Dynamic voltage restoration (DVR) is a method of overcoming voltage sags and swells that occur in electrical power distribution. Devices used for DVR include static var devices, which are series compensation devices that use voltage source converters (VSC). The DVR is used to inject three phase voltage in series and in synchronism with the network voltages in order to compensate voltage disturbances with a benefit of active /reactive power control.
The capacity factor is the ratio of an actual electrical energy output over a given period of time to the maximum possible electrical energy output over that period. Nuclear power plants are at the high end of the range of capacity factors
