Innovation Solution
Implementing a decentralized control and automation solutions by dividing the power grid into zones, each with a zonal controller, and a federated grid management system, and a federated grid management system, with zonal autonomous control and federated data fabric for data fidelity and consistent modeling across distribution and transmission systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If centralized control is used to manage power grids, then control coordination is simplified, but the system cannot handle the increased complexity and number of node points effectively
Solution Approach 1:
The patent divides the power grid into multiple zones, each with its own autonomous controller that manages local node points and circuit configurations. This segmentation allows the complex power grid to be handled through distributed regional control rather than overwhelming centralized control, resolving the contradiction between grid complexity and control capability.
2Adaptability or versatility
If the number of controllable node points increases, then power grid flexibility and control options improve, but monitoring and management complexity increases
Solution Approach 1:
By segmenting the power grid into zones with autonomous controllers, the patent distributes the monitoring and management burden across multiple independent units. Each zonal controller handles its local node points independently, maintaining control flexibility while preventing overall system complexity from becoming unmanageable.
Solution Approach 2:
The autonomous zonal controllers perform self-monitoring and self-management of their respective zones, reducing the need for centralized monitoring of every node point. This self-service capability allows the system to handle increased numbers of controllable points without proportionally increasing overall management complexity.
3Ease of operation
If decentralized zonal control is implemented, then management of complex node points improves, but system coordination complexity increases
Solution Approach 1:
The patent introduces a federated grid management system that acts as an intermediary layer between individual zonal controllers and the overall power grid. This intermediary coordinates actions across zones, enabling effective node point management through decentralized control while preventing coordination complexity from becoming unmanageable through the mediating federated system.

AI summary
Provided herein is a power grid system comprising an advanced distribution management system (ADMS) and a distribution zonal measurement device configured to measure zonal distribution operational parameters for an assigned distribution zone of a plurality of distribution zones. Each of the plurality of distribution zones has an associated distribution zonal measurement device and a distribution zonal controller in communication with the distribution zonal measurement device and the ADMS. In some aspects, the distribution zonal controller is configured to receive distribution zonal operational data for the assigned distribution zone from the distribution zonal measurement device and determine a distribution zonal orchestration index based on the distribution zonal operational data. The distribution zonal controller is further configured to communicate the distribution zonal orchestration index to the ADMS and determine an adaptive control action for one or more distribution control devices in the assigned distribution zone based on the distribution zonal orchestration index.
