Abstract: An attachment for a hair styling apparatus, the attachment comprising an annular duct having an air inlet for receiving an airflow from a hair styling apparatus, and at least one vane located within the duct for directing the airflow from the air inlet towards an air outlet.

Abstract: A method for coordinated control of a renewable electrical energy source (RES) and an electrical energy storage (EES) device utilizes a time-dependent forecast of electrical energy production by the RES and a state of charge (SOC) schedule for the EES including at least one SOC target value. A time-varying charge/discharge control signal is configured to ensure that the SOC schedule is satisfied by charging at a rate necessary to meet the SOC target value, while periodically updating the generation of the charge/discharge control signal based upon an updated time-dependent forecast of electrical energy production and/or an updated SOC schedule. A configurable refresh period may be used to limit updates of the time-varying control signal including computation and use of a new basepoint value for aggregated energy supplied from the RES?ESS facility to an electrical grid.

Abstract: The present disclosure provides a method for controlling a solar power plant comprising a plurality of solar modules. The method may comprise (a) obtaining irradiance data at a first time and a second time from a plurality of sensors disposed among or adjacent to the plurality of solar modules; (b) processing the irradiance data at the first time and the second time to generate an output that indicates whether one or more solar modules of the plurality of solar modules will be covered by a shadow or shade at a third time; (c) generating, based at least in part on the output, a power output prediction for the plurality of solar modules at the third time; and (d) adjusting a power output of the solar power plant based at least in part on the power output prediction.

Abstract: Methods for controlling an integrated renewable energy source (RES) and energy storage system (ESS) of a RES-ESS facility having a point of grid interconnect (POGI) limit are provided. A forecast for energy production of the RES as well as a state of charge (SOC) schedule are used to calculate a SOC target-based POGI cap that is less than the POGI limit, with the SOC target-based POGI cap representing as low a peak power output value as possible while still ensuring satisfaction of the SOC schedule. The forecasted RES production, SOC schedule, and SOC target-based POGI cap are used to generate a time-varying charge/discharge control signal for the ESS that ensures the SOC schedule is satisfied.
