Sudden and short-duration power swings in modern supercomputers can have a challenging impact on the voltage of the adjacent power grids. The coming age of exascale supercomputers is expected to bring platforms that are capable of power fluctuations of up to 20 MW in 15 milliseconds (ms) or less (one cycle at 60 Hz). This paper presents a framework that explains these relationships between rapid power flow changes in high performance computing environments (HPC) and power grid characteristics, such as voltage and frequency fluctuations, and offers insights on system improvements that can mitigate large power disturbance issues.
