Capacity Value of Uninterruptible Power Supply Storage
Pei Yong, Audun Botterud, Ning Zhang, Chongqing Kang
Abstract
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.
