  • Patent number: 11817700
    Abstract: A decentralized electrical power allocation system is provided. The system includes a power bus, electric power consumers, and at least two power source assemblies. Each power source assembly includes a power controller and a power source. Each power controller is configured to execute an adaptive droop control scheme so as to cause their respective power sources to output power to meet a power demand on the power bus applied by the power consumers. The power output of a given power source is controlled based at least in part on correlating a power feedback of the given power source with a droop function that represents an efficiency of the given power source to generate electrical power for a given power output. The droop functions are collaboratively defined so that one power source shares more output at lower power levels while another power source shares more output at higher power levels.

  • Patent number: 11305665
    Abstract: Some embodiments provide a system to protect an electric vehicle charging infrastructure. An electric vehicle charging site may receive Alternating Current (“AC”) power from a power grid and provides Direct Current (“DC”) power to electric vehicles. A sensor spoof observer and controller may receive information from at least two AC current sensors, wherein the observer calculates a grid voltage disturbance using a structure based on an AC filter dynamic model. A system stability assurance platform may: (i) monitor current and voltage to detect resonance, (ii) identify impedance associated with a detected resonance, and (iii) apply a result of an analysis of the identified impedance to an adaptive damping control algorithm. A user interface platform may then provide information about a component of the charging infrastructure being cyber-attacked to a distribution system operator via a graphical user interface display.
