium-voltage direct current system to connect solar power directly, reducing conversion losses and improving stability [11]. - A combined cooling tower system has been introduced, significantly reducing water consumption by over 60% per megawatt-hour of electricity generated [13]. Group 6: Future Implications - The continuous optimization of technology at the base is expected to provide a replicable model for future "Shagohuang" renewable energy projects and contribute to the development of a new power system in China [14].
