Optimal Operation of Smart Cities Integrated with Data Centers and Workload Dispatch

To advance green transformation (GX), the transition to smart cities (SC) is being promoted. For this purpose, an energy management system (EMS) utilizing IoT devices in SCs is a promising approach. In recent years, the proliferation of artificial intelligence and digitalization has led to an increase in data centers (DC). Along the decarbonization pathway, SCs require the introduction of renewable energy and combined cooling, heating and power (CCHP), and integration with DCs is also essential. Therefore, this paper proposes a model that integrates DCs and SCs, comprehensively addressing DC workloads, power, and cooling demands. It incorporates indirect power demand response through the dispatch of delay-tolerant workloads. To validate the proposed model, numerical simulations are conducted, comparing costs and carbon emissions. Case studies compare scenarios involving the standalone operation of SC and DC, as well as their integrated operation. Simulation results indicate that integrating DC and SC reduces costs.
