Abstract: 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.

Abstract: Systems and methods for managing power loads of one or more data centers using a wide-area energy controller to operate local energy resources of the data center based on power control information generated by a remote data center control system are described. In one aspect, a system includes a set of local energy sources configured to provide power to the loads of the energy system and a wide-area energy controller. The wide-area energy controller includes a first interface communicably coupled to an application programming interface (API) that connects a remote data center control system to respective wide-area energy controllers of multiple data centers, the first interface being configured to receive power control information from the remote data center control system via the API. The wide-area energy controller includes a control unit configured to schedule the local energy sources to provide power to the loads based on the power control information.
