1. A system for controlling a microgrid, the system comprising:

  • a plurality of microgrid assets comprising electric generators, heat generators, electric loads, heat loads, thermal storage components, water pumps and water storage components; and

    a dispatch controller coupled to the plurality of microgrid assets and configured for providing control signals to adjust operation of respective microgrid assets in response to a predictive optimization control algorithm, such that heat and power generated together or independently by the plurality of microgrid assets interconnected on electric and/or thermal grids of any specified topology, and further such that water dispatch, are together scheduled to optimize the solution of an objective function associated with microgrid operation over a predetermined time horizon based on predicted future microgrid asset conditions, electric generator up-time and down-time constraints, thermal generator up-time and down-time constraints, and combined heat and power generator up-time and down-time constraints, wherein the dispatch controller is further configured to be responsive to the prediction optimization control algorithm based on load shedding costs that are proportional to the amount of shortfall between the demanded and supplied load.
