Abstract
A power control device for use in an AC power grid for regulating an electrical power a load that is supplied by the AC power grid consumes. The power control device has a frequency sensing functional block for detecting a rate of deviation of the grid frequency from a nominal grid frequency and a logic functional block for performing a load shedding process during which the power the load consumes is reduced. The load shedding process is characterized by parameters, the logic functional block controlling one or more parameters of the load shedding process at least in part on the basis of the rate of deviation of the grid frequency.
