A method of controlling discharge of a holdup capacitor in a power system having a voltage source, a holdup capacitor and a load. The method including operably connecting the voltage source to the load, monitoring a first voltage of the voltage source, and if the first voltage of the voltage source drops below a selected threshold, directing energy from the holdup capacitor to the load via a first path, and directing energy from the holdup capacitor to the load via a second path if a selected condition is satisfied.

In one embodiment, a power distribution system includes a DC power input for receiving DC power from a renewable energy source, an AC power input for receiving AC power, a multi-phase pulse power output for transmitting multi-phase pulse power, an AC power output for transmitting the AC power, and a controller for allocating power to the multi-phase pulse power output and the AC power output.

The present disclosure relates to a power supply management system adapted for use with at least one utility proxy power source, to help control powering a load when an AC mains power source is not available to provide power to the load. The system has a power converter forming an uninterruptible power supply, and includes a controller configured to control operation of the power converter. A supplemental battery subsystem is included which is in communication with the power converter for supplying DC power to the power converter. The controller monitors the application of power from the utility proxy to the load and uses the DC power supplied by the supplemental battery subsystem, when needed, to supplement the generation of power by the power converter, to thus assist the power converter in powering the load along with the power being provided by the utility proxy.

A system and method for combining a remote audio source with an animatronically controlled puppet includes the steps of entering an audio file on a user client by a person where the audio file is a statement spoken by the person. The audio file is sent to a secondary client that is remote to the user client. The secondary client has a puppet controlled by animatronics. The audio file is received by an audio circuit board that converts the audio file into movement parameters. The movement parameters are sent to at least one servomechanism mounted in the puppet to actuate the animatronics in synchronicity with the audio file. Movement of the puppet is video recorded to define a video file. The audio and video files are combined to define a final video production viewable by the person.

Embodiments related to a power platform having a mobile trailer, a tower pivotally attached to the mobile trailer, and a plurality of power sources. The plurality of power sources including at least a solar panel disposed on the tower and a fuel cell generator. The power platform also includes a housing having a transfer switching assembly and a power cord panel, wherein the transfer switching assembly is configured to receive electrical power generated from the plurality of power sources and convert the electrical power for transfer to ancillary devices via the power cord panel.

The invention relates to a device, system and method for balancing power in an electrical power grid, to which a plurality of households are connected. The total electrical power production of those households that have a net electrical power production is calculated, as well as the total electrical power consumption of those households that have a net electrical power consumption. The ratio of the values obtained is then calculated, and compared to a predetermined value. Depending on the outcome of the comparison, a signal is created that triggers the switching of an apparatus in one of the households to an on-state or an off-state. In this way, an effective balancing of the supply with the consumption of electricity in a local low-voltage power grid has been achieved.

Systems and methods regarding distributed energy resource systems (DERs) are described. Configurations and employed methods may include sending a command to a DER system to place the DER system in one or more of a charge state, a discharge state, an idle state, or a reactive power state. These DER systems may include an energy storage circuit, a dc/ac converter configured to receive a DC voltage from the storage circuit and convert the received DC voltage for receipt by an external AC circuit, and one or more controllers configured to designate operation state of the storage circuit in at least a charge state, a discharge state, and an idle state.

The present device and method provide continuous power supply to consumers at a minimal cost. The present device combines electrical power from a plurality of direct and alternating current sources while working together with or separately from an external electrical power grid. Inside of the device, generation sources are connected via DC/DC and AC/DC converters to a DC bus, to which batteries are also connected via a charge control system. DC current is converted into AC current through reversible AC/DC converters according to the number of grid phases and an AC bus is connected to said converters, allowing for energy from an external grid to also be used for charging the batteries. The method of control is based on a cyclical program for selecting energy sources, said program being executed by a control unit and having dynamic parameter correction that takes into account present and projected energy production and consumption.

An energy storage system for a building includes a battery and an energy storage controller. The battery is configured to store electrical energy purchased from a utility and to discharge stored electrical energy for use in satisfying a building energy load. The energy storage controller is configured to generate a cost function including a peak load contribution (PLC) term. The PLC term represents a cost based on electrical energy purchased from the utility during coincidental peak hours in an optimization period. The controller is configured to modify the cost function by applying a peak hours mask to the PLC term. The peak hours mask identifies one or more hours in the optimization period as projected peak hours and causes the energy storage controller to disregard the electrical energy purchased from the utility during any hours not identified as projected peak hours when calculating a value for the PLC term.
