1. An autonomous load having an input, the autonomous load comprising:
a voltage detection circuit coupled to measure one or more voltage signals at the input of the autonomous load;
an event identification processor coupled to the voltage detection circuit to receive one or more voltage signals measured by the voltage detection circuit and to extracting and identify a load event corresponding to at least one characteristic of at least one of the one or more measured voltage signals, the event identification processor comprising:
a transient identification processor coupled to receive one or more voltage signals from the voltage detection circuit and to extract frequency and voltage harmonic transients from the one or more voltage signals and to identify individual load events corresponding to the extracted frequency and voltage harmonic transients; and
an autonomous load controller coupled to the event identification processor, the autonomous load controller configured to receive load event information from the transient identification processor and in response to the load event information provided thereto, provide a control signal to the autonomous load.
