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.

Abstract: A method for monitoring an electric power source changeover switch, including a step of identifying all of the combinations of operating modes and availability states of the power sources, a step of associating a configuration of a state of switches with each combination, a step of watching for a change in configuration. Upon a change in configuration, a step of controlling the switches is executed in order to place the switches in a state complying with the configuration. In the absence of a change in configuration, a step monitors the compliance of the configuration with the actual state of the switches. A method further including monitoring a source changeover switch implemented in a test device, and to a source changeover switch implementing such a method.

Abstract: An alternating current (AC) power distribution system may include an independent speed variable frequency (ISVF) generator configured to generate an AC power signal having a frequency that is independent from a frequency of a prime mover. The system may also include at least one AC load configured to receive the AC power signal without performing a full-distribution-power-rated power conversion. In another embodiment, an AC power distribution system includes a generator configured to generate an AC power signal and an AC motor configured to receive the AC power signal without performing a full-distribution-power-rated power conversion, where the AC motor is configured to rotate at a rotational frequency that is independent from a frequency of the AC power signal.
