摘要： In general, one innovative aspect of the subject matter described in this specification can be embodied in a load control system configured to perform load control operations comprising: measuring a voltage on an electrical grid at a plurality of times; determining, for each time of the plurality of times, a difference between a specified normal voltage and the respective measured voltage at that time; summing the differences between the specified normal voltage and the measured voltages to determine a curtailment level; determining whether the curtailment level exceeds a first threshold curtailment level; and in response to determining that the curtailment level exceeds the first threshold curtailment level, adjusting an amount of power drawn by a load.

摘要： Methods, systems, and apparatus for circuit breakers with integrated safety, control, monitoring, and protection features. In one aspect, a circuit breaker includes, an input and an output, a switch coupled between the input and the output, a sensor configured to measure the current flowing from the input to the output, and a control system coupled to the sensor and the switch, wherein the control system is configured to perform operations including comparing a rate of change of the current measured by the sensor to a threshold rate of change of current, determining that the rate of change of the current measured by the sensor exceeds the threshold rate of change of current for at least a predetermined period of time, and as a consequence of determining that the rate of change of current exceeds the threshold rate of change, opening the switch, thereby disconnecting the input from the output.
