Voltage variations due to active power generation by solar PV systems coupled with operation of voltage regulators and switching of capacitor banks leads to change in reactive power flow in the lines [53]. For instance, if a capacitor is switched off, reactive power earlier being supplied by the capacitor is no longer available and needs to be imported from neighboring lines or utilities. This may also have financial impacts on the distribution utilities that have a high import component of power from neighboring utilities.
