The line and load data are given in reference [14]. ,2015) is applied to the 33 bus radial distribution system, the losses are reduced to 35%. It is a loop system with the total load of 3. The backward /forward sweep method saves computational time. The plots of voltage profile and branch power flows of the selected test networks are presented followed by numerical values of the simulation results. Bus 1 is taken as the point of common coupling (substation). 63 percent with four D-STATCOMs and cost of 2493146.
