Google patents grid software that adjusts power plans based on forecast errors

This patent describes a method for managing electricity grids by choosing how far ahead to plan based on how accurate the energy forecasts are. The system runs an optimization process to decide which power sources to use, then automatically adjusts the plan for the next time period once the current one ends.

Why it mattersIt offers a specific way to make power grids more stable by tailoring planning horizons to the reliability of weather or demand predictions.

In the filing’s own words

Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for operating sources of electricity in an electrical grid having a forecasting error rate are described. In some implementations, a method includes selecting a forecast horizon based on the forecasting error rate; performing an optimization process for dispatch planning of the electrical grid for the selected forecast horizon; automatically operating one or more power sources of the electrical grid in accordance with the dispatch planning for a first time increment; and performing an optimization process for dispatch planning for subsequent time increments within the selected horizon after the first time increment has elapsed.

What exactly they claim (claim 1)

1. A method of operating an electrical grid, the method comprising: selecting a forecast horizon based on a forecasting error rate of the electric grid; performing an optimization process for dispatch planning of the electrical grid for the selected forecasting horizon; automatically operating one or more power sources of the electrical grid in accordance with the dispatch planning for a first time increment; and performing an optimization process for dispatch planning for subsequent time increments within the selected horizon after the first time increment has elapsed.
