摘要：
Uninterruptible power supply (UPS) storage facilities deployed on the demand side have spare capacity that could be used to participate in power system operation. However, their capacity contributions to a power system's load-carrying capability have not been appropriately recognized. This letter exhibits the insight that UPS storage can serve loads during power shortages and therefore has a capacity value. Thus, we propose a novel capacity value evaluation framework applicable for UPS storage. The framework can evaluate the capacity contributions of massive distributed UPS storage facilities while effectively considering their chronological operational characteristics.
