Abstract

One exemplary embodiment is a system including nanogrid controller configured to receive power bids each including a power magnitude value and a bid value from a plurality of resource controllers, evaluate the power bids to determine resource control commands for respective resource controllers and a power bid feedback value, and transmit the resource control commands and a power bid feedback value to the plurality of resource controllers. The plurality of resource controllers are configured to generate and transmit the power bids to the nanogrid controller, receive the resource control command and in response thereto at least one of shed or restore one or more of the power loads and control a supply power from one or more of the power sources, and receive the power bid feedback value and in response thereto generate an updated power bid and transmit the updated power bid to the nanogrid controller.

Claims20

Dependent claims

A system comprising:

a plurality of resources operatively coupled with a nanogrid electrical power distribution network, the plurality of resources including one or more power loads;
a plurality of resource controllers configured to control operation of respective ones of the plurality of resources;
and
a nanogrid controller in operative communication with the plurality of resource controllers;
wherein the nanogrid controller is configured to:
receive power bids from the plurality of resource controllers, the power bids including a power magnitude value and a bid value,
evaluate the power bids to determine resource control commands for respective resource controllers and a power bid feedback value, the resource control commands being configured to control shedding or restoration of one or more of the power loads, the power bid feedback value indicating a value at which the power bids were one of accepted and rejected,
transmit the resource control command to at least one of the plurality of resource controllers, and
transmit the power bid feedback value to the plurality of resource controllers;
wherein the plurality of resource controllers are configured to:
generate and transmit the power bids to the nanogrid controller,
receive the resource control command and in response thereto at least one of shed or restore one or more of the power loads, and
receive the power bid feedback value and in response thereto generate an updated power bid and transmit the updated power bid to the nanogrid controller.

10 more elements

A method of controlling a nanogrid including a plurality of resources including one or more power loads, a plurality of resource controllers configured to control operation of respective ones of the plurality of resources and a nanogrid controller in operative communication with the plurality of resource controllers, the method comprising:

receiving with the nanogrid controller power bids generated by the plurality of resource controllers, the power bids being normalized to a common metric;
evaluating the power bids with the nanogrid controller to determine a resource control command and a power bid feedback value, the resource control command being executable to at least one of control shedding or restoration of one or more of the power loads, the power bid feedback value indicating a value at which the power bids were one of accepted and rejected;
and
outputting the resource control command and the power bid feedback value to a communication network.

1 more element

A apparatus comprising:

a nanogrid controller configured to operatively communicate with a plurality of resource controller coupled with a respective plurality of resources operatively coupled with a nanogrid electrical power distribution network, the plurality of resources including one or more power loads and one or more power sources;
wherein the nanogrid controller is configured to:
receive power bids from the plurality of resource controllers, the power bids including a power magnitude value and a bid value,
evaluate the power bids to determine resource control commands for respective resource controllers and a power bid feedback value, the resource control command being configured to at least one of control shedding or restoration of one or more of the power loads and control supply from one or more of the power sources, the power bid feedback value indicating a value at which the power bids were one of accepted and rejected,
transmit the resource control command to at least one of the plurality of resource controllers, and
transmit the power bid feedback value to the plurality of resource controllers.
