Abstract: The exponential growth of digitalization and artificial intelligence workloads has positioned data centers among the fastest-growing electricity consumers worldwide. Traditionally viewed as passive loads, modern data centers possess advanced energy infrastructures, such as uninterruptible power supply (UPS) systems, battery storage, and intelligent cooling, that can be leveraged as flexible resources for smart grid operation. This paper proposes an integration framework between Data Center Infrastructure Management (DCIM) and Smart Grid Energy Management Systems (SG-EMS) to enable bidirectional energy and information exchange. The proposed architecture coordinates local assets within data centers with grid-level control for demand response, peak shaving, and renewable energy utilization. A case study of a 10 MW data center equipped with a 1 MWh battery and 2 MW photovoltaic plant demonstrates that coordinated control can reduce peak grid demand by up to 18%, lower daily energy costs by approximately 17%, and provide sub-second frequency response without affecting IT service performance. The results confirm the potential of data centers to act as virtual energy storage units and active participants in smart grids. Future developments include AI-driven predictive control, digital twins for co-simulation, and secure interoperability between DCIM and SG-EMS platforms.
