Energy Management for an Integrated Energy System with Data Centers Considering Carbon Trading

The data center (DC) is a popular candidate for energy management due to its huge energy consumption and great flexibility potentials. In this paper, the energy management for an integrated energy system with loads of DCs (IESD) is addressed, focusing on energy-saving and carbon-reduction. First, the loads of DCs are introduced as integrations of electric and cooling loads, and the IESD is modelled based on a combined cooling, heating, and power (CCHP) system. After that, a low-carbon economic dispatch model is formulated to minimize the operation cost including energy supplying cost and carbon trading cost, taking the unique demand characteristics of loads of DCs into account. Finally, case studies on a six-hub IESD are carried out. Simulation results demonstrate that the proposed method is able to promote the IESD operation with a more economic and low-carbon way.
