成都作为四川省会及西南电力负荷中心，最高负荷突破2000万kW,但应急备用和调峰电源仅400万kW,电源“空心化”问题突出，电网安全面临严峻挑战。抽水蓄能电站具备顶峰、调峰、调相及黑启动等综合功能，是保障大电网稳定运行的关键支撑。基于成都电网现状，结合网、源、荷发展趋势，剖析电源“空心化”的形成机理及应对策略，并重点探讨抽水蓄能电站在缓解成都电力供需矛盾、增强电网韧性方面的关键作用。

As a major economic and energy province, Sichuan is located at the core intersection of the Western Development Strategy and the construction of the twin-city economic circle in Chengdu and Chongqing, and is accelerating the construction of a national strategic hinterland and a key industrial backup area. As the capital of Sichuan Province and the power load center of the southwest, Chengdu has a maximum load of more than 20 million kW, but the emergency standby and peak adjustment power supply is only 4 million kW. The problem of "hollowing-out" of the power supply is prominent, and the safety of the power grid faces serious challenges. The pumped storage power station is equipped with comprehensive functions such as peak, peak adjustment, phase adjustment and black start, which is the key support to ensure the stable operation of large power grids. Based on the current situation of Chengdu's power grid, this article analyzes the formation mechanism and coping strategies of power supply "hollowing-out" in combination with the development trend of grid, source and load, and focuses on the key role of pumped storage power stations in alleviating the contradiction between power supply and demand in Chengdu and enhancing the resilience of the power grid.
