This paper proposed the rooted tree optimization (RTO) algorithm to solve the optimal placement problem of distributed generation (DG) and distributed static compensator (DSTATCOM) in the distribution system to maximize the system benefits. Innovative formulas such as index of voltage profile enhancement (IVPE), index of loss reduction (ILR), and index of pollution reduction (IPR) are utilized to measure different aspects of the devices. The RTO algorithm is applied on the 33-bus distribution system considering a variable load and thereafter, the performances of the devices are judged on the basis of the different aspects. Furthermore, both DG and DSTATCOM are simultaneously placed and the overall system benefit is also investigated. The accuracy of the proposed RTO algorithm is checked by comparing it with others standard algorithms.
