Micro-Inverter Based AC-Coupled Photovoltaic Microgrid System with Wireless Smart-Grid Controls

A microgrid system comprising:

• an alternating current (AC) bus;
• a plurality of distributed energy resources (DERs) connected to the AC bus;
• at least one load connected to the AC bus;
• and
• a microgrid controller configured to:
• determine loss of power from an electrical grid to the microgrid,
• determine, in response to the loss of power from the electrical grid, an amount of energy generated by the plurality of DERs,
• determine, an amount of energy required to support the at least one load, and
• alter, based on the determined amount of energy produced by the plurality of DERs and the amount of energy required to support the at least one load, status of one of:
• at least one of the plurality of DERs and the at least one load.

A system for managing distributed energy resources, the system comprising:

• a memory;
• and
• a processor coupled to the memory, the processor configured to:
• determine an amount of energy generated by each of a plurality of distributed energy resources (DERs) connected to a microgrid;
• determine an amount of energy required to power each of a plurality of loads connected to the microgrid;
• and
• alter, based on the determined amount of energy generated by the each of the plurality of distributed energy resources and the amount of energy required to power each of the plurality of loads connected to the microgrid, a status of at least one of the plurality of loads connected to the microgrid.
