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: Techniques for providing power to a data center includes transferring heat from a computer data center to warm a fluid stored within an energy regeneration system; circulating the warmed fluid to a flow of compressed gas stored within the energy regeneration system during a discharging process that expands the compressed gas; generating energy with the energy generation system from the discharging process; and providing at least a portion of the generated energy to the computer data center as electrical power.

Abstract: A thermostat management server may include one or more processors and one or more memory devices comprising instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising receiving information that characterizes energy usage associated with the plurality of thermostats, receiving parameters characterizing proposed future demand-response events, selecting a combination of thermostats from the plurality of thermostats for which the energy usage can be reduced, simulating a demand response event based on the parameters and using different weather conditions for the combination of the plurality of thermostats, generating statistical probabilities of meeting a plurality of capacity reduction levels based on the different weather conditions, selecting a capacity reduction level from the plurality of capacity reduction levels based on the statistical probabilities, and sending the capacity reduction level to the utility provider computer system.
