| Abstract |
This paper analyzes the impact of data center load models on the transient stability of power systems. Based on prior research, the study compares the Reference load model with the CLOD and ZIP load models. The ZIP load model tends to represent transient stability too optimistically when compared to the Reference load model, while the CLOD model tends to be slightly more conservative. The results show that the cooling load has the greatest impact on the CCT difference between the CLOD and Reference models, indicating that the dynamic characteristics of the cooling load have a significant effect on CCT. This paper emphasizes the importance of accurately modeling the cooling load in data center load models, highlighting that the ZIP model tends to overestimate transient stability, while the CLOD model provides a more balanced, realistic representation. The accurate modeling of cooling loads is essential for ensuring reliable data center operations and stability analysis in power systems. |
