Abstract

Abstract:

The security and stability of a power system can be compromised by the output fluctuation brought by wind power grid-connection. Thus， considering the uncertainty of wind power prediction，a wind power output fluctuation suppression model is proposed based on a data center's delay calculation. The model is divided into two stages. In the first stage，based on the predicted wind power output，the data center load curve need to be smoothed in the premise of fluctuation suppression.In the second stage，the scheduling scheme is adjusted to meet the wind power output suppression requirements under the worst scenario. The simulation results on the practical case show that the proposed model can suppress the wind power output under the worst scenario. The suppression method that takes wind power uncertainty into consideration is more reliable than that does not.

Key words: wind power generation, fluctuation suppression, data center energy consumption, wind power uncertainty, robust optimization, carbon neutrality, new power system
