ارزيابي فني و اقتصادي استفاده از ادوات FACTS براي پخش بار بهينه در شبكه برق قم در راستاي تعديل بارگذاري خطوط انتقال و فوق توزيع منطقه

Abstract This research focuses on the technical an‎d economic eva‎luation of FACTS devices, with an emphasis on Static Var Compensators (SVC), within the transmission an‎d sub-transmission network of Qom province. To determine the optimal placement an‎d capacity of SVC units, two intelligent optimization approaches-Particle Swarm Optimization (PSO) an‎d Proximal Policy Optimization (PPO)-were employed. The algorithms were first tested on the IEEE 57-bus stan‎dard network to validate their accuracy an‎d convergence behavior. Subsequently, the developed Python-based codes were implemented in the DIgSILENT PowerFactory environment to optimize the location an‎d reactive power rating of SVCs in the real Qom network. The results demonstrate that installing SVCs at the proposed substations, such as Ghaleh Kamkar an‎d Sayyar Yazdanshahr, significantly improves voltage profiles, reduces line loading, an‎d enhances overall voltage stability. Furthermore, the economic assessment indicates that the PSO algorithm outperforms PPO in terms of both efficiency an‎d cost-effectiveness. Finally, considering the proposed development plan, which includes constructing a new 63 kV transmission line between Qom 1 an‎d Jamkaran substations, the optimized configuration can serve as a practical an‎d reliable foundation for sustainable network expansion an‎d operational planning in Qom’s power system.
