چکیده مقاله :
امروزه تعداد و اندازه ژنراتورهاي DG متصل به سيستمهاي توزيع با سرعت در حال افزايش است. منبع DG در طي عمليات بازيابي مي‌تواند با ايجاد يک جزيره عمدي باعث سرعت‌بخشيدن به عمليات بازيابي شود. جزيره عمدي جهت بالابردن قابليت اطمينان بارهاي انتهايي شبکه که به شاخه پشتيبان ديگري دسترسي ندارند يک گزينه مناسب است و در غير اين صورت اين بارها در اثر ايجاد يک خطاي دائمي بايستي قطعي طولاني را تجربه کنند. اين مقاله روشي جهت بازيابي بار شبكه‌هاي توزيع در حضور DG ارائه مي‌كند. روش ارائه‌شده، الگوريتمي مبتني بر جستجوي ممنوع با هدف كمينه‌كردن هزينه خاموشي مشتركين طي عمليات بازيابي بار است. در اين روش سعي شده كه با بازآرايي، ايجاد جزيره و در نهايت بارزدايي، بيشترين بار با بيشترين اهميت در كمترين زمان بازيابي شود. روش ارائه‌شده واحدهاي انرژي‌محدود و محل تجهيزات سنكرون‌سازي در شبكه را در نظر مي‌گيرد. اين روش بر روي يك شبكه تست 32 باس اجرا شده و نتايج آن ارائه شده است.
DGs connected to distribution systems are increasing in size and number. Intentional islanding are proper alternatives to increase the reliability of end load in the network with does not access to any other branch. In other conditions these loads experiences permanent interruption. in load restoration operation, islanding is so important in the presence of DGs. Islanding is occurred when a part of distribution network is supplied only from DG sources. A new algorithm for distribution load restoration in the presence of DGs is presented in this thesis. the proposed approach minimizes the load interruption cost in restoration process based on Tabu search method. In this algorithm the maximum load with the most level of importance is restored in minimum time by reconfiguration, islanding and finally load shedding. Energy storage units and the location of synchronizing devices are considered in this thesis. The algorithm is implemented on a 32-bus test system and numerical results are presented.
