Abstract

Aiming to address the problems of excessive energy consumption, high emission and significant cost of data centers, this study proposes an integrated energy system for adata center with solar energy and natural cooling source combined with hydrogen storage, which integrates photovoltaic module, collector, internal combustion engine, absorption refrigeration unit, and fuel cell. System configuration and operating parameters are optimized using a two-layer optimization method. In the upper layer, a non-dominated sorting genetic algorithm is adopted to optimize the system capacity, In the lower layer, a multi-objective grey wolf optimization algorithm is used to optimize the ratio of operating equipment output. System performance is significantly improved by weighing the multi-dimensional indicators of energy efficiency, economic benefit, environmental protection, system independence, and sustainability. Through optimization, primary energy conservation rate reaches 46.33%, annual cost efficiency rate is 38.25%, CO₂ emission saving rate is 49.08%, grid integration level is 56.07%, annual total operating cost is $ 3.41×10⁵, and carbon usage effectiveness is 0.62. This study provides a new idea and method for the planning and design of data center energy systems by flexibly adopting multiple energy supply strategies.
