摘要： Aspects and embodiments described herein are directed toward a power interface device including a first power interface configured to couple to an electric utility and a second power interface configured to couple to a microgrid comprising one or more power sources and one or more loads, the one or more power sources including a generator. The power interface device also includes a power conversion circuit coupled to the first power interface and the second power interface and a controller coupled to the power conversion circuit. The controller is configured to allow interfacing between the electric utility operating at a first frequency and voltage and the microgrid operating at a second frequency and voltage by at least detecting an operating frequency of the generator and controlling a power flow between the electric utility and the microgrid based on the operating frequency of the generator.

摘要： A distributed energy resource (DER) may store electrical power from an AC circuit and discharge stored electrical power to the AC circuit. A DER may be coupled to the AC circuit via a plug inserted into a receptacle coupled to the AC circuit, and a load device may be plugged into the DER via a receptacle of the DER. The DER may pass AC power from the AC circuit to the load device, and may draw additional power from the AC circuit to charge an energy storage circuit of the DER. The DER may also discharge stored energy into the AC circuit and/or power the load device directly.

摘要： A system for generating a duty cycle control signal for controlling an inverter power train providing an output current waveform to a grid operating with a grid voltage waveform compares a reference current waveform shaped to the grid voltage waveform with the output current waveform to generate an error signal. The error signal is used to generate a corrective control action signal, which is combined with a feed-forward signal representing a nominal duty cycle generated with a feed-forward function. The combination of the feed-forward signal and the corrective control action signal provide the duty cycle control signal.

摘要： Electrical malfunctions in a network which are caused by torque fluctuations of an electric motor, in particular flicker, are reduced by using a control device. For simple and cost-effective minimizing or even correction of such malfunctions with the control device, the control device has at least one first input for supplying an input signal which contains information suitable for determining the loading of the network by torque fluctuations and at least one output for transmitting an output signal to at least one converter supplying the electric motor. This makes it possible to reduce or ideally to eliminate electrical malfunctions in a network which are caused by torque fluctuation of the electric motor.

摘要： In order to provide a method for regulating a reactive power compensator, which is connected to an alternating current line having multiple phases, wherein for each phase an actual voltage V12, V23 and V31 present thereon is detected and from the actual voltages V12, V23 and V31 a counter system actual fraction is calculated. A control circuit suppresses the counter system actual fraction. A feedback loop determines the level of suppression of the counter system actual fraction with the help of controlled parameters. The method enables an adjustment of the counter system that is largely independent from operating staff. Accordingly, a comparator unit compares the counter system actual fraction to the counter system target fraction and defines the controlled parameters as a function of the comparison.
