  • Publication number: 20250260235
    Abstract: Microgrid control techniques that combine the benefits of both rule-based and optimizer-based approaches. The techniques are flexible enough to find optimal or near-optimal economic dispatch solutions based on real-time conditions, but that is also deterministic by always reliably calculating a result within a guaranteed timeframe. These techniques provide the optimality of optimizer methods along with the reliability of rule-based methods for microgrid control.

  • Publication number: 20250202235
    Abstract: A microgrid controller microgrid controller of a microgrid system includes processing circuitry configured to calculate real time power demand on the microgrid system; identify candidate energy assets of the microgrid system to activate according to the calculated real time power demand; dispatch candidate energy assets according to lower unit power cost when the candidate energy assets have unit power cost that does not vary with overlapping power distribution among multiple energy assets regardless of whether the unit power cost varies with time; dispatch candidate energy assets according to an a-priori determined optimization of power distribution when the candidate energy assets have unit power cost that varies with overlapping power distribution and does not vary with time; and dispatch candidate energy assets according to real time optimization of power distribution when the candidate energy assets have unit power cost that varies with overlapping power distribution and varies with time.

  • Publication number: 20250125630
    Abstract: A method of operating a microgrid system includes: obtaining a microgrid dispatch schedule input that includes a schedule of required electrical energy generation for the microgrid system for a given time period; filtering the scheduled dispatch input and converting the scheduled dispatch input into power levels to meet power demands for required electrical energy generation of the dispatch schedule input for the microgrid system; receiving a current load level for the microgrid system based on one or more electrical loads electrically coupled to the microgrid system; comparing the schedule of required electrical energy generation to an actual required electrical energy generation for the microgrid system; and dispatching one or more electrical assets in real time to meet a difference between the scheduled required electrical energy generation and the actual required electrical energy generation.

  • Publication number: 20240014670
    Abstract: A self-activating fault protection circuit for an electrical charging system for an on-vehicle rechargeable energy storage device that includes a DC-DC boost converter is described. The self-activating fault protection circuit includes, in one embodiment, an electrical connector including a positive cable and a negative cable, high-voltage electric power bus, and a self-activating fault protection circuit including a high-voltage diode. The DC-DC boost converter is electrically connected to the rechargeable energy storage device via the high-voltage electric power bus, and the electrical connector is electrically connected to the DC-DC boost converter via the positive cable and the negative cable. The high-voltage diode is arranged in the negative cable between the electrical connector and the DC-DC boost converter.
