Abstract

A method and apparatus for optimizing the cost of scheduling maintenance of a distributed energy generator. In one embodiment, the method comprises obtaining information, from a controller, related to impaired operation of at least one component in a distributed energy generator, wherein the distributed energy generator comprises a plurality of components; calculating a cost to restore non-impaired operation of the distributed energy generator; calculating a cost of lost power due to the impaired operation of the distributed energy generator; and determining an optimal time to schedule maintenance of the distributed energy generator based on the calculated cost to restore non-impaired operation and the calculated cost of lost power.
