Method and System for Efficient Energy Distribution in Electrical Grids Using Sensor and Actuator Networks
First Claim
1. In a distributed commodity resource-based network wherein a first node in the network distributes an amount of the commodity to two or more other nodes in the network, a method of managing distribution of the commodity, the method comprising the steps of:
- the first node obtaining two or more marginal demand functions, respectively, from the two or more other nodes, wherein a marginal demand function represents a price for a given amount of the commodity that a given node is willing to pay;
the first node aggregating the two or more marginal demand functions respectively obtained from the two or more other nodes to form an aggregated marginal demand function; and
the first node determining an optimal allocation of aggregate amounts of the commodity to the two or more other nodes based on the aggregated marginal demand function.

Abstract
Techniques are disclosed for managing a commodity resource in a distributed network by aggregating marginal demand functions or marginal supply functions, depending on whether a node is a commodity consumer or a commodity producer, and determining an optimal allocation/production based on the aggregated function. By way of example, the commodity being managed may be an energy-based commodity such as electrical energy. In such case, the distributed commodity resource-based network may be a distributed electrical grid network.

10. In a distributed commodity resource-based network wherein a first node in the network receives an amount of the commodity from two or more other nodes in the network, a method of managing production of the commodity, the method comprising the steps of:
-
the first node obtaining two or more marginal supply functions, respectively, from the two or more other nodes, wherein a marginal supply function represents a given amount of the commodity that a given node is willing to supply; the first node aggregating the two or more marginal supply functions respectively obtained from the two or more other nodes to form an aggregated marginal supply function; and the first node determining an optimal production of aggregate amounts of the commodity from the two or more other nodes based on the aggregated marginal supply function.

11. A device that at least one of consumes and produces a commodity in a distributed commodity resource-based network, the device comprising:
-
a processor; a sensor coupled to the processor for monitoring at least one of consumption and production of the commodity; an actuator coupled to the processor for controlling at least one of consumption and production of the commodity; and an interface coupled to the processor for allowing the processor to communicate with the network; wherein the processor generates one or more marginal utility functions that represent at least one of;
(i) a price for a given amount of the commodity that the device is willing to pay when operating as a consumer of the commodity; and
(ii) a given amount of the commodity that the device is willing to supply when operating as a producer of the commodity;further wherein the processor sends the one or more marginal utility functions to a controller in the network for aggregating multiple marginal utility functions respectively obtained from multiple devices in the network and for determining at least one of an optimal allocation and production of the commodity.
