1. An intelligent load management unit controller (ILMUC) for facilitating power factor correction (PFC) in an electrical power system having a plurality of other ILMUCs, said ILMUC comprising: one or more switches configured to switch current from a system power supply to a load in an electrical power system, said one or more switches configurable to being switched in accordance with a plurality of different switching configurations and under a plurality of different system load conditions; and a controller configured to determine and report a current waveform pattern descriptive of the waveform of current flowing through the ILMUC's load over a single or multiple alternating current (AC) cycles to a central power management server, which determines, by comparing the reported current waveform pattern to current waveform patterns determined and reported by one or more ILMUCs of said plurality of other ILMUCs in the electrical power system associated with other loads, an optimum switching configuration for the one or more switches to adapt to, said optimum switching configuration comprising a switching configuration that maximizes a power factor of said electrical power system.
