The integration of highly uncertain renewable energy into the grid poses significant challenges to the secure operation of virtual power plants (VPPs) that include data centers. To address this issue, this paper proposes a distributionally robust optimization (DRO) scheduling model for data center VPPs based on a diffusion model. First, to more accurately characterize the uncertainty of photovoltaic (PV) power generation, a diffusion model is employed to generalize irradiance-temperature joint scenario data, enhancing both the accuracy and diversity of PV output data. Then, a Gaussian mixture clustering model is applied to reduce the dimensionality of PV output data, and the resulting scenarios are used as the initial set for DRO. Furthermore, to further explore the demand response potential of data centers, a mathematical model for data center VPPs incorporating transferable batch processing loads is developed. Finally, the min-max-min DRO problem is solved using the column-and-constraint generation algorithm. Simulation results demonstrate that the proposed diffusion model-based PV output scenario generation method in this paper can more accurately and effectively capture the uncertainty of PV. Additionally, the proposed DRO model in this paper can effectively balance the relationship between economic operation and robustness. %K 扩散模型， %K 数据中心， %K 虚拟电厂， %K 分布鲁棒优化， %K 辐照度– %K 温度联合场景， %K 列和约束生成算法
