A load control system may include control devices capable of being associated with each other at one or more locations for performing load control. Control devices may include control-source devices and/or control-target devices. A location beacon may be discovered and a unique identifier in the location beacon may be associated with a unique identifier of one or more control devices. Upon subsequent discovery of the location beacon, the associated load control devices may be controlled. The beacons may be communicated via radio frequency signals, visible light communication, and/or audio signals. The visible light communication may be used to communicate other types of information to devices in the load control system. The visible light communication may be used to identify link addresses for communicating with load control devices, load control instructions, load control configuration instructions, network communication information, and/or the like. The information in the beacons may be used to commission and/or control the load control system.

Systems for power distribution within a power source unit are well suited for use in power source units that work with power distribution networks such as may be found associated with wireless communication systems or the like. More specifically, exemplary aspects provide a flexible power cable that extends from a powering supply to printed circuit boards (PCBs) on which output power ports are located. The PCBs may be arranged in a cascaded or daisy chain topology or in a star topology relative to the powering supply.

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.

A distribution system may include at least one Power Management System (PMS) that controls electrical power distributed transmitted by the distribution system. The system may include a first power station located at an onshore platform. The first power station may include an onshore terminal that distributes electric power to the first power station and to at least one onshore load. The first power station may include various onshore reactors that monitor inbound reactive power received from the onshore terminal or that monitor outbound reactive power sent to a remote location. The system may include a second power station located at an offshore platform which is located at the remote location. The second power station may include an offshore terminal that receives electric power from the first power station and that delivers electric power to at least one offshore load.

The measurement of solar irradiance measurement have important applications, including solar resource assessment, solar power plants, photovoltaic system monitoring, heating and cooling loads of buildings, climate modeling and weather forecasting. An option to establish this is to solely measure the global horizontal irradiance and employ an irradiance decomposition algorithm to derive direct normal irradiance and diffuse horizontal irradiance. However, these models vary in complexity and generally have a relatively high uncertainty particularly between latitudes +60° N and −45° S these errors which includes large portions of North America, Europe, Russia, and Asia where the applications are centered. The inventors have established an improved methodology based upon an improved decomposition algorithm yielding improved accuracy in derived solar irradiance measurements in conjunction with a low cost non-moving part spectral pyranometer supporting spectral global irradiance measurements and spectral clearness indices.
