Distributed optimization for hybrid ac-dc microgrid

A microgrid system includes a plurality of energy resource systems, including direct current (DC) energy resource systems and alternating current (AC) energy resource systems, configured to supply power to a microgrid; a plurality of local controllers respectively associated with an energy resource system for controlling the respective energy resource system; and a microgrid controller. Each local controller is configured to determine an available output power for a respective energy resource system based on one or more operational constraints, and transmit an indication of the available output power to the microgrid controller. The microgrid controller is configured to determine, based on the available output power indicated by each local controller, a net available DC output power available from the DC energy resource systems and a net available AC output power available from the AC energy resource systems.
