  • Patent number: 11509138
    Abstract: A power electronic control-based capacitor to be used at the terminal of a grid-connected wind generator system for improving the transient stability of the generator following a fault in the network. This eliminates the need of adding auxiliary control devices at the grid side. The wind generator terminal capacitor is controlled through power electronics in such a way as to function both at the steady state and transient conditions maintaining the stability of the wind generator. A power electronic control-based terminal capacitor (ā€œCā€) is connected through two back-to-back thyristor switching devices, T1 and T2. The function of the capacitor depends on the triggering or firing-angle of the thyristor switches, which varies from 0 degrees to 180 degrees.

  • Patent number: 11309701
    Abstract: Flexible AC transmission system (FACTS) enabling distributed controls is a requirement for power transmission and distribution, to improve line balancing and distribution efficiency. These FACTS devices are electronic circuits that vary in the type of services they provide. All FACTS devices have internal circuitry to handle fault currents. Most of these circuits are unique in design for each manufacturer, which make these FACTS devices non-modular, non-interchangeable, expensive and heavy. One of the most versatile FACTS device is the static synchronous series compensator (SSSC), which is used to inject impedance into the transmission lines to change the power flow characteristics. The addition of integrated fault current handling circuitry makes the SSSC and similar FACTS devices unwieldy, heavy, and not a viable solution for distributed control. What is disclosed are modifications to FACTS devices that move the fault current protection external to the FACTS device and make them modular and re-usable.

  • Patent number: 11268496
    Abstract: Various embodiments distributively control a wind park having a plurality of wind turbines. Each wind turbine controlled by its own turbine controller. Each turbine controller determines power production capability of its dedicated wind turbine. The power production capability of the single wind turbine is communicated with a plurality of other turbine controllers in the wind park. A consensus power distribution schedule to distribute power to a power grid is determined using votes from each turbine controller in the wind park. Energy is discharged from each wind turbine to a power grid according to the power distribution schedule. When one wind turbine fails, a new power distribution schedule is determined using votes from each remaining turbine controller and energy is discharged from each wind turbine to the power grid according to the new power distribution schedule.
