Abstract

A method supplying AC power and billing a customer using frequency regulation credits. The method includes using an AC frequency measuring device, measuring a current AC frequency on an AC power line; using a power consumption measuring device, measuring a current power consumption on the 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 or debits based on the current power consumption, the current AC frequency and the power consumption moving average; adding the credits or debits to a frequency regulation credit; and for each next sampling interval repeating measuring the current AC frequency, measuring current power consumption, calculating the power consumption moving average, generating the credits or debits, and adding the credits or debits to the frequency regulation credit.

Claims

1. A power and frequency regulation meter to which AC power is supplied from an AC power supplier through an AC power line, said power and frequency regulation meter comprising:

a case;

an AC frequency meter that receives AC power from the AC power line;

an AC power consumption meter that receives AC power from the AC power line;

an AC power consumption display that receives AC power from the AC power line and displays power consumption;

a frequency regulation credits display that displays a frequency regulation credit;

a processor to which the AC frequency meter, the AC power consumption meter, AC power consumption display, and frequency regulation credits display are coupled;

a memory device coupled to the processor; and

a communication device coupled to the processor,

wherein the case encases the AC frequency meter, the AC power consumption meter, the AC power consumption display, the frequency regulation credits display, the processor, the memory, and the communication device,

wherein the AC frequency meter measures a current AC frequency on the AC power line;

wherein the AC power consumption meter measures a current power consumption on the AC power line over a period of time equal to a first sampling interval;

wherein the processor is configured to calculate a power consumption moving average of a last N power current power consumptions measured by the AC power consumption meter such that N is a positive integer greater than 1;

wherein the processor is configured to generate credits or debits based on the current power consumption, the current AC frequency and the power consumption moving average;

wherein the processor is configured to add the credits or debits to a frequency regulation credit and store the credits, debits, or credits and debits on the memory device;

for each next sampling interval of multiple sampling intervals, the power and frequency regulation meter is configured to repeat measuring the current AC frequency, measuring the current power consumption, calculating the power consumption moving average, generating the credit or debit, adding the credits or debits to the frequency regulation credit, and storing the frequency regulation credit or debit on the memory device;

wherein a credit is generated when the current power consumption when compared to the power consumption moving average is driving the current AC frequency of the AC power line toward a nominal AC frequency of the AC power line;

wherein a debit is generated when the current power consumption when compared to the power consumption moving average is driving the current AC frequency of the AC power line away from the nominal AC frequency of the AC power line;

wherein the generation of the credit or debit includes;

generation of a debit in response to a first condition in which the current AC frequency is greater than or equal to an upper threshold frequency and the current power consumption is less than the power consumption moving average, wherein the first condition drives the current AC frequency of the AC power line away from the nominal AC frequency of the AC power line;

generation of a credit in response to a second condition in which the current AC frequency is greater than or equal to the upper threshold frequency and the current power consumption is greater than the power consumption moving average, wherein the second condition drives the current AC frequency of the AC power line toward the nominal AC frequency of the AC power line;

generation of a debit in response to a third condition in which the current AC frequency is less than or equal to a lower threshold frequency and the current power consumption is greater than the power consumption moving average, wherein the third condition drives the current AC frequency of thew AC power line away from the nominal AC frequency of the AC power line;

generation of a credit in response to a fourth condition in which the current AC frequency is less than or equal to the lower threshold frequency and the current power consumption is less than the power consumption moving average, wherein the fourth condition drives the current AC frequency of the AC power line toward the nominal AC frequency of the AC power line;

wherein a credit or a debit is not generated when the current AC frequency is between the upper threshold frequency and the lower threshold frequency;

wherein the power consumption is dynamically and simultaneously displayed via the AC power consumption display and the frequency regulation credit is dynamically and simultaneously displayed via the frequency regulation credits display;

wherein the displayed frequency regulation credit is a cumulative net credit or debit;

wherein the first sampling interval and the multiple sampling intervals collectively includes a time T1 at which the fourth condition prevails with a first credit being generated, a time T2 at which the third condition prevails with a first debit being generated, a time T3 at which the second condition prevails with a second credit being generated, and a time T4 at which the first condition prevails with a second debit being generated, subject to T1<

T2<

T3<

T4;

wherein after the time T2 at which the first debit is generated and before the time T3, the current AC frequency of the AC power line engages in a first movement toward the nominal AC frequency of the AC power line;

wherein the communication device is configured to transmit a frequency regulation credit from the power and frequency regulation meter to the AC power supplier.

2. The power and frequency regulation meter of claim 1,

wherein the processor is configured to initialize a power consumption moving average of N consecutive power consumption measurements, each power consumption measurement made over a respective period of time equal to said sampling interval;

wherein the processor is configured to periodically transfer the frequency regulation credit to a power company supplying AC power on the AC power line.

4. The power and frequency regulation meter of claim 1,

wherein the processor is configured to calculate the frequency regulation credit by using the algorithm:

FRC=SFΣ

[(P−

M)(MF)]

where;

FRC is the frequency regulation credit;

P is the power consumed in a sampling interval;
