A device, comprising:

• an integral AC frequency measuring unit;
• one or more integral AC power measuring units;
• an integral calculation unit configured to generate a frequency regulation credit based on signals from said integral AC frequency measuring unit and said one or more integral AC power measuring units, said integral calculation unit connected to said integral AC frequency measuring device and to said one or more integral AC power measuring devices;
• an integral frequency regulation credit display connected directly to said integral calculation unit and configured to display an accumulated frequency regulation credit, or an integral memory unit configured to store said accumulated frequency regulation credit, or both said integral frequency regulation credit display and said integral memory unit;
• and
• a case, said case containing said an integral AC frequency measuring unit, said one or more integral AC power measuring units, said integral calculation unit, said integral frequency regulation credit display and said integral memory unit.

A computer system comprising a processor, an address/data bus coupled to said processor, and a computer-readable memory unit coupled to communicate with said processor, said memory unit containing instructions that when executed by the processor implement a method for frequency responsive load management using frequency regulation credits, said method comprising the computer implemented steps of:

• receiving from an AC frequency measuring device, a current AC frequency on an AC power line;
• receiving from a power consumption measuring device, a current power consumption on said AC power line over a period of time equal to a sampling interval;
• calculating a power consumption moving average of a last N power current power consumptions measured, where N is a positive integer greater than 1;
• generating credits, debits or credits and debits based on said current power consumption, said current AC frequency and said power consumption moving average;
• adding said credits, debits or credits and debits to a frequency regulation credit, storing said frequency regulation credit on said memory unit;
• and
• for each next sampling interval repeating said steps of receiving from said AC frequency measuring device said current AC frequency on an AC power line, receiving from said power consumption measuring device said current power consumption, calculating said power consumption moving average, generating said credits, debits or credits and debits, adding said credits, debits or credits and debits to said frequency regulation credit, and storing said frequency regulation credit on said memory unit.

A device, comprising:

• an integral frequency regulation credit display connected directly to said integral calculation unit and configured to display an accumulated frequency regulation credit, or an integral memory unit configured to store said accumulated frequency regulation credit, or both said integral frequency regulation credit display and said integral memory unit, and
• wherein:
• said frequency regulation credit is increased when said current power consumption is driving said AC power line toward a nominal AC frequency of said AC power line;
• said frequency regulation credit is decreased when said current power consumption is driving said AC power line away from said nominal AC frequency;
• and
• said frequency regulation credit is unchanged when an AC frequency of said AC power line is between an upper threshold frequency and a lower threshold frequency.
