A smart radio frequency identification (RFID) system for controlling operation of electrical units is disclosed. The system includes a RFID tag, a control unit coupled to the RFID tag, a relay unit connected to the control unit and to the electrical unit, and an external RFID reader for generating radio frequency (RF) signals for sending data to the RFID tag when the RFID reader is placed next to the RFID tag. The RFID tag checks and stores the data and passes the data along to the control unit. The control unit sends a control signal to the relay unit in accordance with instructions contained in the data, causing the relay unit to operate the electrical unit between a first state and a second state. The system may also include sensors to monitor certain conditions of the electrical unit and cause the control unit to turn off the electrical unit when the conditions are abnormal.

A power management apparatus includes a receiver configured to receive measurement information obtained by measuring a power of a facility connected to a power grid; and a transmitter configured to transmit a power control message. The transmitter transmits the power control message based on an output power amount of a distributed power supply provided in the facility, in addition to the measurement information. The measurement information is information indicating a total power flow amount from the power grid to the facility or a total reverse power flow amount from the facility to the power grid. The distributed power supply is a power supply that allows a reverse power flow from the facility to the power grid.

Each of the local agent servers is connected to a respective one of the energy nodes and has a processor configured to: receive input variables or parameters; predict, using the received input variables or parameters, a non-zero energy generation amount that power generation equipment can generate over a planning horizon and an energy consumption amount that will be consumed over the planning horizon; solve, using the energy generation amount and the energy consumption amount, an optimization problem over the planning horizon; and communicate a solution to the optimization problem to the central allocation server. Each of the energy nodes includes power generation equipment, power transmission equipment, and power storage equipment.

Aspects of the subject disclosure may include, for example, a transmission system having a coupling device, a bypass circuit, a memory and a processor. The coupling device can facilitate transmission or reception of electromagnetic waves that propagate along a surface of a transmission medium. The memory can store instructions, which when executed by the processor, causes the processor to perform operations including restarting a timer to prevent the bypass circuit from disabling the transmission or reception of electromagnetic waves by the coupling device. Other embodiments are disclosed.

In a particular illustrative embodiment of the present invention, an inter-island power transmission system is disclosed. An electronic box is placed on each end of a medium voltage three phase power cable running between two islands. The electronic box senses an open cable on the three phase cable and switches to direct current power transmission on the remaining two good cables. The direct current power is converted back to three phase power transmission on the receiving end of the direct current power.

A power distribution control system for controlling a plurality of power assets connected to a power grid is provided. The system includes a server which can identify a set of power assets selected from sources, loads, and stores that are to form a string and provide to the string instructions for response to a change in the power grid. The system further includes a router for each of the power assets in the string, for receiving instructions from the server and for controlling the respective power asset. The power assets in the string are selected by the server to have different response times and/or response profiles, such that the string of assets present a collective response to the change, the collective response being defined by the server.

The present disclosure provides a computer-implemented method for prioritizing one or more instructional control strategies to reduce time-variant energy demand of a built environment associated with renewable energy sources. The computer-implemented method includes collection of a first set of statistical data, fetching of a second set of statistical data, accumulation of a third set of statistical data, reception of a fourth set of statistical data and gathering of fifth set of statistical data. Further, the computer-implemented method includes parsing and comparison of the first set of statistical data, the second set of statistical data, the third set of statistical data, the fourth set of statistical data and the fifth set of statistical data. In addition, the computer-implemented method includes identification and prioritization of one or more instructional control strategies to reduce the time-variant energy demand associated with the built environment.

A communicator communicates with a plurality of management targets. An operation-mode determiner determines, based on information representing a status of each of the management targets each received by the communicator, whether a total system status of the plurality of management targets satisfies a predefined condition. A mode-of-network-communication switch, a communication-parameter changer, a condition-for-device-communication setter, a cycle-for-obtaining-status-value setter and a communication-parameter setter adjust, when the operation-mode determiner determines that the system status satisfies the predefined condition, a communication status of the communicator in accordance with the system status and a processing performance of the device.

Apparatuses and methods for configuring and managing solar panels to form strings of photovoltaic energy generators with improved performance and reduced cost. The photovoltaic energy generators are connected via one or more combined local management units (CLMUs), each having a plurality of direct current converters connected to and configured to receive direct current power from a respective solar panel. A controller unit shared by the CLMU's direct current converters is utilized to separately control the operation of each converter such that the power extracted from the solar panels is maximized. A communications unit coupled with the controller unit is utilized to facilitate communications between the controller unit and a system unit remote from the CLMU to report measurements and receive control signals.
