TL;DR: In this article, a system for managing loads and detecting outages over electric power lines that comprises wireless temperature sensors which are attached to bare conductors of the electric power line(s), at line junctions or lines' splitting points, for sensing temperatures generated by the currents flow in the conductors.
Abstract: A system for managing loads and detecting outages over electric power lines that comprises wireless temperature sensors which are attached to bare conductors of the electric power line(s), at line junctions or lines' splitting points, for sensing temperatures generated by the currents flow in the conductors. The system also includes a Current Measurement Units (CMU) for wirelessly reading the temperature sensed by the sensors, to allow cheap, rapid and easy RMS currents measurements on power lines at any voltage levels, by using temperature into current conversion formulas and tables.

TL;DR: In this paper, the optimal operation of a neighborhood of smart households in terms of minimizing the total energy procurement cost is analyzed and a simple strategy in order to promote the fair usage of distribution transformer capacity is proposed.
Abstract: In this paper, the optimal operation of a neighborhood of smart households in terms of minimizing the total energy procurement cost is analyzed. Each household may comprise several assets such as electric vehicles, controllable appliances, energy storage and distributed generation. Bi-directional power flow is considered both at household and neighborhood level. Apart from the distributed generation unit, technological options such as vehicle-to-home and vehicle-to-grid are available to provide energy to cover self-consumption needs and to inject excessive energy back to the grid, respectively. The energy transactions are priced based on the net-metering principles considering a dynamic pricing tariff scheme. Furthermore, in order to prevent power peaks that could be harmful for the transformer, a limit is imposed to the total power that may be drawn by the households. Finally, in order to resolve potential competitive behavior, especially during relatively low price periods, a simple strategy in order to promote the fair usage of distribution transformer capacity is proposed.

TL;DR: In this article, a first shielding box is disposed so that its first surface can be opposite to an electric power feeding unit, and the remaining five surfaces thereof reflect the resonant electromagnetic field (near field) generated in the surroundings of the electric power receiving unit.
Abstract: A first shielding box is disposed so that its first surface can be opposite to an electric power feeding unit. The first surface has an opening and remaining five surfaces thereof reflect, during reception of electric power from the electric power feeding unit, a resonant electromagnetic field (near field) generated in the surroundings of the electric power receiving unit. The electric power receiving unit is provided in the first shielding box to receive the electric power from the electric power feeding unit via the opening (first surface) of the first shielding box. A second shielding box has a similar configuration, i.e., has a second surface with an opening and remaining five surfaces thereof reflect the resonant electromagnetic field (near field) generated in the surroundings of the electric power feeding unit.
