  • Methods and apparatus for power generation and distribution
    Patent number: 11418054
    Abstract: Methods and apparatus according to various aspects of the present invention may operate in conjunction with a microgrid capable of connecting to a main electrical grid supplying electrical power at a frequency (or other characteristic, such as voltage). A sensor may provide a signal to a control system, wherein the signal corresponds to the frequency (or other characteristic) of the electrical power from the main electrical grid. The control system may compare the frequency (or other characteristic) of the electrical power from the main electrical grid to a first threshold, and automatically provide power from the microgrid to the main electrical grid if the frequency (or other characteristic) of the electrical power from the main electrical grid crosses the first threshold.
    Type: Grant

  • Methods and apparatus for power generation and distribution
    Patent number: 10935945
    Abstract: Methods and apparatus for power generation and distribution according to various aspects of the present invention may operate in conjunction with a control system for controlling electrical power flowing between a main electrical grid providing main electrical grid power having a frequency, a supplemental power system, and a load. The control system may operate in conjunction with a switch system, wherein the switch system selectively connects the supplemental power system to the main electrical grid. A controller may be responsive to the main electrical grid power frequency and control the switch system. The controller may compare the main electrical grid power frequency to a first threshold and autonomously cause the switch system to connect the supplemental power system to the main electrical grid in response to the frequency of the main electrical grid power crossing the first threshold.
