1. A method for a utility grid having a network of interconnecting segments of power lines connecting generating units to consuming units, each of said interconnecting segments-having a maximum electric power capacity, said method comprising:

  • computing a probable electric power output for each of a plurality of generating units, each of said plurality of generating units having a maximum electric power generating capacity, said plurality of generating units including at least one generating unit whose electric power output depends on the weather, and a respective confidence level associated with each of said plurality of generating units, for a given time interval;

    computing a probable electrical power load for each of a plurality of consuming units, each of said plurality of consuming units having a maximum allowed electric power load, and a respective confidence level associated with each of said plurality of consuming units, for said time interval; and

    determining whether there are paths having one or more segments of power lines from each of said generating units to each of said consuming units, said paths satisfying the following constraints;

    a) the actual output of each of said generating units is less than or equal to the probable output thereof for said time interval;

    b) the actual load of each of said consuming units is less than or equal to the probable load thereof for said time interval; and

    c) the actual load capacity for each of said segments is less than or equal to the maximum load capacity thereof for said time interval; and

    when there are paths satisfying said constraints;

    setting the utility grid to said paths; and

    transmitting electric power over said paths for said time interval.
