Abstract: An assembly compensates for reactive power and active power in a high-voltage network. The assembly has a first converter, which is configured for the compensation of active power, and a second converter, which is connected in series and which is configured to compensate reactive power. The voltage that is provided or can be output by the assembly corresponds to the sum of the voltages of the first converter and of the second converter.

Abstract: Power is provided from an energy storage device to a utility network based on a detected condition, such as a fault, in the network. Specifically, it is determined whether a fault on the utility network is a near fault or a far fault relative to the energy storage device. Whether a fault is classified as “near” or “far” is determined based on a voltage drop in the utility network. Power is then supplied to the utility network based on whether the fault is a near fault or a far fault.

Abstract: Voltage of a utility grid is reliably and swiftly restored, which decreased due to a utility grid failure or the like, to reference voltage. A generator is connected to a utility grid. A voltage detecting section detects voltage of a utility grid. A control section determines reactive current corresponding to the voltage obtained from the voltage detecting section based on voltage current correlation information in which the voltage of the utility grid and the reactive current to be supplied to the utility grid are correlated with each other. An electric power converting section regulates the reactive current to be supplied to or absorbed from the utility grid. An information changing section changes the voltage current correlation information to increase an amount of the reactive current with respect to a variation in the voltage in the voltage current correlation information, in the case where the voltage of the utility grid is not in a predetermined range set in advance after a predetermined time period has passed since the voltage of the utility grid varied by a predetermined amount.
