چکیده مقاله :
با گسترش روز افزون مصرف انرژی در دنیا، توسعه شبکه های قدرت امری ضروری است. اما ایجاد خطوط انتقالی جدید مستلزم صرف زمان و هزینه های گزاف بوده و لذا در صورت امکان استفاده از همان خطوط با ظرفیت انتقال بالاتر بسیار مقرون به صرفه می باشد. در همین راستا در سال های اخیر با معرفی FACTS به شبکه های قدرت، استفاده از آن ها در کشورهای صنعتی جهت افزایش ظرفیت خطوط انتقال متداول شده است. در این مقاله با تنظیم بهینه منابع توان راکتیو موجود در شبکه قدرت همراه با ادواتFACTS سری و موازی شامل (TCSC ،SVC) به منظور هماهنگی آنها با یکدیگر و با استفاده از الگوریتم های فراابتکاری مثل ازدحام ذرات به کاهش توان اکتیو، هزینه‌های عملیاتی سیستم از جمله هزینه ادواتFACTS و تراکم در شبکه‌های انتقال کمک می شود و در پایان با شبه سازی شبکه تست 30 باسه IEEE و قرار دادن ادوات FACTS در آن این امر اثبات خواهد شد.
The growing use of energy in the world necessitates the development of power networks. However, developing new transmission lines requires a great deal of time and cost, so it will be very cost-effective to use the same lines with higher transmission capacities, if possible. In this regard, in recent years, by introducing of FACTS to power networks, their use in industrialized countries has become commonplace to increase the capacity of transmission lines. In this paper, the optimal adjustment of reactive power sources in the power network with FACTS series and parallel devices (TCSC, SVC) in order to coordinate them with each other and using fuzzy logic based on evolutionary algorithms such as particle swarm to reduce power losses Active, operating system costs including the cost of FACTS devices and congestion in transmission networks. Finally, this will be proven by simulating the IEEE 30-Bus test network and placing FACTS devices on it.
