Abstract:
1. A power demand modification method comprising: receiving, by a computing system, a frequency signal value from a power transmission grid, wherein said frequency signal value is associated with a frequency signal associated with an alternating current (AC) input voltage signal retrieved from said power transmission grid, and wherein said AC input voltage signal is used for powering a plurality of power consumption devices at a specified location; monitoring, by said computing system, said frequency signal value; first comparing, by said computing system, said frequency signal value to a predetermined frequency value; determining, by said computing system based on said first comparing, that said frequency signal value comprises a first value that is not equal to said predetermined frequency value; calculating, by said computing system, a difference value between said first value and said predetermined frequency value; second comparing, by said computing system, said difference value to a second value, wherein said second value comprises a frequency offset value; enabling, by said computing system, a connection to an uninterruptable power supply (UPS); enabling, by said computing system based on results of said second comparing, a power demand modification process associated with using said UPS to modify a power demand on said AC input voltage signal; generating, by said computing system a report associated with said power demand modification process; and storing, by said computing system, said report.
