摘要： Systems and methods for managing reactive power during low voltage ride through are provided. Responsive to detecting a fault on a power grid, a controller may identify a power regulation mode of the generator system. The controller can switch the power regulation mode to an offset power regulation mode of the generator system responsive to identifying the power regulation mode. The controller may adjust a value of a parameter of the generator system from a normal value to an offset value, wherein the parameter is selected based on the offset power regulation mode. The controller can maintain the value of the parameter as the offset value for a period of time. After the period of time, the controller can modify the value of the parameter from the offset value to the normal value, and the power regulation mode from the offset power regulation mode to the identified power regulation mode.

摘要： A charging system includes a power input part, an inverter, a DC bus, at least one charging device, a first bidirectional energy storage module, a second bidirectional energy storage module and an intelligent controller. The charging device includes a DC/DC converter and a charging gun. A first bidirectional DC/DC converter of the first bidirectional energy storage module receives and converts the DC power from the inverter for charging a first battery, or converts a first storage electric energy of the first battery for the charging device. A second bidirectional DC/DC converter of the second bidirectional energy storage module receives and converts the electric energy outputted by the DC/DC converter of the charging device for charging a second battery, or converts a second storage electric energy of the second battery for the charging device. The intelligent controller controls operations of the first bidirectional DC/DC converter and the second bidirectional DC/DC converter.

摘要： A power and energy management (PEM) method for managing power consumed by a plurality of power devices on a network. The method includes: a monitoring step (S1) to determine whether PEM is required based on the power available on the network and the power consumption of the power devices on the network; a monitor step (S2) to determine the operating status of each of the power devices on the network; a step (S4) of determining a strategy for operating the power devices in response to a determination in the monitoring step that PEM is required; a step (S5) of determining a coordination strategy for recharging of any storage devices on the network in response to a determination in the first network monitoring step that PEM is not required; and controlling (S6) devices on the network to operate at a power consumption level and/or to recharge based on the above steps.

摘要： Anomaly detection, classification, and prediction is provided. A system can include one or more processors coupled with memory. The system can identify voltage waveform data corresponding to electricity distributed over a utility grid and measured by a metering device. The system can detect, based on a comparison with baseline voltage waveform data, an anomaly in at least a portion of the voltage waveform data. The system can generate spectrogram data for the at least the portion of the voltage waveform data comprising the anomaly. The system can determine, via a model trained with machine learning, a type of the anomaly based on the spectrogram data. The system can provide an indication of the type of the anomaly to cause an action to be performed on the utility grid responsive to determination of the type of anomaly.

摘要： A power supply system includes at least one group of power supply modules. The power supply module includes a first string, a first residual current detection circuit, an inverter circuit, and a first controller. The first residual current detection circuit is connected between the first string and an input end of the inverter circuit, and an output end of the inverter circuit is connected to an alternating current power grid. When a first residual current value detected by the first residual current detection circuit is greater than a first preset residual current threshold, the first controller controls the first string to be disconnected from the inverter circuit, or controls the inverter circuit to be disconnected from the alternating current power grid.

摘要： This application provides a power supply system and a conversion method. The power supply system includes a power generation apparatus, a converter circuit, and a drive control circuit. The drive control circuit may be configured to: when a power grid fails, control, based on duration of previous low voltage ride-through, the converter circuit to increase a value of a current to be output to the power grid from a first operating current value to a low voltage ride-through current value, to increase a voltage value at an output end of the converter circuit. Herein, the previous low voltage ride-through is latest low voltage ride-through. In this application, the system can control, based on duration of previous voltage ride-through, a current to be output by the converter circuit to the power grid, to reduce circuit oscillation, with a simple structure, a simple control method, and high safety.
