AN IMPROVED ENERGY MANAGEMENT SYSTEM AND MICROGRID

A method of controlling operation of a microgrid using an EMS, the microgrid comprising a plurality of distributed energy resources including at least one controllable distributed hydrocarbon fuelled 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 status; determining whether a critical operation can proceed based upon said state; enabling the critical operation based upon the determining step having a pre-determined outcome.
