Method for determining relative value of electrical loads
The patent US11979023B2 outlines a method and apparatus for determining the relative value of electrical loads that can be controlled via a user interface. The core of the invention involves a controller that learns the relative value of these loads intuitively based on user interactions, specifically ON/OFF commands. When a user activates a load, the controller interprets this as an indication that the load's value is too low, while deactivating a load suggests its value is too high. The system operates by establishing a primary solution of operating states for a group of loads, ensuring that the net weight of activated loads meets a primary threshold. The controller then infers a secondary solution for a subset of loads, allowing it to dynamically update the relative values of the loads based on changes in their operating states.
The patent further details the calculations involved in updating the values of the loads, including specific formulas for determining updated values based on the changes in operating states. It also describes iterative processes for refining these values over time to converge on a true value for each load. Additionally, the controller is designed to re-normalize load values to a fixed total, enhancing the accuracy of the value assessments. The claims encompass both the method and the apparatus, including a non-transitory computer-readable medium that executes the described processes, thereby providing a comprehensive framework for managing electrical loads based on user feedback.
