64.23GW！国家电网开展大规模新型储能集中调用，顶峰能力堪比3座三峡

Core Viewpoint - The article highlights the significant role of new energy storage systems in supporting the power supply during peak demand periods, showcasing their capacity and effectiveness in various regions across China [1][4][5]. Group 1: New Energy Storage Capacity and Performance - As of now, the maximum adjustable power of new energy storage in the operational area of the State Grid Corporation has reached 64.23 GW, with a real-time maximum discharge power of 44.53 GW, marking a 55.7% increase compared to the same period last year [1]. - During the peak summer period, new energy storage systems have demonstrated the ability to fully utilize their capacity in regions like Jiangsu, Fujian, Hubei, Shanxi, and Tianjin, significantly enhancing power supply capabilities [1]. - In Jiangsu, 93 new energy storage stations achieved a maximum discharge power of 714 MW, accounting for 94% of the installed capacity of new energy storage in the province [3]. Group 2: Importance of New Energy Storage in Power Systems - New energy storage is identified as a key technology for building a new energy system and power grid, capable of flexibly responding to grid demands and playing a role in peak shaving and valley filling [1]. - The peak capacity of new energy storage during the summer evening peak is equivalent to nearly three Three Gorges hydropower stations, providing substantial support during high electricity demand periods [1]. - The development of new energy storage is crucial for optimizing the allocation of power resources and promoting the advancement of storage technology, which is essential for the construction of a new power system [4]. Group 3: Regional Initiatives and Achievements - In Yunnan, a large-scale concentrated charging and discharging test was conducted, achieving a maximum charging power of 479 MW and a maximum discharging power of 474 MW, with utilization rates of 96% and 95% respectively [5]. - Yunnan has surpassed 5 million kW in new energy storage installations, ranking first among the five southern provinces, significantly enhancing the region's power system regulation capabilities [5]. - The next steps for Yunnan's power grid company include utilizing market mechanisms for scientific deployment of new energy storage systems to enhance supply security and promote clean energy consumption [5].
