  • Patent number: 12136820
    Abstract: An exemplary power system includes a DC power bus and a photovoltaic system connected to the DC power bus. An energy storage system is connected to the DC power bus and stores energy injected to the DC power bus by the photovoltaic system. A power inverter is connected to the DC power bus and converts power between the DC power bus and an AC connected load. The power system also includes a control system that receives power system data from one or more sub-systems and devices connected to the DC power bus, and controls, in real-time, one or more of the power inverter and the energy storage system to act as a load on the DC power bus based on the received power system data.

  • Publication number: 20240297500
    Abstract: A power oscillation damping controller includes a control block including one or more circuits configured to receive a meter input and transmit a controller output. The meter input includes an active power sub-controller measured value including an evident oscillation component of a power oscillation, a reactive power sub-controller measured value including an alternative oscillation component of the power oscillation, or a combination thereof. The controller output includes an active power component adjustment based on the active power sub-controller measured value that configures or results in an evident dampening of the power oscillation, a reactive power component adjustment based on the reactive power sub-controller measured value that configures or results in an alternative dampening of the power oscillation, or a combination thereof.

  • Publication number: 20240204335
    Abstract: A battery thermal event management system includes an enclosure to store a plurality of battery modules, one or more ventilation panels, at least one actuator to open the one or more ventilation panels, and at least one sensor to detect one or more parameters. Further, the battery thermal event management system includes a detection system with a processor memory, and programming in the memory, coupled to the enclosure. The programming causes the battery thermal event management system to detect, via the at least one sensor, the one or more parameters. Next, the battery thermal event management system determines whether the detected one or more parameters indicate a ventilating event. Further, based on the detected one or more parameters indicating the ventilating event, the battery thermal event management system opens, via the at least one actuator, the one or more ventilation panels.
