Abstract: A power converter includes a power conversion circuit having a first terminal set and a second terminal set, configured to convert power input via one of the first terminal set and the second terminal set and output the converted power via the other of the first terminal set and the second terminal set; a measurement unit; a controller configured to control the power conversion circuit to generate a voltage/current waveform travelling along the first network with a power supplied by a second power source linked to the second terminal set of the power conversion circuit in response to a condition that a change rate of the measurement of the voltage/current exceeds a threshold; and locate a fault on the first network. The power conversion circuit can be re-used for different modes of operation either for power transmission under normal condition or for fault location under fault condition.

Abstract: Embodiments of present disclosure relate to an apparatus and a method for controlling a delta-connected cascaded multilevel converter. The apparatus (100) for controlling a delta-connected cascaded multilevel converter (110) comprises: a converter controller (102) configured to: receive current signals indicating phase currents flowing through respective phase arms of the converter (110); determine a harmonic current signal indicating a circulating current of the converter (110) from the current signals; and generate, based on the determined harmonic current signal and a reference current signal, a harmonic voltage signal to cause an amplitude of the circulating current flowing through the phase arms of the converter (110) to be a predetermined amplitude.

Abstract: A control system and photovoltaic system and micro-grid using the same and method thereof. The control system for controlling a photovoltaic converter includes: a first input, for receiving first signals indicating first sampling values of an input current of the photovoltaic converter provided by a solar panel; a second input, for receiving second signals indicating second sampling values of an input voltage of the photovoltaic converter provided by the solar panel; a third input, for receiving third signals indicating third sampling values of an output voltage of the photovoltaic converter; and a controller, for first regulating the output voltage of the photovoltaic converter in a direction towards a reference voltage based on the third sampling value by regulating the input voltage by first voltage change of a first predetermined level; wherein: the controller is further adapted for monitoring a trend of the input voltage and power provided by the solar panel based on the first sampling values and the second sampling values for the previous sampling time points and the current sampling time point, and suspending the first regulation in case that the trend changes. This allows for an improvement of transient response of the control system and preventing possible overshooting of a lower input voltage even when the solar panel operating point is relatively far away from the MPP.

Abstract: Embodiments of the present disclosure relate to a method and system for determining a reference power for an energy storage system (ESS) in a wind power generation system. In an embodiment of the present disclosure, the method comprises filtering an actual wind power output to obtain a desired power output delivered to a grid; determining a reference output power for the energy storage system from the actual wind power output and the desired power output delivered to the grid; and adjusting the reference output power for the energy storage system based on a change in predicted wind power output at the next time point. With embodiments of the present disclosure, it can provide a direct control strategy for smoothing wind farm output fluctuations and limiting power ramping rate within required range, which is more practically feasible than the existing strategies and could result in better control performance.
