1. A method to regulate a power grid, comprising:
receiving, by operation of a device connected to the power grid, a frequency limit and a voltage limit sent by a load manager;
measuring, by operation of the device, a frequency of a power main and a voltage of the power main;
comparing, by operation of the device, the measured frequency to the frequency limit and the measured voltage to the voltage limit;
calculating, by operation of the device, an adjustment to an electrical load of the device based at least in part on the comparing;
adjusting, by operation of the device, the electrical load of the device;
sending, from a plurality of devices connected to the power grid including the device connected to the power grid, data indicating a capacity for load-change to the load manager:
receiving, at the plurality of devices connected to the power grid including the device connected to the power grid, at least one revised device configuration based at least in part on the capacity for load-change; and
changing, at the plurality of devices connected to the power grid including the device connected to the power grid, electrical demand from the power grid.
