1. A computer-implemented method, comprising:
- receiving an opportunity to vary a control on a utility grid comprising a plurality of possible grid control actions;
receiving effectiveness data for the possible grid control actions comprising confidence intervals around the effects of each possible grid control action;
selecting a grid control action, using a processor, based on the overlap in confidence intervals of the effectiveness data; and
implementing the selected grid control action on the utility grid,further comprising determining an opportunity to vary a control on a utility grid by referencing current states of the controls on the utility grid and a multidimensional space representing possible grid control actions.

Abstract
Systems and methods for automatically selecting actions to take on a utility grid to simultaneously reduce uncertainty while selecting actions that improve one or more effectiveness metrics. Grid action effects are represented as confidence intervals, the overlap of which is used as a weight when selecting actions within a constrained search space of grid actions. The response of the utility grid to the grid actions may be measured and parsed by the temporal and spatial reach of the grid action, then used to update the confidence intervals for that particular selected grid action.
