Abstract

Reducing system loss and improving voltage profile and stability are proposed in this study using a D-STATCOM in distribution systems. Three indices have been considered in the problem formulations to achieve the aforementioned objectives. To implement the proposed method, a D-STATCOM is modeled in power flow calculations to compensate the reactive power and improve the system performance. The Particle Swarm Algorithm (PSO) and Backward-Forward power flow method are used to solve this optimization problem. Two IEEE standard systems, IEEE 33-bus and 69-bus systems, have been selected to implement the proposed method. The simulation results demonstrate that using D-STATCOM in the distribution systems can effectively reduce system loss and improve system voltage profile and stability.
