Abstract
Systems and methods described herein can involve reducing a feeder system model by node cell segmentation on feeder system according to system topology information and system operation characteristics to generate a node cell segmented distribution grid; constructing observational data from systemwide status information aggregated from nodes identified from the node cell segmented distribution grid to meet a reinforcement learning (RL) policy network input requirement; training an RL policy framework to generate control actions for controllable components of the system; and executing the RL policy framework to generate control actions for controllable nodes in the node cell segmented distribution grid.
