As an important support technology of renewables, energy storage system is of great significance in improving the resilience of the power system. In this paper, a resilience enhancement method for power systems with high penetration of renewable energy based on underground energy storage systems (UESS) is proposed.
First, underground space can provide a stable and ample operation space for the energy storage system, protecting the devices from the impacts of extreme weather like rainstorms, typhoons, and blizzards (Zhang et al., 2021).
These systems provide numerous benefits, including increased utilization of renewable energy, enhanced grid stability and reliability, ensured energy security, balanced supply and demand, and reduced carbon emissions and environmental impact [9, 10].
