A method and system of optimizing microgrid operations is provided. One or more intelligent microgrid coordinators interface with the microgrid such that those microgrid coordinators are able to measure and control all microgrid asset activities. The microgrid coordinator is used to forecast the microgrid's demanded load more accurately, and assign asset commands so as to optimize microgrid consumption, generation, and storage of load. The method and system incorporate a valuation of dispatchable load in optimization functions. The microgrid coordinator is further used to protect the microgrid assets from over-current situations when the microgrid is connected to the bulk electric system and when islanded. The method and system provide a means to test the microgrid controller prior to implementation on the microgrid in order to assure proper operation.

In the past, in electrical power networks, the effects on the system of particular contingencies, such as a given power line being interrupted, have been modelled off-line, so that the proper response to that contingency can be planned ahead of time and acted upon quickly in the event of such contingency. Such models have generally been overly conservative adding considerable cost to power systems. The present invention provides a method of predicting the transfer limit or the amount of remedial action required to maintain stability of a power system in the event of a study contingency by determining a transient energy margin, comprising the steps of:
