Method and apparatus for tertiary control of microgrids with integrated over-current protection
A method and apparatus for tertiary control with over-current protection. In one embodiment, the method comprises calculating at least one unconstrained optimal net intertie target for an area of a power network; calculating, for each resource within the area, optimal scheduled current to achieve the at least one unconstrained optimal net intertie target; calculating, using the optimal scheduled currents and a plurality of stress coefficients, net scheduled current for each power line segment within the area; comparing the net scheduled currents to corresponding stress thresholds to identify any stress violations; reducing, when the comparing step identifies one or more stress violations, the optimal scheduled current for one or more resources contributing to the one or more stress violations; and calculating, when the comparing step identifies the one or more stress violations, updated optimal scheduled current for one or more resources not contributing to the one or more stress violations.

SYSTEM AND METHOD FOR MICROGRID CONTROL
A software-defined control (SDC)-enabled microgrid system includes a physical plane having multiple distributed energy resources (DERs), the DERs being operatively coupled together via a bus, and a control plane. The control plane includes at least one virtual controller running on a hardware server in the control plane, a system analysis module in communication with the physical plane, and an SDC manager coupled with the virtual controller and the system analysis module. The virtual controller includes multiple software-defined functional modules configured to control prescribed parameters of the microgrid.

System and method of managing power for recharging electric vehicles
A method of managing power for recharging electric vehicles efficiently stores, delivers, and distributes energy. The method includes a plurality of user accounts managed by at least one remote server. The system includes a plurality of mobile computerized recharging stations, wherein each mobile computerized recharging station tracks a location and a current amount of available power within a power storage system. The method begins by prompting each user account to search for at least one best-match station. A search request is relayed for the best-match station from a corresponding user PC device to the remote server. The current location is compared to the station location for each mobile computerized recharging station. The minimum threshold of available power is compared to the current amount of available power for each proximal station. The sufficiently-powered station is displayed as the best-match station through the user PC device.
