Abstract: Systems, methods, and computer-readable media are described for addressing the unit commitment problem in a power grid by providing a communication-free control framework according to which each power generating unit in the power grid determines its own operating schedule for turning on or off based solely on local measurements.

Abstract: Virtual oscillator control systems, devices, and techniques are provided. One example device includes a processor configured to implement a virtual oscillator circuit and output an oscillating waveform based on the virtual oscillator circuit and power electronics operatively coupled to the processor and configured to convert, based on the oscillating waveform, direct current (DC) electricity to alternating current (AC) electricity. The processor may be further configured to extract, from the virtual oscillator circuit, a virtual current based on an output current of the AC electricity, and output the oscillating waveform further based on an input voltage of the DC electricity.

Abstract: A device includes a control unit that includes an oscillator circuit. The control unit is configured to generate, based on the oscillator circuit, at least one switching signal. The device also includes a direct current (DC)-to-DC conversion circuit comprising at least one electronic switch that is operatively coupled to the control unit. The DC-to-DC conversion circuit is configured to convert, based on the at least one switching signal, a DC input voltage to a DC output voltage, and the control unit is further configured to input, to the oscillator circuit, a current signal that is generated based on a measured output current of the DC-to-DC conversion circuit.

Abstract: Disclosed are systems and methods for improving communication in an optical communication system having spectrally shaped pulses. Embodiments of the systems and methods include sending a first spectrally shaped pulse over a channel connecting a transmitter and a receiver. Then, comparing the spectrally shaped pulse received at the receiver to a predetermined spectrally shaped pulse. The systems and methods further include obtaining a preemphasis coefficient that describes the difference between the spectrally shaped pulse received at the receiver to the predetermined spectrally shaped pulse by utilizing a mathematical description of C(?k)ej(??(?k)) and multiplying a second spectrally shaped pulse with the preemphasis coefficient before sending the second spectrally shaped pulse to the receiver.
