Considering Waste Heat Reuse Data Center Energy System Planning

With the introduction of the national “double carbon” goal and the advancement of new power systems, the energy-intensive data center(DC) industry is encountering increasingly stringent demands for energy efficiency and carbon reduction. This paper addresses the issues of high emissions, excessive energy consumption, and elevated costs associated with traditional DC energy supply systems(DC-ESS) by proposing a planning method for an IES that incorporates waste heat recovery. This approach facilitates the complementary use of cooling, heating, and electricity, leading to a significant enhancement in energy utilization efficiency and a reduction in energy waste, ultimately aiming for the efficient operation of DC. The findings indicate that by recovering secondary energy released from the DC, primary energy consumption is decreased, which greatly enhances the system's economic viability.
