1. A method of controlling operation of a microgrid using an energy management system (EMS), the microgrid comprising a plurality of distributed energy resources including at least one controllable distributed hydrocarbon fueled generator and electrical energy storage devices, the method comprising:
the EMS measuring a cumulative availability status of each distributed energy resource, and assigning a state of the microgrid based upon said cumulative availability status;
determining whether a critical operation can proceed based upon said state; and
enabling the critical operation based upon the determining step having a predetermined outcome.
