  • Publication number: 20250253665
    Abstract: An energy storage system and an operating method thereof are provided. The energy storage system provides power regulation for the power grid. The energy storage system includes an energy storage unit, a measurement unit and a control unit. The measurement unit measures the operating frequency of the power grid. When the operating frequency is between the third frequency and the third frequency boundary value, the control unit configures the regulation ratio of the power regulation to be less than or equal to the second output boundary value and greater than or equal to the second operating ratio. The third frequency boundary value is less than the first frequency boundary value. The second operating ratio is greater than the first operating ratio, and the efficiency of supplying power at the second operating ratio is greater than that at the first operating ratio by an efficiency threshold.

The energy storage system includes an energy storage unit, a measurement unit and a control unit. The measurement unit measures the operating frequency of the power grid. When the operating frequency is between the third frequency boundary value and the fourth frequency, the control unit configures the regulation ratio of the power regulation to be less than or equal to the second operating ratio and greater than or equal to the second input boundary value. The second operating ratio is less than the first operating ratio, and the efficiency of charging the energy storage unit by the power grid at the second operating ratio is greater than that at the first operating ratio by an efficiency threshold.

  • Publication number: 20250253696
    Abstract: An energy storage system and an operating method thereof are provided. The energy storage system provides power regulation for the power grid. The energy storage system includes an energy storage unit, a measurement unit and a control unit. The measurement unit measures the operating frequency of the power grid. The control unit configures the energy storage system to provide the power regulation in a first power regulation mode during a first period according to at least one of an operation target, the operating frequency of the power grid, and the state of charge of the energy storage unit. The control unit compares an operation effect with the operation target and configures the energy storage system to provide the power regulation in a second power regulation mode during a second period. The operation target includes at least one of a contracted regulation power amount and a contracted regulation time.

    Abstract: An energy storage system and an operating method thereof are provided. The energy storage system provides power regulation for the power grid. The energy storage system includes an energy storage unit, a measurement unit and a control unit. The measurement unit measures the operating frequency of the power grid, and the control unit receives the operating frequency measured by the measurement unit. When the operating frequency is greater than or equal to a first frequency boundary value and less than or equal to a second frequency boundary value, the control unit configures the regulation ratio of the power regulation to be a first operating ratio which is less than or equal to 0 and greater than or equal to the first input boundary value. The first frequency boundary value is less than the first frequency, and/or the second frequency boundary value is greater than the second frequency.

  • Patent number: 10049509
    Abstract: The present invention provides a system and method for transmitting apparatus-related information in real time. The system comprises at least one server in signal communication with at least one external apparatus in a wired or wireless way. While an abnormality of an external apparatus occurs, the external apparatus transmits a set of abnormality information to the server. After an information receiving interface of the server receives the set of abnormality information transmitted by the external apparatus, an information processing module vocally broadcasts the set of abnormality information. An information transmitting module transmits the set of abnormality information to the client device of at least one assigned related person. While an external apparatus suffers abnormality, the system can inform the related persons in real time to repair the external apparatus instantly.
