  • Controlling virtual microgrids in a power network
    Patent number: 11888319
    Abstract: Implementations are directed to achieving a real-time and distributed control solution that can at least selectively achieve a deterministic flow of power at a virtual point of interconnection (vPOI) of a virtual microgrid, where there is limited or no power measurement data available at the vPOI. Some of those implementations are directed to automatically generating virtual microgrids for a power network, optionally including generating additional and/or alternative virtual microgrids in response to transient and/or persistent changes to the power network. Some of those implementations are additionally or alternatively directed to dynamic control of a virtual microgrid to achieve the deterministic flow of power at the vPOI thereof.

  • Safety constraints for a control algorithm based drug delivery system
    Patent number: 11883632
    Abstract: Disclosed are a system, methods and computer-readable medium products that provide safety constraints for an insulin-delivery management program. Various examples provide safety constraints for a control algorithm-based drug delivery system that provides automatic delivery of a drug based on sensor input. Glucose measurement values may be received at regular time intervals from a sensor. A processor may predict future glucose values based on prior glucose measurement values. The safety constraints assist in safe operation of the drug delivery system during various operational scenarios. In some examples, predicted future glucose values may be used to implement safety constraints that mitigate under-delivery or over-delivery of the drug while not overly burdening the user of the drug delivery system and without sacrificing performance of the drug delivery system. Other safety constraints are also disclosed.
