Improving Loadability in Unbalanced Distribution Network using Flexible Step Voltage Regulator

Rapid load growth is increasing the strain on the distribution network, resulting in unacceptable voltage drops. The loadability limits on the distribution network can be enhanced by using voltage control devices. This paper examines the impact of the Flexible Step Voltage Regulator (FSVR) on the loadability of unbalanced distribution networks. FSVR can independently control the magnitude and angle of voltage in each phase, resulting in superior voltage regulation than traditional Step Voltage Regulators (SVR). To demonstrate the effect of FSVR on enhancing loadability, simulation tests are done on an IEEE 13 bus unbalanced distribution network.
