An electric power monitoring system includes a source monitor for measuring momentary
power output of an electric source supplying electric power to a power distribution
system having at least one electric load. The momentary power output is compared
with a reference load capability for the electric source to determine the ability
of the electric source to support additional load, and load capability data is
transmitted based on the load capability. At least one load control receives the
transmitted load capability data and controls the supply of power to the at least
one corresponding electric load based on the load capability data.
