Abstract: 
This paper presents modeling of Distribution STATCOM (d-STATCOM) in load flow calculations for the steady-state voltage compensation. An accurate model for d-STATCOM is derived to use in load flow calculations. The rating of this device as well as the direction of required reactive power injection for voltage compensation in the desired value (1 p.u.) is derived and discussed analytically and mathematically by the phasor diagram method. Furthermore, an efficient method for node and line identification used in load flow calculations is presented. The validity of the proposed model is examined by using two standard distribution systems consisting of 33 and 69 nodes, respectively. The best location of d-STATCOM for under voltage problem mitigation approach in the distribution networks is determined. The results validate the proposed model for d-STATCOM in large distribution systems.
