ABSTRACT
Reactive power (or reactive volt-amperes) is a specifi c phenomenon occurring in an alternative current (AC) system. This kind of power does no real work for the electricity consumers but plays a very important role in power system engineering. Since the impedances of the network components are predominantly reactive, the transmission of real power requires a difference in voltage phase angle between the sending and receiving points, whereas the transmission of reactive power requires a difference in voltage magnitudes of these two adjacent buses, which are usually restricted to a 5-percent margin. Hence, to stay within the voltage limits, transmission of reactive power doesn’t reach very far and is regarded as local [1].
