Abstract

A method and system determines a location of a conversion device for converting wind energy into electrical energy by considering both technical and economic viability factors. One or more qualified wind data regions are established within a geographic area. Each qualified wind data region meets or exceeds a wind velocity criteria over a requisite time period. Distribution accessible zones are established where a desired range of electrical energy is distributable via existing distribution infrastructure. Candidate regions are determined based on the overlap of the regions and the zones. Land data is obtained and is associated with the candidate region. The land data may comprise at least one of a land use and a holder of an interest in real property associated with the candidate region. A selector selects a preferential region, for placement of a conversion device, from the candidate regions based on a land data.

Claims

1. A method for determining a location of a conversion device for converting wind energy into electrical energy, the method comprising:

establishing one or more qualified wind data regions within a geographic area, the qualified wind data regions meeting or exceeding a wind velocity criteria over a requisite time period;

establishing accessible distribution zones where a desired range of electrical energy is distributable via existing distribution infrastructure;

determining candidate regions based on the overlap of the regions and the zones;

obtaining land data associated with the candidate region including at least one of a land-use data and holder data, the holder data comprising information associated with a holder of an interest in real property associated with the candidate region; and

selecting a preferential region, for placement of an energy conversion device, from the candidate regions based on the land data.

2. The method according to claim 1 wherein the land data comprises land-use data indicative of at least one of vacant land, agricultural land, and land generally free of ground clutter.

3. The method according to claim 1 wherein the land data comprises holder data associated with a holder of a real property interest in the preferential region, the holder data including at least one of a credit report, a credit analysis, financial data, and a historical annual income of the holder.

4. The method according to claim 1 further comprising:

obtaining financial data associated with the holder; and

selecting a preferential region, for placement of a conversion device, from the candidate regions based on a land use indicative of vacant or agricultural land and the financial data associated with the holder compliant with a financial criteria.

5. The method according to claim 1 wherein the distribution infrastructure represents at least one of a transmission line, a power station, a substation, a monopoles, and a tower, and location data associated with any of the foregoing items.

6. The method according to claim 1 wherein the wind velocity criteria comprises an average of approximately six meters per second in at least one direction over the requisite time period of at least three months.

7. The method according to claim 1 wherein the establishing of the accessible distribution zones comprises establishing the accessible distribution zone within a maximum linear distance from the existing distribution infrastructure.

8. The method according to claim 5 wherein the maximum linear distance is ten kilometers.

9. The method according to claim 1 wherein the energy conversion device comprises at least one wind turbine and wherein desired range of electrical energy is within a range from approximately 200 kilowatt-hours to approximately 20 megawatt-hours to reduce the complexity or requirement for a substation.

10. The method according to claim 1 wherein a potential interconnection point to the distribution infrastructure is associated with a transmission line having a rating of less than or equal to approximately 69 kilovolts.

11. The method according to claim 1 wherein a potential interconnection point of the distribution infrastructure is less than ten kilometers from the preferential region and wherein the potential interconnection point is associated with a transmission line with a rating between 15 kilovolts and 25 kilovolts.

12. A system for determining a location of a conversion device for converting wind energy into electrical energy, the system comprising:

a wind data module for establishing one or more qualified wind data regions within a geographic area, the qualified wind data regions meeting or exceeding a wind velocity criteria over a requisite time period;

an accessible distribution model for establishing accessible distribution zones where a desired range of electrical energy is distributable via existing distribution infrastructure;

a candidate determination module for determining candidate regions based on the overlap of the regions and the zones;

a land data manager for obtaining land data associated with the candidate region including at least one of a land-use data and holder data, the holder data comprising information associated with a holder of an interest in real property associated with the candidate region; and

a selector for selecting a preferential region, for placement of an energy conversion device, from the candidate regions based on the land data.

13. The system according to claim 12 wherein the land data comprises land-use data indicative of at least one of vacant land, agricultural land, and land generally free of ground clutter.

14. The system according to claim 12 wherein the land data comprises holder data associated with a holder of a real property interest in the preferential region, the holder data including at least one of a credit report, a credit analysis, financial data, and a historical annual income of the holder.

15. The system according to claim 12 where the selector selects a preferential region, for placement of a conversion device, from the candidate regions based on a land use indicative of vacant or agricultural land and the financial data associated with the holder compliant with a financial criteria.

16. The system according to claim 12 wherein the distribution infrastructure represents at least one of a transmission line, a power station, a substation, a monopoles, and a tower, and location data associated with any of the foregoing items.

17. The system according to claim 12 wherein the wind velocity criteria comprises an average of approximately six meters per second in at least one direction over the requisite time period of at least three months.

18. The system according to claim 12 wherein the accessible distribution zone is established within a maximum linear distance from the existing distribution infrastructure.

19. The system according to claim 18 wherein the maximum linear distance is ten kilometers.

20. The system according to claim 12 wherein the energy conversion device comprises a wind turbine and the desired range of electrical energy is within a range from approximately 200 kilowatt-hours to approximately 20 megawatt-hours to reduce the complexity or requirement for a substation.

21. The system according to claim 12 wherein a potential interconnection point to the distribution infrastructure is associated with a transmission line having a rating of less than or equal to approximately 69 kilovolts.

22. The system according to claim 12 wherein a potential interconnection point of the distribution infrastructure is less than ten kilometers from the preferential region and wherein the potential interconnection point is associated with a transmission line with a rating between 15 kilovolts and 25 kilovolts.
