Autonomous control system for power distribution grid management
The patent US12068602B2 describes a sophisticated control system designed for power distribution grids. Central to this system is a processor and memory that work together to construct a grid model, which includes nodes and edges representing various assets and transmission paths. The system is capable of generating an analysis of the grid's operation over a specified future time period, simulating power transmission under anticipated load growth. It identifies potential constraint violations—deviations from operational constraints—along with their predicted occurrence times. The system then generates multiple alterations to address these violations, selects the most effective alteration, and autonomously implements it to optimize grid performance.
Further functionalities of the control system include the ability to switch equipment between different grid portions and activate renewable energy sources or demand response mechanisms through communication protocols like the Open Field Message Bus. The system evaluates potential alterations based on various criteria, including implementation time, cost, reliability, and environmental impact. It also allows for collaborative analysis between different agent nodes within the grid, enhancing the decision-making process. The method outlined in the patent emphasizes a proactive approach to grid management, ensuring that multiple constraint violations can be resolved efficiently and effectively, thereby improving the overall resilience and reliability of power distribution systems.
