Masterless distributed power transfer control
First Claim
1. A method of power transfer control among a plurality of power sources coupled through a distribution system, each of the power sources having a controller, the method comprising:
- determining, at the controller of each of the plurality of power sources, an assignment of priorities for each of the plurality of power sources, wherein the priorities establish a hierarchy of the power sources for supplying power to a load;
obtaining, at the controller of each power source, information indicating an availability of each of the plurality of power sources and determining a set of available power sources from among the plurality of power sources based on the information;
identifying, at the controller of each power source, a preferred power source and a standby power source from the plurality of power sources based on the priorities and the information, wherein the preferred power source and the standby power source are among the set of available power sources, and wherein the priority of the preferred power source is higher than the priority of the standby power source;
determining, at the controller of each power source, to change the preferred power source from a first power source to a second power source in response to detecting a condition; and
conducting, at the controller of the first power source and the second power source, a power transfer between the first power source and the second power source in response to determining to change the preferred power source to the second power source.

Abstract
A method of power transfer control among a plurality of power sources coupled through a distribution system. The method comprises determining, at each power source of the plurality of power sources, an assignment of priorities for each of the plurality of power sources. The method also comprises obtaining, at each power source, information indicating an availability of each of the plurality of power sources and determining a set of available power sources, and identifying, at each power source, a preferred power source and a standby power source from the plurality of power sources. The method further comprises determining to change the preferred power source from a first power source to a second power source in response to detecting a condition, and conducting the power transfer.

13. An apparatus, comprising:
a circuitry configured to; determine an assignment of priorities for each of a plurality of power sources coupled through a distribution system, wherein the priorities establish a hierarchy of the power sources for supplying power to a load; obtain information indicating an availability of each of the plurality of power sources and determine a set of available power sources from among the plurality of power sources based on the information; identify a preferred power source and a standby power source from the plurality of power sources based on the priorities and the information, wherein the preferred power source and the standby power source are among the set of available power sources, and wherein the priority of the preferred power source is higher than the priority of the standby power source; determine to change the preferred power source from a first power source to a second power source in response to detecting a condition; determine whether the apparatus is either of the first power source or the second power source; and conduct a power transfer between the first power source and the second power source in response to both determining to change the preferred power source to the second power source and determining the apparatus is either the first power source or on the second power source. - View Dependent Claims (14, 15, 16, 17, 18)

19. A generator set, comprising:
-
an engine; a generator driven by the engine to generate electrical power; and a controller communicably coupled to the engine and configured to; determine an assignment of priorities for each of a plurality power sources coupled through a distribution system, the plurality of power sources comprising the generator set, wherein the priorities establish a hierarchy of the power sources for supplying power to a load; obtain information indicating an availability of each of the plurality of power sources and determining a set of available power sources from among the plurality of power sources based on the information; identify a preferred power source and a standby power source from the plurality of power sources based on the priorities and the information, wherein the preferred power source and the standby power source are among the set of available power sources, and wherein the priority of the preferred power source is higher than the priority of the standby power source; determine to change the preferred power source from a first power source to a second power source in response to detecting a condition; determine if the generator set is either of the first power source or the second power source; and conduct a power transfer between the first power source and the second power source in response to both determining to change the preferred power source to the second power source and determining the generator set is the first power source or the second power source. - View Dependent Claims (20, 21, 22, 23, 24)
