Examples described herein include receiving current values of a power device, determining a spike situation of the power device, determining a power course for the power device, and operating the power device according to the power course. The current values may include a first current value at a first time and a second current value at a second time. The power course may be determined based on a plurality of current change values associated with the spike situation, a total number of spikes associated with the spike situation, and a duration of at least one spike out of the total number of spikes associated with the spike situation.
