Claim 0:
1. A method of controlling a microgrid including a plurality of controllable assets, the method comprising:
retrieving, by an energy management system, EMS, a forecast variable value for at least one forecast variable;
executing, by the EMS, an optimization routine to determine an operating point vector for the plurality of controllable assets that is optimal for the retrieved forecast variable value, the operating point vector including an operating point value for each of the plurality of controllable assets;
executing, by the EMS, the optimization routine to determine several additional operating point vectors for the plurality of controllable assets, the additional operating point vectors being determined to be optimal for modified forecast variable values that deviate from the retrieved forecast variable value;
providing both the operating point vector and the several additional operating point vectors to a power management system, PMS, of the microgrid;
selecting, by the PMS, one of the operating point vectors; and
controlling the plurality of controllable assets based on the selected operating point vector.
