Asset Fuel-Reserve Based Microgrid Control Strategy

A method for sustained reliability of a microgrid power system comprising:

• inputting historical load and weather date of the microgrid power system to a forecasting block;
• determining, at the forecasting block, forecasted site load and weather factors for the microgrid power system;
• inputting the forecasted site load and weather factors to a microgrid controller block;
• inputting fuel efficiency curves and asset fuel levels for power assets of the microgrid power system to the microgrid controller block;
• inputting real-time fuel costs for the power assets to the microgrid controller block;
• determining, at the microgrid controller block, an asset dispatch schedule for longest microgrid sustenance for the power assets of the microgrid power system based on the forecasted site load and weather factors, the fuel efficiency curves and the asset fuel levels, and the real-time fuel costs;
• determining, at real-time asset dispatch block, asset dispatch commands based on the asset dispatch schedule and an actual site load;
• and
• outputting the asset dispatch commands to the power assets of the microgrid power system.

A microgrid power system comprising:

• a microgrid load requiring power from the microgrid system;
• a plurality of power assets of different power asset types providing power to the microgrid power system;
• an electronic network connecting the microgrid load and the plurality of power assets for transferring power and for communicating monitoring and control information;
• and
• a microgrid controller operatively connected to the microgrid load, the plurality of power assets and the electronic network, the microgrid controller configured to:
• receive historical load and weather date of the microgrid power system,
• determine forecasted site load and weather factors for the microgrid power system,
• receive fuel efficiency curves and asset fuel levels for the plurality of power assets,
• determine an asset dispatch schedule for the power assets of the microgrid power system based on the forecasted site load and weather factors,
• determine a refueling timeline for the plurality of power assets based on the forecasted site load and weather factors, the fuel efficiency curves and the asset fuel levels,
• output the refueling timeline to a monitor of the microgrid power system,
• determine asset dispatch commands based on the asset dispatch schedule and an actual site load, and
• output the asset dispatch commands to the power assets of the microgrid power system.
