Abstract: Technologies are generally described for addressing the bidirectional power flow conflict incurred by power surpluses produced from a number of households' on-location energy generation units (e.g., solar) in power distribution networks. A micro grid composed of households in a neighborhood may be considered as a generating- or consuming-resource entity at different time periods. The approach may be formulated as a power balance computation such that power balance may not be achieved within the micro grid itself, and therefore power sharing (or redispatching) among micro grids is operated, before requesting power from the macro grid, i.e., the fuel-based conventional grid. Enhancement of renewable energy utilization and reduction in the amount of data packet traffic in exchange of information and control messages via uplink and downlink transmissions throughout an overlay multi-tier communications network infrastructure may be taken into consideration in example implementations.

Abstract: A wireless power transmission device includes a main body, a first transmitter coil and a second transmitter coil. The second transmitter coil is stacked over the first transmitter coil. If the wireless power transmission device is operated in a detecting mode, a magnetic flux is generated by the first transmitter coil and oriented in the direction toward the top surface of the main body. The magnetic flux is attenuated by the overlying second transmitter coil. Consequently, the electromagnetic wave is inhibited. If the wireless power transmission device is operated in a charging mode, both the first transmitter coil and the second transmitter coil are controlled to transmit magnetic fluxes. Since the intensity of the electric power is increased, the charging efficiency is enhanced.

Abstract: A wireless power transmission device includes a main body, a first transmitter coil and a second transmitter coil. The second transmitter coil is partially stacked over the first transmitter coil.

Abstract: Technologies are generally described for alleviating solar power congestion in a distribution grid via smart metering communications. According to some examples, a power network system supervised by utility operators may monitor and control grid-tied power generation modules associated with consumers to ensure the distribution grid is stable in terms of network capacity limit. A communications infrastructure including home area networks (HANs) and neighborhood area networks (NANs) between smart meters and utility control centers may facilitate power congestion management. Utility control centers (UCCs) in cooperation with smart meters or energy management units (EMUs) may selectively disconnect consumer power generation units to maintain the system reliability.

Abstract: A wireless heat generation device includes an antenna, a controller, a heating element, and a temperature sensor. The antenna is used for receiving a radio wave and converting the radio wave into electric energy. The controller is used for receiving the electric energy and providing an electric power to the heating element. After the electric power is received by the heating element, the electric power is converted into heat. The temperature sensor is used for sensing a temperature within the wireless heat generation device. If the temperature reaches a preset temperature, the controller stops providing the electric power to the heating element. Consequently, the possibility of causing an overheating problem of the wireless heat generation device will be eliminated.

The first encapsulated transmission coil and the second encapsulated transmission coil are disposed in the main body, and the second encapsulated transmission coil is adjacent to the first encapsulated transmission coil. Each of the first encapsulated transmission coil and the second encapsulated transmission coil has a quadrangular winding configuration so that the magnetic flux generated at the short-side section of the first or second encapsulated transmission coil is greater than the magnetic flux generated by an encapsulated transmission coil having a circular winding configuration. Therefore, the wireless charging range of the wireless transmitting device for wireless charging is improved.
