چکیده مقاله :
در اين مقاله مسأله تعيين تعداد، موقعيت و ظرفيت منابع توليد پراکنده در شبکه‌هاي توزيع انرژي الکتريکي در حضور عدم قطعيت در اطلاعات بار و قيمت برق بازار انتقال، در قالب يک مدل رياضي با معيارهاي چندگانه فرموله‌بندي شده است. اهداف مکان‌يابي در مدل پيشنهادي عبارتند از: 1) کمينه‌سازي هزينه‌هاي سرمايه‌گذاري و بهره‌برداري، 2) کاهش ريسک‌هاي فني سيستم و 3) کاهش ريسک اقتصادي ناشي از عدم قطعيت‌ها. براي مدل‌سازي عدم قطعيت‌ها از تئوري مجموعه‌هاي فازي استفاده شده است. مدل رياضي پيشنهادي توسط ويرايش خاصي از الگوريتم ژنتيک حل شده است. نتايج اجراي مدل و روش پيشنهادي روي يک شبکه توزيع نمونه ارائه گرديده است.
This paper presents a new multiobjective model for optimal placement of distributed generation sources in electric distribution network under load and market price uncertainties that finds out the non-dominated multiobjective solutions corresponding to the simultaneous minimization of economic cost, technical risks, and economical risk due to uncertainties. Fuzzy sets theory is used to model the uncertainties. The proposed model is solved using a specialized genetic algorithm as the optimization tool. The performance of the proposed approach is assessed and appreciated by case study on a typical distribution network.
