Scalable hierarchical energy distribution grid utilizing homogeneous control logic

Abstract

Techniques are disclosed for implementing a scalable hierarchical energy distribution grid utilizing homogeneous control logic are disclosed that provide distributed, autonomous control of a multitude of sites in an energy system using abstraction and aggregation techniques. A hierarchical energy distribution grid utilizing homogeneous control logic is provided that includes multiple control modules arranged in a hierarchy. Each control module can implement a same energy optimization scheme logic to directly control site energy resources and possibly energy resources of sites associated with control modules existing below it in the hierarchy. Each control module can act autonomously through use a similar set of input values to the common optimization scheme logic.

What is claimed is: 
     
         1 . A distributed electrical grid system, comprising:
 a plurality of interconnected nodes, wherein each of the plurality of interconnected nodes includes:
 an aggregate net load profile including all local loads and immediate child loads; 
 an aggregate energy generation (EG) resource including all local EG resources and immediate child EG resources; and 
 an aggregate storage capacity including a local storage capacity and immediate child storage capacities, 
   wherein each of the plurality of interconnected nodes is configured to normalize its aggregate net load profile by using its aggregate EG resource and aggregate storage capacity.   
     
     
         2 . The distributed electrical grid system of  claim 1 , wherein the aggregate net load profile also includes immediate parent loads. 
     
     
         3 . The distributed electrical grid system of  claim 2 , wherein the aggregate EG resource also includes immediate parent EG resources. 
     
     
         4 . The distributed electrical grid system of  claim 3 , wherein the aggregate storage capacity also includes immediate parent storage capacities. 
     
     
         5 . The distributed electrical grid system of  claim 1 , wherein each node of the plurality of interconnected nodes is configured to implement a same energy optimization scheme logic as each of the other nodes of the plurality of interconnected nodes. 
     
     
         6 . The distributed electrical grid system of  claim 1 , wherein each node of the plurality of interconnected nodes is kept independent by making it unaware of changes to the plurality of interconnected nodes located more than one level upstream or downstream of the node. 
     
     
         7 . The distributed electrical grid system of  claim 1 , wherein each node of the plurality of interconnected nodes is a control module configured for energy optimization. 
     
     
         8 . The distributed electrical grid system of  claim 1 , wherein each node of the plurality of interconnected nodes maintains awareness of its aggregate EG resource, aggregate net load profile and aggregate storage capacity by way of messages being exchanged between nodes located one level upstream and/or downstream of the node. 
     
     
         9 . The distributed electrical grid system of  claim 1 , wherein the plurality of interconnected nodes are arranged in at least three different levels. 
     
     
         10 . The distributed electrical grid system of  claim 1 , wherein a node of the plurality of interconnected nodes not serving as a parent to any other node is configured to utilize a total energy generation (EG) value of a site of the node as a first input, a total load value of the site as a second input and a total storage capacity of the site as a third input.
