Abstract: The present disclosure relates to a computationally efficient technique for determining loads to shed based on both active and reactive power. For example, a monitoring and control system may receive electrical measurements of a power system. The monitoring and control system may determine an active power and a reactive power of each bus in the power system based on the received electrical measurements. The monitoring and control system may send a command to trip at least one breaker to cause the at least one breaker to shed a load based at least in part on both the active power and the reactive power consumed by each bus in the power system.

Abstract: The present disclosure relates to shedding loads based on perturbation of active power and perturbation of reactive power. For instance, a method includes receiving electrical measurements of a power system. The method includes detecting a contingency in the power system. The method includes determining perturbation of the active power and perturbation of reactive power in the power system based on the electrical measurements. The method includes shedding one or more loads of the power system due to the contingency based on the perturbation of the active power and the perturbation of reactive power.
