Patent ID: 8341442

Claim:
A modification method comprising: detecting, by a computing system, a frequency signal associated with an input voltage signal used for powering a plurality of power consumption devices at a specified location; monitoring, by said computing system, said frequency signal; first comparing, by said computing system, said frequency signal to a predetermined frequency value; determining, by said computing system based on said first comparing, that said frequency signal 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; enabling, by said computing system based on results of said second comparing, a load adjustment modification process associated with said plurality of power consumption devices at said specified location, wherein said enabling is executed after a specified time delay period, wherein said results of said second comparing indicates that said first value exceeds said predetermined frequency value by more than said second value, and wherein said load adjustment modification process comprises: determining, by said computing system, a desired load increase value associated with reducing said first value by a specified amount; determining by said computing system, a specified time period associated with achieving said desired load increase value; enabling for said specified time period, by said computing system based on said desired load increase value, a first power consumption device of said plurality of power consumption devices such that said first power consumption device consumes power from said input voltage signal; and third comparing, by said computing system, a first current load value on said input voltage signal to said desired load increase value; generating, by said computing system a report associated with said load adjustment modification process; and storing, by said computing system, said report.
