Abstract:
A mechanism is provided for dynamically changing power caps for a set of powered elements. Current being consumed by the set of powered elements P on a branch circuit is measured and available current on the branch circuit is determined. A new total power cap for a current time period t is identified based on a current total power cap and the measured current. A difference in total power caps (ΔTPC) is determined and, for each powered element p in the set of powered elements P at the current time period, a new power cap PC (p,t) is determined based on the previous power cap PC(p,t−1) and the difference of the total power caps to the set of powered elements P. A power cap of each powered element p is then dynamically set to the new power cap PC (p,t).
