1. A method for supplying power to a load using multiple power sources, comprising:
- providing power comprising a first value of a parameter from a first power source to the load;
monitoring the first value;
providing power comprising a second value of the parameter from a second power source to the load, wherein the second value comprises substantially the first value when the first value is within a range of values for the parameter and is within the range when the first value is outside the range;
disconnecting the first power source from the load when the first value is not within the range; and
reconnecting the first power source to the load when the first value is within the range and while the second power source continues to provide power to the load.

Abstract
The present invention provides systems and methods that allow for individual power sources to be disconnected and reconnected without interrupting the power supply from the other power sources and that allow for these power sources to provide power at substantially the same electrical parameters such as frequency, phase, and voltage.

19. A method of supplying power to a load using a plurality of generators, comprising:
-
connecting the plurality of generators to the load;
providing a synchronization frequency from a controller which is external to the plurality of generators;
providing power from each of the plurality of generators to the load wherein the power provided by each of the generators comprises a frequency which is substantially the synchronization frequency. - View Dependent Claims (20, 21)

22. A power generating system, comprising:
-
a generator including an inverter capable of producing an output waveform having a frequency to power a load; and
a controller connected to the generator wherein the controller is capable of providing the frequency for producing the output waveform and is operative to drift the frequency to substantially match a frequency from a second power source.

23. A power distribution system, comprising:
-
a load;
a grid power source connected to the load which provides power having a grid frequency;
a generator connected to the load which provides power having a generator frequency;
a controller connected to the generator wherein the controller is operative to provide the generator frequency to the generator and is operative to drift the generator frequency to the grid frequency; and
a sensor connected to the grid power source and to the controller that measures a grid operating condition. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)

31. A method for detecting whether a potential power source is still providing power to a load, comprising:
-
providing power having a first frequency from a first power source to the load;
providing power having a second frequency from a second power source to the load wherein the second frequency is substantially the same as the first frequency;
attempting to drift the second frequency of the power from the second power source away from the first frequency of the power from the first power source;
monitoring the second frequency of the power provided by the second power source; and
evaluating whether the first power source is providing power to the load. - View Dependent Claims (32, 33, 34, 35, 36)
