Abstract: A method, apparatus, and system for disconnecting loads from the electrical grid are disclosed. An application programming interface (API) frontend of an advanced metering infrastructure (AMI) load shedding system may receive a load shedding activation command; in response to receiving the load shedding activation command, the API frontend may deploy a load shedding token to one or more electricity meters of the AMI load shedding system, and cause the one or more electricity meters to disconnect corresponding loads from the one or more electricity meters.

Abstract: A method, apparatus, and computer-readable storage medium for detecting voltage anomaly in an electrical grid are provided. An electricity meter may collect voltage data by sampling a voltage waveform of the electrical grid at a preselected sampling rate; based on the voltage data, determine standard voltage waveform statistics of voltage of the electrical grid including statistical metrics; determine a range for the statistical metrics based on the standard voltage waveform statistics; at a preselected interval, calculate a statistical value of the statistical metrics of a present voltage waveform sampled at the preselected sampling rate for a preselected interval of the present voltage waveform; and in response to determining that the statistical value is outside of the range: capturing a predetermined number of cycles of voltage waveforms around the present voltage waveform, and sending an alarm to a remote computing device associated with the electrical grid.
