Abstract

A method for administering an intermittent source of electrical power generation, such as a wind powered electric power generating facility, to produce electric power at a level up to a pre-set level during a selected time period.

Claims

1. A method for administering an intermittent source of electrical power generation such as a wind powered electric power generation facility, for inclusion in a regional electric power transmission and distribution grid to provide up-to-date estimates, or schedules, of the electric power to be produced by the facility during a selected future time period by comparison to at least one past time period, the method comprising:

a) obtaining past electric power production data for the facility for a past time period and for incremental past time portions of the past time period;

b) obtaining an estimate (schedule) of the electric power production for the facility for the selected future time period to provide an electric power production schedule for the facility,

c) reporting the electric power production estimate (schedule) for the selected period to a grid controller;

d) obtaining current electric power production data for the facility for incremental time portions of the selected time period;

e) comparing the current electric power production data from the facility to the past time electric power production data; and

f) adjusting the electric power production estimate (schedule) for the facility for a remainder of the selected period and providing an adjusted electric power production schedule to the grid controller.

2. The method of claim 1 wherein the facility comprises a plurality of intermittently powered electric power generating units.

3. The method of claim 1 wherein the past time period is about one day and wherein the incremental past time portions are about one hour.

4. The method of claim 1 wherein the estimate of the electric power production for the selected future time period is based upon the past electric production data.

5. The method of claim 1 wherein the estimate of the electric power production for the selected past time period is supplied by the operator of the facility.

6. The method of claim 1 wherein the electric power production data comprises actual measured current electric power production from the facility for at least one incremental time period of the selected time period.

7. The method of claim 1 wherein the current electric power production of the facility during an incremental time portion of the selected time period is compared to an incremental past time portion of the past period to determine whether the accuracy of the estimate of electric power production during the selected period is accurate.

8. The method of claim 7 wherein the electric power production schedule to the grid controller is adjusted based upon the comparison.

9. The method of claim 7 wherein an adjusted electric power production schedule based upon the comparison is calculated and provided to the grid controller.

10. The method of claim 9 wherein the adjusted electric power production schedule provided to the grid controller is adjusted to a value at least equal to the electrical power production estimated from the comparison.
