Abstract
A method for controlling a power distribution system having a number of nodes and controllable grid assets associated with at least some of the node includes acquiring observations via measurement signals associated with respective nodes and generating a graph representation of a system state based on the observations and topological information of the power distribution system. The topological information is used to determine edges defining connections between nodes. The observations are used to determine nodal features of respective nodes, which are indicative of a measured electrical quantity and a status of controllable grid assets associated with the respective node. The graph representation is processed using a reinforcement learned control policy to output a control action for effecting a change of status of one or more of the controllable grid assets, to regulate voltage and reactive power flow in the power distribution system based on a volt-var optimization objective.
