Group 1: Energy Storage Station Overview - The energy storage station consists of 216 containers filled with lithium iron phosphate batteries, capable of charging 800,000 kWh within 4 hours [4]. - This facility is designed to act as a "regulator" for the power grid, storing energy during low demand or excess renewable generation and releasing it during peak demand [8]. Group 2: Importance of Energy Storage - Energy storage systems are essential for addressing the challenges posed by the intermittent nature of renewable energy sources, ensuring the safe and stable operation of the power system [6]. - The storage station enhances power supply reliability and improves grid operation efficiency by implementing a "peak shaving and valley filling" strategy [8]. Group 3: Role in Renewable Energy - The energy storage station serves as an optimal partner for green electricity, facilitating the transfer of surplus renewable energy to peak usage times, thereby maximizing the utilization of green energy [10]. - Various energy storage technologies, including compressed air storage, sodium-ion storage, and all-vanadium flow batteries, are being explored and applied in Gansu, contributing to the achievement of carbon neutrality goals [12][13].
