Abstract

This paper presents modeling of Static Series Voltage Restorer (SSVR) unbalanced radial distribution system (RDS) load flow. To incorporate this approach, an accurate model for SSVR is derived to use in load flow calculations. SSVR reactive power rating as well as direction of required reactive power injection to compensate voltage of a particular node to the desired value (1p.u) is derived, discussed analytically, and mathematically. The validity of the proposed model is examined for distribution systems consisting of 25 nodes.The best location or under voltage problem mitigation in the distribution network is determined. The results show the validity of the proposed model for SSVR in large distribution systems.
