  • Patent number: 10954918
    Abstract: A solution to optimally manage those requirements ensuring on the one hand, that the requirements set by the grid operators are appropriately and accurately accomplished at a point of interconnection (POI) and on the other hand, preventing the wind turbines from over fulfilling the requirements, for example, by remaining connected at voltages levels higher or lower than the ones required which, although possible, may cause higher loads and currents in the wind turbines than needed to fulfill the requirements.

  • Patent number: 10947957
    Abstract: An apparatus, system and method for generating electricity using stored kinetic energy of a flywheel. The apparatus has a generating mechanism, an air passageway, a heating chamber and a heating mechanism. A wind turbine rotates a drive shaft and a pair of flywheels that are independently and selectively rotated by the drive shaft. Input air flowing in the passageway rotates the wind turbine. While one flywheel rotates with the drive shaft to build up kinetic energy, the other flywheel rotates free of the drive shaft to use kinetic energy to drive an output shaft and generate electricity. A heat exchanger heats air in the heating chamber to produce convective air flow to draw input air through the passageway. A thermal energy storage tank stores heat for the heat exchanger. The system includes a source of electricity to power a pump. The method uses the apparatus to produce electricity.
