چکیده

: جایابی و ظرفیت­یابی بهینه واحدهای تولید پراکنده و جبران­سازهای مدرن تاثیر مستقیمی بر روی کارایی این ادوات در سیستم توزیع دارد. به همین دلیل، در این مقاله، بهینه­سازی همزمان مکان و اندازه انواع منابع تولید پراکنده و جبران­ساز استاتیک سنکرون در سیستم­های توزیع مورد مطالعه قرار گرفته است. جهت نزدیک­تر کردن نتایج به شرایط واقعی­تر بهره­برداری، از یک مدل بار غیرخطی که ترکیبی از الگوری مصرف روزانه و بار متغیر به ولتاژ و فرکانس است، استفاده می­شود. میکروتوربین، توربین بادی، پنل فتوولتائیک و پیل سوختی به عنوان منابع تولید پراکنده در نظر گرفته می­شوند. توابع هدف مسئله ترکیبی از شاخص­های فنی و زیست­محیطی هستند. از الگوریتم بهینه­سازی چندهدفه وال برای بهینه­سازی توابع هدف و تشکیل صفحه بهینه پارتو استفاده می­شود. پس از اجرای الگوریتم چندهدفه، از روش تحلیل سلسله مراتبی برای انتخاب بهترین ذره از صفحه پارتو که معادل با بهینه­ترین مکان و اندازه ادوات است، استفاده می­شود. در نهایت، روش پیشنهادی در سیستم­های توزیع استاندارد 69 شینه IEEE و واقعی 101 شینه خوی- ایران مورد ارزیابی قرار می­گیرد. نتایج شبیه­سازی نشان­دهنده کارایی مناسب روش پیشنهادی در جایابی و ظرفیت­یابی بهینه ادوات و بهبود شاخص­های سیستم توزیع هستند.

چکیده [English]

Optimal allocation of distributed generation units and DFACTS affects the efficiency of these devices; for this reason, in this article, the simultaneous placement of distributed generation and Distributed-STATic-COMpensator (DSTATCOM) are done in the distribution system. The load model is considered as a combination of various customers’ daily load patterns and sensitive to voltage-frequency. The micro turbine, wind turbine, photovoltaic and fuel cell are considered as DG units. The objective functions of the problem consist of the technical index (the voltage stability and the active and reactive power loss) and environmental index (the amount of pollutant DG unit’s gas emissions). The whale optimisation algorithm (WOA) is used to multi-objective optimize the location and capacity of devices. After applying the multi-objective WOA, the analytical hierarchy process is utilized to select one of the Pareto optimal solutions as the best location and size of devices. The proposed algorithm is implemented on the 69-bus distribution system and actual 101-bus distribution system in Khoy–Iran. The results indicate the significant effect of load models and various DG units on the efficiency of the distribution system in the presence of DSTATCOM. Moreover, the indices of the distribution system are improved considerably after applying the proposed method.
