Abstract:

With the rapid expansion of internet data centers (IDCs), the deployment of uninterruptible power supply (UPS) systems in IDCs has seen significant growth. Despite their critical role, UPS battery systems remain largely underutilized, being active only during infrequent power outages. This paper advocates for the enhanced utilization of the energy storage capabilities of UPS battery systems, promoting an economical and efficient approach to energy management without compromising backup power reliability. We introduce an advanced architecture for energy storage type of UPS (EUPS), delineate control strategies for its diverse energy storage applications, and present a framework for its integration into multiscenario power grid regulations through coordinated control strategies. The efficacy of the proposed EUPS system architecture and control methodologies is substantiated through a fully operational EUPS demonstration system.

Key words: energy storage type of UPS, internet data center, frequency regulation, peak valley regulation, coordination control
