摘要： A system for controlling a microgrid includes microgrid assets and a tieline for coupling the microgrid to a bulk grid; and a tieline controller coupled to the tieline. At least one of the microgrid assets comprises a different type of asset than another one of the microgrid assets. The tieline controller is configured for providing tieline control signals to adjust active and reactive power in respective microgrid assets in response to commands from the bulk grid operating entity, microgrid system conditions, bulk grid conditions, or combinations thereof.

摘要： A method for controlling operation of a power generation and delivery system while increasing a power output of the power generation and delivery system is described. The method includes, monitoring an output parameter of the power generation and delivery system and determining a rate of change of the output parameter as a function of time. A reactive current command signal is generated a as a function of the determined rate of change of the output parameter. Operation of a power converter is controlled based at least partially on the reactive current command signal to facilitate maintaining a substantially constant terminal voltage as the power output of the power generation and delivery system is increased.

摘要： A torsional mode damping controller system is connected to a converter that drives a drive train including an electrical machine and a non-electrical machine. The controller system includes an input interface configured to receive measured data related to variables of the converter or the drive train and a controller connected to the input interface. The controller is configured to calculate at least one dynamic torque component along a section of a shaft of the drive train based on the measured data from the input interface, generate control data for a rectifier and an inverter of the converter for damping a torsional oscillation in the shaft of the drive train based on the at least one dynamic torque component, and send the control data to the rectifier and to the inverter for modulating an active power exchanged between the converter and the electrical machine.
